The document discusses how evolutionary biology can provide context for understanding human physiology and the origins of disease. It explains that many conditions traditionally viewed as defects or diseases, such as fever and pain, are actually evolved defenses that were beneficial for survival. Other origins of disease and physiological weaknesses can be understood through evolutionary concepts like constraints on design, trade-offs, and conflicts between organisms. The document uses examples like the blind spot in the human retina and vulnerabilities to new environmental factors to illustrate these evolutionary explanations for disease. It argues that considering medical problems from an evolutionary perspective, termed Darwinian medicine, provides a useful framework for research.

Write What is Right
Each step involved in the comprehensive literature search strategy include evaluating references to help find ideas of sources to use, searching by hand to avoid bias, reading “grey” conference proceedings and/or PhD theses, and contacting authors to get access to unpublished literature.
Each step as it applies to my capstone would be first looking at references from the online article
Study: the kidney shortage kills more than 40,000 people a year
, searching in library books starting with organ donation and leading to the shortage of organs, finding doctors who specialize in kidney transplant and see what their PhD thesis was based up, and contacting Dr. Pasavento who wrote the article
Facing Organ Donor Shortage, Patients Forced to Get Creative
.
The article
The Organ Shortage Crisis in America : Incentives, Civic Duty, and Closing the Gap
discusses how the cadaveric kidney donors are becoming insufficient to meet the needs of those in need of a transplant. The author states
“Nearly 120,000 people are in need of healthy organs in the United States (Flescher, 2018).”
It explains how they are trying to increase living donors to donate to those in need either related or unrelated (Flescher, 2018). The author states,
“Every ten minutes a new name is added to the list, while on average twenty people die each day waiting for an organ to become available.”
With that being said, some ideas include paying those for their kidneys or having them just spend a day at dialysis with a patient.
The article
Relieving the kidney donor shortage
, discusses how kidney transplantation is the only treatment for kidney failure. Having a kidney transplant is cheaper than dialysis, which is only a Band-Aid for kidney failure. Financial incentives are currently an idea to have the amount of living donors increase. This can be beneficial for both the donor and the recipient. The autho.

You will develop a formal information paper that addresses the legal basis of current Department of Homeland Security jurisdiction, mission, and responsibilities. You will need to specifically analyze hazards, to include manmade or technological and naturally occurring hazards, and terrorism, domestic and foreign, in the information paper.
You are an action officer in your local jurisdiction's Office of Homeland Security. This is a recently created office. As a medium-size jurisdiction, the city manager's office has dual responsibilities in many of the leadership and management positions. This is often referred to as being dual-hatted. The chief of police has been assigned as the director of the Office of Homeland Security for the city. She has no prior experience or knowledge of the requirements involved in homeland security and has asked you to provide a formal report on the topic. The chief intends to share this report with other office managers, city department heads, the city manager, and the elected officials of the city (mayor and city council).
Your report is an information paper and should be formatted as such. The report should address the following items:
The legal basis of current Department of Homeland Security jurisdiction, mission, and responsibilities
Legal definitions of hazards, to include manmade or technological and naturally occurring hazards
Legal definitions of terrorism, domestic and foreign
Review of state law and statutes (using your home or residency state) as it applies to hazards
Review of state law and statutes (using your home or residency state) as it applies to terrorism
Summarize your top 5 key points
Provide any recommendations that you may have to your city's leadership concerning homeland security issues

Write What is Right
Each step involved in the comprehensive literature search strategy include evaluating references to help find ideas of sources to use, searching by hand to avoid bias, reading “grey” conference proceedings and/or PhD theses, and contacting authors to get access to unpublished literature.
Each step as it applies to my capstone would be first looking at references from the online article
Study: the kidney shortage kills more than 40,000 people a year
, searching in library books starting with organ donation and leading to the shortage of organs, finding doctors who specialize in kidney transplant and see what their PhD thesis was based up, and contacting Dr. Pasavento who wrote the article
Facing Organ Donor Shortage, Patients Forced to Get Creative
.
The article
The Organ Shortage Crisis in America : Incentives, Civic Duty, and Closing the Gap
discusses how the cadaveric kidney donors are becoming insufficient to meet the needs of those in need of a transplant. The author states
“Nearly 120,000 people are in need of healthy organs in the United States (Flescher, 2018).”
It explains how they are trying to increase living donors to donate to those in need either related or unrelated (Flescher, 2018). The author states,
“Every ten minutes a new name is added to the list, while on average twenty people die each day waiting for an organ to become available.”
With that being said, some ideas include paying those for their kidneys or having them just spend a day at dialysis with a patient.
The article
Relieving the kidney donor shortage
, discusses how kidney transplantation is the only treatment for kidney failure. Having a kidney transplant is cheaper than dialysis, which is only a Band-Aid for kidney failure. Financial incentives are currently an idea to have the amount of living donors increase. This can be beneficial for both the donor and the recipient. The autho.

You will develop a formal information paper that addresses the legal basis of current Department of Homeland Security jurisdiction, mission, and responsibilities. You will need to specifically analyze hazards, to include manmade or technological and naturally occurring hazards, and terrorism, domestic and foreign, in the information paper.
You are an action officer in your local jurisdiction's Office of Homeland Security. This is a recently created office. As a medium-size jurisdiction, the city manager's office has dual responsibilities in many of the leadership and management positions. This is often referred to as being dual-hatted. The chief of police has been assigned as the director of the Office of Homeland Security for the city. She has no prior experience or knowledge of the requirements involved in homeland security and has asked you to provide a formal report on the topic. The chief intends to share this report with other office managers, city department heads, the city manager, and the elected officials of the city (mayor and city council).
Your report is an information paper and should be formatted as such. The report should address the following items:
The legal basis of current Department of Homeland Security jurisdiction, mission, and responsibilities
Legal definitions of hazards, to include manmade or technological and naturally occurring hazards
Legal definitions of terrorism, domestic and foreign
Review of state law and statutes (using your home or residency state) as it applies to hazards
Review of state law and statutes (using your home or residency state) as it applies to terrorism
Summarize your top 5 key points
Provide any recommendations that you may have to your city's leadership concerning homeland security issues

You must provide the history of the museum through the use of visual imagery. You might choose to display some of the objects/artifacts that would be included in the museum, audio or video clips related to the spaces, or text that might appear on the displays or signs at the museum. Be sure you have a title slide with the name of the museum you chose on it. Your final product should be very creative AND very realistic. You will have to do extensive research on the museum that you choose. Your audience should walk away from your presentation with the feeling that they have just left the museum. The audience should also gain new information about the culture that they did not know before your presentation. You will also need to submit a reference page using APA format.

The UN— “A More Perfect Union?”
Considering the readings, video presentations, and your own research, draft a quality 6–7-page research paper on the role, legitimacy, and authority of the UN according to the following prompts, answering in a separate or integrated manner as you wish.
Identify at least 3reasons that states might defend the intrinsic legitimacy of the UN as a governing authority. In reverse, identify at least 3reasons that states might criticize its legitimacy and authority.
In short, make an argument for the limits and possibilities of the UN as a legitimate governing authority in a world of sovereign states.
What is the relationship of the UN to the current international system of states?
Considering the reasons for the creation of the UN after WWII, does it seem driven by political necessity or the political utility? In plainer English, do states need the UN more than the UN needs the states? Or do states both large and small find the UN a useful tool for improving their relative power and legitimacy vis-à-vis other states and global institutions? Is there some position in-between?
Using other sources and extra-Scholar sources (The commentaries, teachings, other writings, etc.) to inform your own reasoning, comment on the compatibility with the idea of
World Government
. [
Attention
: The Instructor does not view the question as rhetorical, nor the answer self-evident. So, reason carefully.] For example, if the logic of collective action under the
Articles of Confederation
—the logic of state sovereignty—failed to secure American liberties as well as the ‘more perfect union’, the new Constitution established by the Framers in 1787 to replace it, effectively requiring states to cede sovereignty to a larger collective authority, why would the same logic of collective action not justify the UN as a ‘more perfect union’ to replace an anarchic system of sovereign states putting the world at risk in a nuclear age?

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Persuasive Message—Business Communication TrainingScenario .docx
1. Persuasive Message—Business Communication Training
Scenario:
You are a manager at a regional office of a mid-large sized
technology company, called NanoSmart Technologies. You
have noted that several of your colleagues in your regional
office struggle with professional business communication and
you believe that their lack of professionalism is costing the
company valuable business.
To collect data, you decide to personally mentor two of your
fellow team members in professional business communication,
measuring sales results before and after your intervention. To
your delight, each team member increased sales by 10% in one
month. You cannot allocate enough time to personally mentor
everyone in the office, but you believe that you might be able to
convince the National Manager of NanoSmart to provide
funding to formally train 15 additional employees at your
regional office.
To get training course cost estimates, you visit the website of a
credible training organization, the American Management
Association (AMA). You select an appropriate course and
research the training costs
(http://www.amanet.org/training/seminars/communication-
skills-training.aspx). Once you determine the approximate
amount you must request, you write a logical, yet persuasive
message to convince the National Manager, Dana Buckminster,
to approve and fund the training course.

98% Alike --- Jonathan Marks
" Human and chimps are said to differ b a mere 2 percent of
our DNA." ( Park 81) the introduction of the article "98%
Alike" cited that. When we examine their own DNA, discovery
and chimpanzee is not much different. But it is precisely
because these small but subtle differences, completely changed
the world, let us become a "human".You don't have to be a
biologist or anthropologists, can see the great apes - gorillas,
chimpanzees, bonobos and orangutans -- similar to how much
we humans.
In addition to them in some parts of the body is too large and
long have more hair, even if the child can see that they are the
3. same with us. Scientists decades ago concluded that
chimpanzees are our closest relatives, the its about 98% the
same as the human genes. This 2% of extremely subtle genetic
differences, scattered throughout the genome, is the root of all
the other differences. Farming, language, painting, music,
technology and philosophy, all these civilization achievements
will humans and chimps separated, and put on a suit of
chimpanzees as ridiculous as it seems.
The author uses clam and logical tone. He uses lots of data
to explain why human and chimpanzees are different. For
example, he writes in his articla, " Because DNA is a linear
array of those four bases... have no ancestry in common will
match at about one in every four sites." Even we are 98%
similar with chimpanzees but still have huge different.
I never knew that the DNA of human and chimpanzees are
98% matching until I take this class. I got to know the structure
of DNA and what made human and chimpanzees different. This
article is really interesting to read.
Evolution as Fact and Theory ---- Stephen Jay Gould
This article talks about the creationism and evolution. He
states "Creationism is any conviction that a higher power had a
hand in the origin of the universe, the earth, and, most
important, its living beings." ( Park 48) This is how the author
understand about creationism. There are plenty of scientists
consider themselves creationists. Evolution says that human was
evolved from other animals. He believe that the evolution is the
fact. There are lots of evidences show that evolution is ture,
fossil record is a powerful evidence.
The author has a emotional tone. H states " I am both angry
at and amusedby the. Creationists; but mostly I am deeply sad."
( Park 52 ) He express his point of view straightly. He defend
4. the "theories" of evolution is the fact with lots of evidence to
profit. On the other hand, creationism is theory and lack of
evidence. He also believe that if you want to prove your
hypothesis, you have to collect evidences.
Evolution and creationism are controversial. People has
different belief and views about this topic. The theory of
evolution is just a seem arguable "Hypothesis" , rather than the
Law or facts, otherwise wouldn't be so far is still debated. When
the article puts forward the theory of evolution, he indeed is a
fossil as main evidence. But now fossil also become one of the
major weakness of evolution, because between species, there are
too many "Missing link". Evolution has two types: the first is
emphasized the "microevolution" subtle evolution within
species, the second is stressed by the lower evolved into higher
creature "evolution". After is the focus of the scientists argue,
just also to resist the bible. But christians do not oppose the
former. In fact, wide evolution is can't be directly confirmed by
the experiment or any methon.
Article: Sex, Drugs, Disasters and the Extinction of Dinosaurs
Dinosaurs were appeared in the millions years ago, and
prosperity in the end of the Mesozoie reptiles. The main reasons
cause dinosaurs extincted are sex, drugs and disasters. First of
all, the temperature suddenly dropped sharply, resulting in lived
in the warm shallow sea, land and many kinds of dinosaurs
quickly perish the marsh. "Cold-blooded animals lacking a
physiological mechanism for keeping their temperatures
constant."(Park25) Because of temperatures decreased, hatched
is female or make offspring. The gender is not smooth,
inevitably leads to the dinosaurs. The second reason is drug.
During that period, Earth gymnosperms disappearing, replaced
by a large number of angiosperms, these plants contains no
toxin in gymnosperm, form a huge dinosaur eat far, intake of
angiosperm cause body endotoxin accumulation is overmuch,
5. was finally killed. Carnivorous animals eat the meat from the
toxic after was also killed. The third idea is disasters. At the
time of bacteria is in the midst of the extinction of dinosaurs, he
think is likely to be a plague bacteria caused these huge the
disappearance of the dinosaurs. Disease popular led to the
destruction of the dinosaurs, the reason is that the dinosaurs do
not have the immune system and reproductive is very slow.
Parasites to the spread of the virus to a dinosaur, lead to their
extinction, mammals from the same period, however, survive
the reason is that they are not affected by disease.
The author uses the emotional tone describe the reasons how
dinosaurs became extincted. He said " My greatest unhappiness
with most popular presentations of science concerns their
failure to separate fascinating claims from the methods that
scientists use to establish the facts of nature. The author atated
that the scients express the information using the boring way. It
is hard to catch their attention for science. He suggests that
people should show the information in a way that can arouse
people's interest or controversy about it. It will make more
people pay attention on science. Otherwise, people will not be
able to understand the information. The connection is important.
I agree with the author that most people does not familier
and not interested in science. Although science article is really
interesting to read but a it is hard to read with two much
academic vocabularies and make people does not want to finish
reading it.
T
houghtful contemplation of the human body elicits awe—in
equal measure
6. with perplexity. The eye, for instance, has long been an object
of wonder,
with the clear, living tissue of the cornea curving just the right
amount, the
iris adjusting to brightness and the lens to distance, so that the
optimal quantity of light
focuses exactly on the surface of the retina. Admiration of such
apparent perfection soon
gives way, however, to consternation. Contrary to any sensible
design, blood vessels and
nerves traverse the inside of the retina, creating a blind spot at
their point of exit.
The body is a bundle of such jarring contradictions. For each
exquisite heart valve, we
have a wisdom tooth. Strands of DNA direct the development of
the 10 trillion cells that
make up a human adult but then permit his or her steady
deterioration and eventual
death. Our immune system can identify and destroy a million
kinds of foreign matter, yet
many bacteria can still kill us. These contradictions make it
appear as if the body was de-
signed by a team of superb engineers with occasional
interventions by Rube Goldberg.
7. In fact, such seeming incongruities make sense but only when
we investigate the origins
of the body’s vulnerabilities while keeping in mind the wise
words of distinguished geneti-
cist Theodosius Dobzhansky: “Nothing in biology makes sense
except in the light of evo-
lution.” Evolutionary biology is, of course, the scientific
foundation for all biology, and bi-
ology is the foundation for all medicine. To a surprising degree,
however, evolutionary bi-

ology is just now being recognized as a
basic medical science. The enterprise of
studying medical problems in an evolu-
tionary context has been termed Dar-
winian medicine. Most medical research
tries to explain the causes of an individ-
ual’s disease and seeks therapies to cure
or relieve deleterious conditions. These
efforts are traditionally based on con-
sideration of proximate issues, the
straightforward study of the body’s
anatomic and physiological mecha-
nisms as they currently exist. In con-
trast, Darwinian medicine asks why the
body is designed in a way that makes
us all vulnerable to problems like can-
cer, atherosclerosis, depression and
choking, thus offering a broader con-
text in which to conduct research.
The evolutionary explanations for the
body’s flaws fall into surprisingly few
categories. First, some discomforting
conditions, such as pain, fever, cough,
vomiting and anxiety, are actually nei-
ther diseases nor design defects but rath-
er are evolved defenses. Second, conflicts
12. with other organisms—Escherichia coli
or crocodiles, for instance—are a fact
of life. Third, some circumstances, such
as the ready availability of dietary fats,
are so recent that natural selection has
not yet had a chance to deal with them.
Fourth, the body may fall victim to trade-
offs between a trait’s benefits and its
costs; a textbook example is the sickle
cell gene, which also protects against
malaria. Finally, the process of natural
selection is constrained in ways that
leave us with suboptimal design features,
as in the case of the mammalian eye.
Evolved Defenses
P
erhaps the most obviously useful de-
fense mechanism is coughing; peo-
ple who cannot clear foreign matter
from their lungs are likely to die from
pneumonia. The capacity for pain is also
certainly beneficial. The rare individu-
als who cannot feel pain fail even to ex-
perience discomfort from staying in the
same position for long periods. Their
unnatural stillness impairs the blood
supply to their joints, which then dete-
riorate. Such pain-free people usually die
by early adulthood from tissue damage
and infections. Cough or pain is usually
interpreted as disease or trauma but is
actually part of the solution rather than
13. the problem. These defensive capabili-
ties, shaped by natural selection, are
kept in reserve until needed.
Less widely recognized as defenses are
fever, nausea, vomiting, diarrhea, anxi-
ety, fatigue, sneezing and inflammation.
Even some physicians remain unaware
of fever’s utility. No mere increase in
metabolic rate, fever is a carefully regu-
lated rise in the set point of the body’s
thermostat. The higher body tempera-
ture facilitates the destruction of patho-
gens. Work by Matthew J. Kluger of the
Lovelace Institute in Albuquerque, N.M.,
has shown that even cold-blooded liz-
ards, when infected, move to warmer
places until their bodies are several de-
grees above their usual temperature. If
prevented from moving to the warm
part of their cage, they are at increased
risk of death from the infection. In a
similar study by Evelyn Satinoff of the
University of Delaware, elderly rats,
who can no longer achieve the high
fevers of their younger lab companions,
also instinctively sought hotter environ-
ments when challenged by infection.
A reduced level of iron in the blood is
another misunderstood defense mecha-
nism. People suffering from chronic in-
fection often have decreased levels of
blood iron. Although such low iron is
sometimes blamed for the illness, it ac-
14. tually is a protective response: during
infection, iron is sequestered in the liver,
which prevents invading bacteria from
getting adequate supplies of this vital
element.
Morning sickness has long been con-
sidered an unfortunate side effect of
pregnancy. The nausea, however, coin-
cides with the period of rapid tissue dif-
ferentiation of the fetus, when develop-
ment is most vulnerable to interference
by toxins. And nauseated women tend
to restrict their intake of strong-tasting,
potentially harmful substances. These
observations led independent research-
er Margie Profet to hypothesize that the
nausea of pregnancy is an adaptation
whereby the mother protects the fetus
from exposure to toxins. Profet tested
this idea by examining pregnancy out-
comes. Sure enough, women with more
nausea were less likely to suffer miscar-
riages. (This evidence supports the hy-
pothesis but is hardly conclusive. If Pro-
fet is correct, further research should
discover that pregnant females of many
species show changes in food prefer-
ences. Her theory also predicts an in-
crease in birth defects among offspring
of women who have little or no morn-
ing sickness and thus eat a wider vari-
ety of foods during pregnancy.)
Another common condition, anxiety,
obviously originated as a defense in
15. dangerous situations by promoting es-
cape and avoidance. A 1992 study by
Lee A. Dugatkin of the University of
Louisville evaluated the benefits of fear
in guppies. He grouped them as timid,
ordinary or bold, depending on their
reaction to the presence of smallmouth

16. MUCH SUFFERING is unnecessary but inevitable
because of the smoke-detector nature of our defens-
es. The cost of a false alarm—a strong reaction such
as vomiting in the absence of a true threat to life—is
temporary unpleasantness. But the cost of no alarm
in the presence of a true threat, such as a food toxin,
could mean death. A lack of defensive response dur-
ing pregnancy, for example, could kill the fetus.CR

bass. The timid hid, the ordinary sim-
ply swam away, and the bold main-
tained their ground and eyed the bass.
Each guppy group was then left alone
in a tank with a bass. After 60 hours,
40 percent of the timid guppies had
survived, as had only 15 percent of the
ordinary fish. The entire complement of
bold guppies, on the other hand, wound
up aiding the transmission of bass genes
rather than their own.
Selection for genes promoting anxious
behaviors implies that there should be
people who experience too much anxi-
ety, and indeed there are. There should
also be hypophobic individuals who
have insufficient anxiety, either because
of genetic tendencies or antianxiety
drugs. The exact nature and frequency
of such a syndrome is an open question,
as few people come to psychiatrists com-
plaining of insufficient apprehension.
But if sought, the pathologically non-
anxious may be found in emergency
rooms, jails and unemployment lines.
The utility of common and unpleas-
ant conditions such as diarrhea, fever
and anxiety is not intuitive. If natural
selection shapes the mechanisms that
18. regulate defensive responses, how can
people get away with using drugs to
block these defenses without doing their
bodies obvious harm? Part of the answer
is that we do, in fact, sometimes do our-
selves a disservice by disrupting defenses.
Herbert L. DuPont of the University
of Texas at Houston and Richard B.
Hornick of Orlando Regional Medical
Center studied the diarrhea caused by
Shigella infection and found that people
who took antidiarrhea drugs stayed sick
longer and were more likely to have
complications than those who took a
placebo. In another example, Eugene
D. Weinberg of Indiana University has
documented that well-intentioned at-
tempts to correct perceived iron deficien-
cies have led to increases in infectious
disease, especially amebiasis, in parts of
Africa. Although the iron in most oral
supplements is unlikely to make much
difference in otherwise healthy people
with everyday infections, it can severely
harm those who are infected and mal-
nourished. Such people cannot make
enough protein to bind the iron, leaving
it free for use by infectious agents.
On the morning-sickness front, an
antinausea drug was recently blamed for
birth defects. It appears that no consid-
eration was given to the possibility that
the drug itself might be harmless to the
fetus but could still be associated with
19. birth defects, by interfering with the
mother’s defensive nausea.
Another obstacle to perceiving the
benefits of defenses arises from the ob-
servation that many individuals regu-
larly experience seemingly worthless re-
actions of anxiety, pain, fever, diarrhea
or nausea. The explanation requires an
analysis of the regulation of defensive re-
sponses in terms of signal-detection the-
ory. A circulating toxin may come from
something in the stomach. An organ-
ism can expel it by vomiting, but only
at a price. The cost of a false alarm—
vomiting when no toxin is truly pres-
ent—is only a few calories. But the pen-
alty for a single missed authentic alarm—
failure to vomit when confronted with
a toxin—may be death.
Natural selection therefore tends to
shape regulation mechanisms with hair
triggers, following what we call the
smoke-detector principle. A smoke
alarm that will reliably wake a sleeping
family in the event of any fire will nec-
essarily give a false alarm every time the
toast burns. The price of the human
body’s numerous “smoke alarms” is
much suffering that is completely nor-
mal but in most instances unnecessary.
This principle also explains why block-
ing defenses is so often free of tragic con-
20. sequences. Because most defensive reac-
tions occur in response to insignificant
threats, interference is usually harmless;
the vast majority of alarms that are
stopped by removing the battery from
the smoke alarm are false ones, so this
strategy may seem reasonable. Until,
that is, a real fire occurs.
Conflicts with Other Organisms
N
atural selection is unable to pro-
vide us with perfect protection
against all pathogens, because they tend
to evolve much faster than humans do.
E. coli, for example, with its rapid rates
of reproduction, has as much opportu-
nity for mutation and selection in one
day as humanity gets in a millennium.
And our defenses, whether natural or
artificial, make for potent selection forc-
es. Pathogens either quickly evolve a
counterdefense or become extinct. Am-
herst College biologist Paul W. Ewald
has suggested classifying phenomena
associated with infection according to
whether they benefit the host, the path-
ogen, both or neither. Consider the run-
ny nose associated with a cold. Nasal
mucous secretion could expel intruders,

Changes in virulence relate to the life history of the infectious
agent and itsmode of transmission. As elucidated by Paul W.
Ewald of Amherst College, in-
22. fection requiring direct contact will ordinarily drive a pathogen
toward a state of low-
ered virulence, because the host must remain mobile enough to
interact with others.
But intermediaries that spread disease-causing agents, even
from totally incapacitated
hosts, can cause a change toward more virulence. Behavioral
choices, such as safer
sex, can also alter the makeup of the pathogen.

new hosts or both [see “The Evolution
of Virulence,” by Paul W. Ewald; Sci-
entific American, April 1993]. An-
swers could come from studies examin-
ing whether blocking nasal secretions
shortens or prolongs illness, but few
such studies have been done.
Humanity won huge battles in the
war against pathogens with the devel-
opment of antibiotics and vaccines. Our
victories were so rapid and seemingly
complete that in 1969 U.S. Surgeon
General William H. Stewart said that it
was “time to close the book on infectious
disease.” But the enemy, and the power
of natural selection, had been underes-
timated. The sober reality is that patho-
23. gens apparently can adapt to every
chemical researchers develop. (“The war
has been won,” one scientist more re-
cently quipped. “By the other side.”)
Antibiotic resistance is a classic dem-
onstration of natural selection. Bacteria
that happen to have genes that allow
them to prosper despite the presence of
an antibiotic reproduce faster than oth-
ers, and so the genes that confer resis-
tance spread quickly. As shown by No-
bel laureate Joshua Lederberg of the
Rockefeller University, they can even
jump to different species of bacteria,
borne on bits of infectious DNA. Today
some strains of tuberculosis in New
York City are resistant to all three main
antibiotic treatments; patients with those
strains have no better chance of surviv-
ing than did TB patients a century ago.
Stephen S. Morse of Columbia Univer-
sity notes that the multidrug-resistant
strain that has spread throughout the
East Coast may have originated in a
homeless shelter across the street from
Columbia-Presbyterian Medical Center.
Such a phenomenon would indeed be
predicted in an environment where
fierce selection pressure quickly weeds
out less hardy strains. The surviving
bacilli have been bred for resistance.
Many people, including some physi-
cians and scientists, still believe the out-
24. dated theory that pathogens necessarily
become benign after long association
with hosts. Superficially, this makes
sense. An organism that kills rapidly
may never get to a new host, so natural
selection would seem to favor lower
virulence. Syphilis, for instance, was a
highly virulent disease when it first ar-
rived in Europe, but as the centuries
passed it became steadily more mild.
The virulence of a pathogen is, howev-
er, a life history trait that can increase
as well as decrease, depending on which
option is more advantageous to its genes.
For agents of disease that are spread
directly from person to person, low vir-
ulence tends to be beneficial, as it al-
lows the host to remain active and in
contact with other potential hosts. But
some diseases, like malaria, are transmit-
ted just as well—or better—by the inca-
pacitated. For such pathogens, which
usually rely on intermediate vectors like
mosquitoes, high virulence can give a
selective advantage. This principle has
direct implications for infection control
in hospitals, where health care workers’
hands can be vectors that lead to selec-
tion for more virulent strains.
In the case of cholera, public water
supplies play the mosquitoes’ role. When
water for drinking and bathing is con-
taminated by waste from immobilized
25. patients, selection tends to increase vir-
ulence, because more diarrhea enhanc-
es the spread of the organism even if in-
dividual hosts quickly die. But, as Ewald
has shown, when sanitation improves,
selection acts against classical Vibrio
cholerae bacteria in favor of the more
benign El Tor biotype. Under these con-
ditions, a dead host is a dead end. But a
less ill and more mobile host, able to in-
fect many others over a much longer
time, is an effective vehicle for a patho-
gen of lower virulence. In another ex-
ample, better sanitation leads to dis-
placement of the aggressive Shigella
flexneri by the more benign S. sonnei.
Such considerations may be relevant
for public policy. Evolutionary theory
predicts that clean needles and the en-
couragement of safe sex will do more
than save numerous individuals from
HIV infection. If humanity’s behavior
itself slows HIV transmission rates,
strains that do not soon kill their hosts
have the long-term survival advantage
over the more virulent viruses that then
die with their hosts, denied the oppor-
tunity to spread. Our collective choices
can change the very nature of HIV.
Conflicts with other organisms are
not limited to pathogens. In times past,
humans were at great risk from preda-
tors looking for a meal. Except in a few
places, large carnivores now pose no
26. threat to humans. People are in more
danger today from smaller organisms’
defenses, such as the venoms of spiders
and snakes. Ironically, our fears of small
creatures, in the form of phobias, prob-
ably cause more harm than any interac-
tions with those organisms do. Far more
dangerous than predators or poisoners
are other members of our own species.

sources. Violent conflicts between indi-
viduals are overwhelmingly between
young men in competition and give rise
to organizations to advance these aims.
Armies, again usually composed of
young men, serve similar objectives, at
huge cost.
Even the most intimate human rela-
tionships give rise to conflicts having
medical implications. The reproductive
interests of a mother and her infant, for
instance, may seem congruent at first
but soon diverge. As noted by biologist
Robert L. Trivers in a now classic 1974
paper, when her child is a few years old,
the mother’s genetic interests may be best
served by becoming pregnant again,
whereas her offspring benefits from con-
tinuing to nurse. Even in the womb there
is contention. From the mother’s vantage
point, the optimal size of a fetus is a bit
smaller than that which would best
serve the fetus and the father. This dis-
cord, according to David Haig of Har-
vard University, gives rise to an arms
28. race between fetus and mother over her
levels of blood pressure and blood sug-
ar, sometimes resulting in hypertension
and diabetes during pregnancy.
Coping with Novelty
M
aking rounds in any modern hos-
pital provides sad testimony to
the prevalence of diseases humanity has
brought on itself. Heart attacks, for ex-
ample, result mainly from atherosclero-
sis, a problem that became widespread
only in this century and that remains
rare among hunter-gatherers. Epidemi-
ological research furnishes the informa-
tion that should help us prevent heart
attacks: limit fat intake, eat lots of veg-
etables, and exercise hard each day. But
hamburger chains proliferate, diet foods
languish on the shelves, and exercise
machines serve as expensive clothing
hangers throughout the land. The pro-
portion of overweight Americans is one
third and rising. We all know what is
good for us. Why do so many of us con-
tinue to make unhealthy choices?
Our poor decisions about diet and
exercise are made by brains shaped to
cope with an environment substantially
different from the one our species now
inhabits. On the African savanna, where
the modern human design was fine-
29. tuned, fat, salt and sugar were scarce
and precious. Individuals who had a
tendency to consume large amounts of
fat when given the rare opportunity had
a selective advantage. They were more
likely to survive famines that killed
their thinner companions. And we, their
descendants, still carry those urges for
foodstuffs that today are anything but
scarce. These evolved desires—inflamed
by advertisements from competing food
corporations that themselves survive by
selling us more of whatever we want to
buy—easily defeat our intellect and
willpower. How ironic that humanity
worked for centuries to create environ-
ments that are almost literally flowing
with milk and honey, only to see our
success responsible for much modern
disease and untimely death.
Increasingly, people also have easy
access to many kinds of drugs, especial-
ly alcohol and tobacco, that are respon-
sible for a huge proportion of disease,
health care costs and premature death.
Although individuals have always used
psychoactive substances, widespread
problems materialized only following
another environmental novelty: the
ready availability of concentrated drugs
and new, direct routes of administra-
tion, especially injection. Most of these
substances, including nicotine, cocaine
and opium, are products of natural se-
30. lection that evolved to protect plants
from insects. Because humans share a
common evolutionary heritage with in-
sects, many of these substances also af-
fect our nervous system.
This perspective suggests that it is not
just defective individuals or disordered
societies that are vulnerable to the dan-
gers of psychoactive drugs; all of us are
susceptible because drugs and our bio-
chemistry have a long history of inter-
action. Understanding the details of
that interaction, which is the focus of
much current research from both a
proximate and evolutionary perspec-
tive, may well lead to better treatments
for addiction.
The relatively recent and rapid in-
crease in breast cancer must be the re-
sult in large part of changing environ-
ments and ways of life, with only a few
cases resulting solely from genetic ab-
normalities. Boyd Eaton and his col-
leagues at Emory University reported
that the rate of breast cancer in today’s
“nonmodern” societies is only a tiny
fraction of that in the U.S. They hypoth-
esize that the amount of time between
menarche and first pregnancy is a cru-
cial risk factor, as is the related issue of
total lifetime number of menstrual cy-
cles. In hunter-gatherers, menarche oc-
curs at about age 15 or later, followed
within a few years by pregnancy and
31. two or three years of nursing, then by
another pregnancy soon after. Only be-
tween the end of nursing and the next
pregnancy will the woman menstruate
and thus experience the high levels of
hormones that may adversely affect
breast cells.
In modern societies, in contrast, men-
arche occurs at age 12 or 13—probably
at least in part because of a fat intake
sufficient to allow an extremely young
woman to nourish a fetus—and the first
pregnancy may be decades later or nev-
er. A female hunter-gatherer may have a
total of 150 menstrual cycles, whereas
the average woman in modern societies
has 400 or more. Although few would
suggest that women should become
pregnant in their teens to prevent breast
cancer later, early administration of a
burst of hormones to simulate pregnan-
cy may reduce the risk. Trials to test
this idea are now under way at the Uni-
versity of California at San Diego.
Trade-offs and Constraints
C
ompromise is inherent in every
adaptation. Arm bones three times
their current thickness would almost
never break, but Homo sapiens would
be lumbering creatures on a never-end-
32. ing quest for calcium. More sensitive
ears might sometimes be useful, but we
would be distracted by the noise of air
molecules banging into our eardrums.
Such trade-offs also exist at the ge-
netic level. If a mutation offers a net re-
productive advantage, it will tend to in-
crease in frequency in a population
even if it causes vulnerability to disease.
People with two copies of the sickle cell
gene, for example, suffer terrible pain
and die young. People with two copies
of the “normal” gene are at high risk of
death from malaria. But individuals with
one of each are protected from both ma-
laria and sickle cell disease. Where ma-
laria is prevalent, such people are fitter,
in the Darwinian sense, than members
of either other group. So even though
the sickle cell gene causes disease, it is
selected for where malaria persists.
Which is the “healthy” allele in this en-
vironment? The question has no answer.
There is no one normal human ge-
nome—there are only genes.
Many other genes that cause disease
must also have offered benefits, at least
in some environments, or they would
not be so common. Because cystic fibro-
sis (CF) kills one out of 2,500 Cauca-
sians, the responsible genes would ap-

pear to be at great risk of being elimi-
nated from the gene pool. And yet they
endure. For years, researchers mused that
the CF gene, like the sickle cell gene,
probably conferred some advantage.
Recently a study by Gerald B. Pier of
Harvard Medical School and his col-
leagues gave substance to this informed
speculation: having one copy of the CF
gene appears to decrease the chances of
the bearer acquiring a typhoid fever in-
fection, which once had a 15 percent
mortality.
Aging may be the ultimate example
of a genetic trade-off. In 1957 one of us
(Williams) suggested that genes that
cause aging and eventual death could
nonetheless be selected for if they had
other effects that gave an advantage in
youth, when the force of selection is
stronger. For instance, a hypothetical
gene that governs calcium metabolism
so that bones heal quickly but that also
happens to cause the steady deposition
of calcium in arterial walls might well
be selected for even though it kills some
older people. The influence of such
pleiotropic genes (those having multiple
effects) has been seen in fruit flies and
flour beetles, but no specific example has
yet been found in humans. Gout, how-
34. ever, is of particular interest, because it
arises when a potent antioxidant, uric
acid, forms crystals that precipitate out
of fluid in joints. Antioxidants have
antiaging effects, and plasma levels of
uric acid in different species of primates
are closely correlated with average
adult life span. Perhaps high levels of
uric acid benefit most humans by slow-
ing tissue aging, while a few pay the
price with gout.
Other examples are more likely to
contribute to more rapid aging. For in-
stance, strong immune defenses protect
us from infection but also inflict contin-
uous, low-level tissue damage. It is also
possible, of course, that most genes that
cause aging have no benefit at any age—
they simply never decreased reproduc-
tive fitness enough in the natural envi-
ronment to be selected against. Never-
theless, over the next decade research
will surely identify specific genes that
accelerate senescence, and researchers
will soon thereafter gain the means to
interfere with their actions or even
change them. Before we tinker, howev-
er, we should determine whether these
actions have benefits early in life.
Because evolution can take place only
in the direction of time’s arrow, an or-
ganism’s design is constrained by struc-
tures already in place. As noted, the
35. vertebrate eye is arranged backward.
The squid eye, in contrast, is free from
this defect, with vessels and nerves run-
ning on the outside, penetrating where
necessary and pinning down the retina
so it cannot detach. The human eye’s
flaw results from simple bad luck; hun-
dreds of millions of years ago, the layer
of cells that happened to become sensi-
tive to light in our ancestors was posi-
tioned differently from the correspond-
ing layer in ancestors of squids. The
two designs evolved along separate
tracks, and there is no going back.
Such path dependence also explains
why the simple act of swallowing can
be life-threatening. Our respiratory and
food passages intersect because in an
early lungfish ancestor the air opening
for breathing at the surface was under-
standably located at the top of the snout
and led into a common space shared by
the food passageway. Because natural
selection cannot start from scratch, hu-
mans are stuck with the possibility that
food will clog the opening to our lungs.
The path of natural selection can even
lead to a potentially fatal cul-de-sac, as
in the case of the appendix, that vestige
of a cavity that our ancestors employed
in digestion. Because it no longer per-
forms that function, and as it can kill
when infected, the expectation might
36. be that natural selection would have
eliminated it. The reality is more com-
plex. Appendicitis results when inflam-
mation causes swelling, which compress-
es the artery supplying blood to the ap-
pendix. Blood flow protects against
bacterial growth, so any reduction aids
infection, which creates more swelling.
If the blood supply is cut off complete-
ly, bacteria have free rein until the ap-
pendix bursts. A slender appendix is es-
pecially susceptible to this chain of
events, so appendicitis may, paradoxi-
cally, apply the selective pressure that
maintains a large appendix. Far from
arguing that everything in the body is
perfect, an evolutionary analysis reveals
that we live with some very unfortunate
legacies and that some vulnerabilities
may even be actively maintained by the
force of natural selection.
Evolution of Darwinian Medicine
D
espite the power of the Darwinian
paradigm, evolutionary biology is
just now being recognized as a basic
science essential for medicine. Most dis-
eases decrease fitness, so it would seem
that natural selection could explain only
health, not disease. A Darwinian ap-
proach makes sense only when the ob-
ject of explanation is changed from dis-
eases to the traits that make us vulnera-
37. ble to diseases. The assumption that
natural selection maximizes health also
is incorrect—selection maximizes the
reproductive success of genes. Those
genes that make bodies having superior
reproductive success will become more
common, even if they compromise the
individual’s health in the end.
Finally, history and misunderstanding
have presented obstacles to the accep-
tance of Darwinian medicine. An evo-
lutionary approach to functional analy-
sis can appear akin to naive teleology
or vitalism, errors banished only recent-
ly, and with great effort, from medical
thinking. And, of course, whenever evo-
lution and medicine are mentioned to-
gether, the specter of eugenics arises.

APPENDIX is most likely here
to stay. Evolutionary pressure
selects against the smaller ap-
pendix (above), because inflam-
mation and swelling can cut off
its cleansing blood supply, mak-
ing infections more life-threat-
ening. Larger appendices are
thus actually selected for.

Discoveries made through a Darwinian
view of how all human bodies are alike
in their vulnerability to disease will of-
fer great benefits for individuals, but
such insights do not imply that we can
or should make any attempt to improve
the species. If anything, this approach
cautions that apparent genetic defects
may have unrecognized adaptive sig-
nificance, that a single “normal” ge-
nome is nonexistent and that notions of
“normality” tend to be simplistic.
The systematic application of evolu-
tionary biology to medicine is a new
enterprise. Like biochemistry at the be-
ginning of this century, Darwinian med-
icine very likely will need to develop in
several incubators before it can prove
its power and utility. If it must progress
only from the work of scholars without
funding to gather data to test their ideas,
39. it will take decades for the field to ma-
ture. Departments of evolutionary biol-
ogy in medical schools would acceler-
ate the process, but for the most part
they do not yet exist. If funding agen-
cies had review panels with evolution-
ary expertise, research would develop
faster, but such panels remain to be cre-
ated. We expect that they will.
The evolutionary viewpoint provides
a deep connection between the states of
disease and normal functioning and can
integrate disparate avenues of medical
research as well as suggest fresh and
important areas of inquiry. Its utility and
power will ultimately lead to recogni-
tion of evolutionary biology as a basic
medical science.

DEFENSES and DEFECTS are two fundamentally different
manifestations of disease
BLOCKING defenses has costs as well as benefits
Because natural selection shapes defense regulation
according to the SMOKE-DETECTOR PRINCIPLE, much
defensive expression and associated suffering are
unnecessary in the individual instance
Modern epidemics are most likely to arise from the
mismatch between PHYSIOLOGICAL DESIGN of our
bodies and NOVEL ASPECTS of our environment
41. Our DESIRES, shaped in the ancestral environment to lead
us to actions that tended to maximize reproductive
success, now often lead us to disease and early death
The body is a bundle of COMPROMISES
There is no such thing as “the NORMAL body”
There is no such thing as “the NORMAL human genome”
Some GENES that cause disease may also have benefits,
and others are quirks that cause disease only when they
interact with novel environmental factors
GENETIC SELF-INTEREST will drive an individual’s actions,
even at the expense of the health and longevity of the
individual created by those genes
VIRULENCE is a trait of the pathogen that can increase as
well as decrease
SYMPTOMS of infection can benefit the pathogen, the
host, both or neither
Disease is INEVITABLE because of the way that organisms
are shaped by evolution
Each disease needs a PROXIMATE EXPLANATION of why
some people get it and others don’t, as well as an
EVOLUTIONARY EXPLANATION of why members of
the species are vulnerable to it
Diseases are not products of natural selection, but most
of the VULNERABILITIES that lead to disease are shaped
by the process of natural selection
42. Aging is better viewed as a TRADE-OFF than a disease
Specific clinical recommendations must be based on
CLINICAL STUDIES; clinical interventions based only on
theory are not scientifically grounded and may cause harm
A Darwinian approach to medical practice leads to a shift in
perspective. The following principles
provide a foundation for considering health and disease in an
evolutionary context:
