Evolution Essay
Evolution
Evolution is a complex process by which the characteristics of living organisms change over many
generations as traits are passed from one generation to the next. Many scientists agree on that
concept. They have been trying to develop this theory over hundreds of years to make it reasonable
and beliveable to people. But is evolution the reason that humans are on earth?
People that are not quite religious and have little faith in God believe in evolution. Those who
strongly stand by their beliefs supporting evolution, in my opinion, think they know enough about
science and biology and all the complexities of the cell and the human being that they forgot who
actually created all this. In the Bible, the Quran and most if...show more content...
This is prohibited genetically since all of the information for the development of an organism has
already been encoded in the DNA of its parent. Variation to organisms must remain within its basic
kind...evolutionists have tried to explain that natural selection happened in conjunction with
mutations to the genetic code. This could not produce evolution, however, since mutations do not
create new genetic potential, they just alter what is already there."3 Now genetic alteration, or
mutation is being taken place on animals like pigs and mice to try to have human DNA in their
cells. The chances of this taking place successfully is again very low.
Some evolutionists argue that anti–evolutionists' only sources are either religous or weak scientific
facts. The second law of thermodynamics is broadly accepted by many scientists and states that,
"...anything which is organized , tends with time, to become disorganized. Any physical system left
to itself will decay, or, lose energy and organization within the system...In other words, this law says
that the increase of information required for a life form to evolve could not happen as this increase
in information by itself violates the law."4 This disorganization is also called entropy.

Essay about Human Evolution and Adaptation
Over the course of evolution, humans have evolved to adapt the ever–changing conditions to
improve their chances of surviving. Is there still room for natural evolution or has the time come for
us to use our technological innovations and further our development beyond previously thought
possible by biological means. Past trends have shown that as time has passed, significant body
structures have changed to counteract the changes to our environment. The changes that have been
most significant are: dentation; brain size; muzzle angles; average body weight, skull structure. Will
these continue to change and progress along similar trend lines, or has the time come for the
evolution of our species to become technologically driven?
As humans...show more content...
However as the planet warmed, natural selection may have started to favour a slighter stature in
humans. Therefore, as the skeletons and skulls got smaller the brain shrunk in size as a result
(McAuliffe, 2011). Another theory that is circulating the science community is that the decrease in
cranial capacity is attributed to the arrival of agriculture
One theory is that H. sapiens have reached the end of the evolutionary line. As evolutionary changes
have occurred, it is known that these changes become fixed in isolated populations. For example, the
Galapagos Finches that evolved from the mainland species to survive in the unique habitat of the
isolated islands. When natural selection occurs, a genetic mutation, e.g. spine suited to bipedal
locomotion, is passed through the generations, as it provides some benefit to the value of life of the
organism. Eventually this mutated trait becomes the desired gene for further generations. However
if the populations where these mutations are occurring, the potential for significant mutations to take
effect within the gene pool decreases as a result of interbreeding between populations (Owen, 2009).
As H. sapiens have become extremely mobile, as in they can cover large distances thanks to the
development of technological innovations, the possibility between crossbreeding between separate
gene pools of different populations, the possibility that a potentially beneficial mutation can become
the desired gene is

Essay about Evolution
Charles Darwin had two great themes in "On the Origin of Species" which accounted for
the similarities and adaptations
characteristic of living organisms. To account for the adaptations of organisms and those
innumerable features that equip
them for survival and reproduction, Darwin (and Wallace) independently came up with the central
theory of evolutionary
process: natural selection. Natural selection gives insight in to why organisms are the way that they
are. Adaptations are
phenotypic variants that result in the highest fitness among a specified set of variants in a given
environment. In reference
to humans, there are many traits that have been selected and adapted for throughout their
evolutionary history giving...show more content...
These
ideas together constitute our idea of the evolutionary theory. When you factor in all of these
elements of evolution you can
view evolution as a "progressive development through time from simple to gradually more
complex and more diverse
organisms" (Ayala, 1997).
Darwin devoted one single sentence in "The Origin of Species" to the controversial topic
of human evolution: "Light
will be thrown on the origin of man and his history"(Futuyma, 1998). Although his evasion did
not work, human evolution
is still a controversial topic today. Since this area is so controversial there have been many studies
conducted in the area
of human evolution. These evolutionary studies have provided us with abundant, well–documented
evidence on the
relationship of humans to other species, on the steps by which some human characteristics evolved,

and on genetic
variation within and among human populations.
Some theorists believe that natural selection of random changes in nucleic acid sequences and
genetic information are
the primary agents of evolution. In a study done by J.L. Mountain and L.L. Cavalli–Sforza, it was
shown that natural
selection may have played a major role in the evolution of certain polymorphisms in humans. It was
found that the
frequencies of ancestral alleles of humans strengthen the conclusion that the earliest major separation
of modern humans

Evidence of Evolution Evolution is a complex and at times controversial topic. The theory of
evolution has been argued since it was first discovered by Charles Darwin. Evolution has many
misconceptions regarding how it came about and its process. The idea that there is an actual science
to how species evolved and continue to evolve is extraordinary. Evolution is a convoluted study that
deals with the continuous transformation of organisms and characteristics. According to Helena
Curtis and N. Sue Barnes, "In fact, evolution can be precisely defined as any change in the
frequency of alleles within a gene pool from one generation to the next." (Talkorigins.com) Over the
many years of Earth's existence, hundred upon thousands of creatures and plants have evolved
gradually over time creating new species. As the living–things transform, the characteristics and
organisms evolve as well. This transformation will continue just as it has in previous years. With this
change, new and old species alike will adapt to their surroundings and continue this never–ending
cycle....show more content...
It is a fact that species evolve, just as it is a fact that the sun rises in the West and sets in the East.
Helena Curtis and N. Sue Barnes voiced their opinion on the evidence of evolution and the
transformation of species, "massive additional evidence has accumulated supporting the fact of
evolution––that all living organisms present on earth today have arisen from earlier forms in the
course of earth's long history." (Talkorigins.com)The discoverer of evolutionary theoryCharles
Darwin, who suggested that evolution was similar to a tree and that new creations form on the
branches of the tree and the old creations fall away like dead limbs. Darwin's analogy went into

Evolution
There always has been a controversy whether evolution really did happen or not. Many evolutionists,
philosophers and biologists have presented sufficient evidence that evolution is true. Yet there is still
debate about this contentious topic. With the facts and findings of fossil records of earlier species,
ideas of initial theorists, and our own genetics and DNA, evolution can be hard to prove wrong.
Evolution is not just a change over time, but that all life on Earth shares a common ancestor. This
process is occurring in our lives right now. What exactly is evolution? Evolution is "the process
through which the characteristics of organisms change over successive generations, by means of
genetic variation". (What is evolution) Simply, descent with modification. Charles Darwin was the
first person with the acceptable explanation of evolution. Although his theory gave forth too many
tremendous advances, he did not build this theory on his own. He learned and built off earlier
theorists, like Jean–Baptiste Lamarck, "who indorsed linear evolution". (evolution) As well as
Aristotle, a Greek philosopher, with his concept of Scala Nature. These early theorists served as a
foundation for Charles Darwin's theory. Although Darwin's theory was important, a greater
attribution to evolution was founded. That is the uncovering of fossils. Fossils are significant to the
evolution because they show how life on Earth was

Essay on Evolution VS. Creationism
Since the beginning of the human race there has been a lingering question as to the origins of man
and how all living things acquired their characteristics. The two main theories that arose over time
were Creationism and Evolution, both of which provided very distinct answers to this question.
Creationism based its answer on the idea of a supernatural power or being that created the entire
universe, man and the numerous other organisms that live within it. While, Evolution theorizes that
all living things have the potential to change and grow over time into something new and different.
So in other words, one theory suggests that humans and all the organisms on Earth are the result of
divine design, while the other indicates that they...show more content...
Every one of these flaws points out that the Creationists theory that the Earth, all of the organisms on
it, and everything that surrounds it has not changed or been altered since the flood is inaccurate.
Biogeography for example shows that "closely allied" species have a tendency to live on the "same
continent... or within the same group of oceanic islands... despite their species–by–species
preferences for different habitats, food source, [and] of conditions of climate" (Quammen 4). The
explanation for this is that "they descended from common ancestors" and this can be verified with
the paleontology flaw because that flaw deals with the fossils of plants and animals "that had
[either] become extinct or that still existed but in different forms" which indicates not only that
organisms have changed over time, but also provides evidence that "closely allied" organism have
lived in the same areas of centuries (Quammen 4; Parks 24). Then in the taxonomic classification
flaw these "closely allied" spices can be "systematically classified, according to their shared
similarities" which, suggests that "closely allied" organisms descended from common ancestor
because of the traits and similar organs that allows this type of classification (Quammen 5). The
presence of these similar traits and organs introduces the flaw of vestigial characteristics because
although some of these do not have any current

Essay on human evolution
The central purpose of this essay is to critically discuss the importance of understanding human
evolution and the history of psychology for the modern psychologist. For the human evolution, the
essay will be addressing on how we and other species descended from our ancestors and how the
different environment has helped to us to become more adaptable. Regarding the history of
psychology, the essay will be discussing on how psychology branched off from the philosophy
approach to become its own science. The essay will then go on discussing how the understanding of
both human evolution and history of psychology would be used by modern psychologist.

They were full bipedal and their brain size and brain patterns evolved by increasing (590–687 cc).
Their diet was mainly meat which might have an influence on their rapid growth of their brains.
(Tobias 1987).
The next species to appear were the Homo erectus which might have descended from Homo habilis.
They were the first human whose fossils were found outside of Africa. They also had larger brain
than the species before them. Homo sapiens sapiens came after the Homo Neanderthalensis; they are
the only human species around. This could have been due to the result of increase brain sizes that
allows more cognitive abilities that help them adapt to different environment changes and hence
survive. Global evidence have been found of art, music, and culture and advanced tool making. In
Mithen's 3 phase of mind proposes that the shape of the Neanderthals' frontal lobe was similar to the
one of the modern Homo sapiens and this indicated that they were able to cope with complex
cognitive functioning. Evidence for this could be explained using the phonological approach by
Frank Gall (1758–1828).
Human evolution links with the history of psychology through Thomas Wynn's cognitive
archaeology. Thomas Wynn (1979) wanted to find the link between archaeology and psychology. He
used Piaget's theory of development to argue that old humans had functional operational intelligence

Thus, universal common ancestry entails the transformation of one species into another and,
consequently, macroevolutionary history and processes involving the origin of higher taxa. Because
it is so well supported scientifically, common descent is often called the by biologists. For these
reasons, proponents of special creation are especially hostile to the macroevolutionary foundation of
the biological sciences. This article dirThis article directly addresses the scientific evidence in favor
of common descent and microevolution.evolution, the overarching concept that unifies the biological
sciences, in fact embraces a plurality of theories and hypotheses. In evolutionary debates one is apt
to hear evolution roughly parceled between the terms "microevolution" and "macroevolution".
Microevolution, or change beneath the species level, may be thought of as relatively small scale
change in the functional and genetic constituencies of populations of organisms. That this occurs
and has been observed is generally undisputed by critics of evolution. What is vigorously challenged,

Evolution And Evolution Of Evolution
Evolution
Evolution, a change in the genetic makeup of a subgroup, or population, of a species (Nowicki 10).
Every living thing in the world is capable of evolving into something. Cells evolve to perform
different tasks and to become stronger. Charles Darwin is the founder of evolution, he realized that
species change over time to ensure survival. The future of evolution can not be predicted.
Everything in our universe starts out as a single celled organism. All life traces back to three billion
years ago, therefor all species have had a long time to evolve into what it is now.
Species evolve to ensure survival, to get a better sense of smell and eyesight. Some bugs have
evolved to have a hard exoskeleton that can stand a lot of pressure and won 't kill them. A duck
has evolved to produce oils on its feathers that make them waterproof and keeps them dry and
warm in very cold water. They have also evolved to have webbed feet that makes it easy to swim
through the water. The average household dog was once a wild untamed animal. Over time the
process of evolution has changed it into mans best friend. Some have evolved into great hunting
dogs, others just take naps all day. Their sense of smell, hearing, and sight are amazing but they didn
't get like that from the beginning, they evolved.
The importance of evolution helps us solve problems that impact our lives. An example of this is in
the field of medicine, to stay ahead of pathogenic diseases we must understand the

Is Evolution Real?
Evolution is "the process by which different kinds of living organisms are thought to have developed
and diversified from earlier forms during the history of the earth..". Evolution can show how man,
etc. have changed over time. Five things that prove evolution are, fossil records, embryology,
comparative anatomy, molecular biology, and direct observation. With evidence to back them up, I
will prove that these five things show evolution is real.
Fossil records play a big part in evolution. They show the remains of ancestors of animals, humans,
etc. Fossils are bones, bones can show the change/ development in the creature of which it derived
from. A lot of fossils look very similar to species today. This shows that a species can change/adapt

Homologous means "having the same relation, relative position, or structure, in particular.",
analogous means, "comparable in certain respects, typically in a way that makes clearer the nature of
the things compared.", and vestigial means, "forming a very small remnant of something that was
once much larger or more noticeable."
Molecular biology also has a lot to do with evolution. Molecular biology (DNA) is the study of
DNA. DNA is found in our cells. DNA is who we are. DNA can be traced back using advanced
technology. Using this we can compare and contrast the differences in DNA from past species to
present species.
Direct observation is the final evidence for evolution. By observing a species in their natural habitat,
you can see how they adapt. For example, the peppered moths. Originally they were white, with
black and grey specks. As the industrial revolution began, the trees they laid on for protection, started
to turn black. The moths then were being eaten by birds. The moths adapted to their environment,
and slowly became black with grey specks.
Overall, fossil records, embryology, comparative anatomy, molecular biology, and direct
observation, all support the idea of evolution. Each come into play at different times, but all are
needed to back up the idea of

The Theory of Evolution Essay
Biological evolution is the name for the changes in gene frequency in a population of a species from
generation to generation. Evolution offers explanation to why species genetically change over years
and the diversity of life on Earth. Although it is generally accepted by the scientific community,
Charles Darwin's theory of evolution has been studied and debated for several decades. In 1859,
Darwin published On The Origin of Species, which introduced the idea of evolutionary thought
which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of
the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all
life on Earth shares a common ancestor has been around for...show more content...
Over time the beak would become longer and those birds would survive. The next mechanism,
genetic drift, happens by chance. For example, a bug that is either red or green. If a large portion
of the red bug happens to get stepped on, the gene frequency for this species is now changed.
Mutation is another evolutionary mechanism that happens by chance. Mutation is when the
genetic material of an organism is altered. An example of this is albinism which has altered the
genes of several different animals. Evolution has been debated for many years. Most scientists
assume evolution to be true, but it is not officially proven. Evolution is known as "fact and
theory," because it is a fact that organisms have changed over time, but the mechanism that
changes those organisms is uncertain. One of the major debates regarding evolution is the belief
in creationism. Creationists believe that the Universe and organisms on Earth were all created by
a divine power. There are also some theories in which creationism and evolution coexist. One idea
is that the divine being who created the world used evolution as a method. Another idea is that
science and religion are actually the same thing and religion explains the unknown parts of science.
For example, science says that the world couldn't have been created in seven days, but one of God's
days may not be the same length

The History of Human Evolution
By definition, human evolution is the development, both biological and cultural, of humans. Human
ideologies of how the evolution of man came to be is determined by cultural beliefs that have been
adopted by societies going back as far as the Upper Paleolithic era, some 40,000 years ago. Through
the study of paleoanthropology, we have come to determine that a human is any member belonging to
the species of Homo Sapiens. Paleoanthropologists, while studying the evolution of humans, identify
and explain evolutionary changes that occur throughout time that aid in the development of the

Modern humans have a "braincase volume of between 79.3 and 91.5 cubic inches".(Gallagher)
Throughout the development of humans, one can notice that the brain has more than tripled in
size. This augmentation may be related to behavioral patterns of the hominids with an increase in
number and sophistication of stone tools and other artifacts. The art of tool making along with
other learnt skills made it possible for hominids to heighten their ability to live in a range of
different environments. "The earliest hominine fossils show evidence of marked differences in
body size, which may reflect a pattern of the different sexes in our early ancestors".(Gallagher)
Females tended to be smaller, weighing in at about 70 lbs and measuring 3 to 4 feet tall, while
men were on average 5ft tall and weighing 150lbs. This drastic size difference between genders
decreased through time, sometime after a million years ago. "The third major trend in hominine
development is the gradual decrease in the size of the face and teeth."(Microsoft Encarta) Unlike the
apes (from whom we derived) that were characterized by large, tusk–like canine teeth, the earliest
hominine remains were smaller in size and had canines that projected slightly. Also we can see a
reduction in the size of the face and jaws. "In early hominines, the face was large and positioned in
front of the braincase. As the teeth became smaller and the brain expanded,

Reflective Essay On Evolution
Do you find evolution as the right way to explain the starting of the universe? In my life, I was
always taught that the world started with the Big Bang and that there was no God in existence.
My thoughts on this changed when I was in seventh grade, or last year. In seventh grade, I was
taught a diverse way of seeing things. My teacher explained to me the existence of a God as well as
a new way of seeing the creation of the universe. He explained that God created the universe in
seven days by speaking words, contradicting the Big Bang. A short time later, he introduced me to a
man named Lee Strobel, an atheist who later became a Christian from the evidence of the existence
of the Christian faith. Strobel interpreted the evidence of God, the differences in evolution and
Christianity, and how to have faith in God. In the first video that I watched with Lee Strobel, it
referred to the evidence of a creator or God. The video explained that God existed before the
creation of man and the world. Continuing on the subject, the video spoke about Jesus and his
appearances to over five–hundred people. Jesus, referring to the trinity, includes the Father, the
Holy Spirit, and Jesus himself.Another part that I did not mention was that appearances were after
his death on the cross. After his death on the cross, he rose from the dead on the third day of his
death. Another part of the evidence of God would be science. In science, there have been multiple
evidences of the existence of God. Examples of this would be references of dinosaurs in the Bible.
In Job, it talks about a behemoth in Job forty. Another example would be in Numbers of flying
serpents that bit the Israelites. This is an example of how humans lived with dinosaurs and also that
the world was not billions of years, but only thousands of years, defining evolution. The first concept
to understand between evolution and Christianity is that they see the world completely differently.
In Bible class, we mainly focused on the differences in Christianity and evolution. The main point is
the age of the earth in both Christianity and evolution. In evolution, they believe that the earth is
about four–billion years in age. Christians are completely opposite and believe

Essay on Evolution
There are many mechanisms that lead to evolutionary change. One of the most important mechanism
in evolution is natural selection which is the differential success in the reproduction of different
phenotypes resulting from the interaction of organisms with their environment. Natural selection
occurs when a environment makes a individual adapt to that certain environment by variations that
arise by mutation and genetic recombination. Also it favors certain traits in a individual than other
traits so that these favored traits will be presented in the next generation. Another mechanism of
evolution is genetic drift. Genetic drift is a random change in a small gene pool due to sampling
errors in propagation of alleles or...show more content...
Some bacteria had genes that coded for enzymes that specifically destroyed certain antibiotics such
as ampicillin. From this incident, scientists were able to deduce that natural selection helped the
bacteria to inherit the genes for antibiotic resistance. Scientists have also been able to use
biochemistry as a source of evidence. The comparison of genes of two species is the most direct
measure of common inheritance from shared ancestors. Using DNA–DNA hybridization, whole
genomes can be compared by measuring the extent of hydrogen bonding between single–stranded
DNA obtained from two sources. The similarity of the two genes can be seen by how tightly the
DNA of one specie bonds to the DNA of the other specie. Many taxonomic debates have been
answered using this method such as whether flamingos are more closely related to storks or geese.
This method compared the DNA of the flamingo to be more closely related to the DNA of the stork
than the geese. The only disadvantage of this method is that it does not give precise information
about the matchup in specific nucleotide sequences of the DNA which restriction mapping does.
This technique uses restriction enzymes that recognizes a specific sequence of a few nucleotides
and cleaves DNA wherever such sequences are found in the genome. Then the DNA fragments are
separated by electrophoresis and compared to

Essay on Evolution, Immortality, and Humanity
Our ancient ancestors in the Neolithic Era only lived for an average of 20 years, an age now
considered to be only the beginning of adulthood. As human technology becomes more sophisticated
and knowledge of the ourselves and of nature expands, humans develop longer lifespans and the
general quality of life improves. In fact, we have more than tripled the lifespan of our ancestors
while retaining much of the same biological fitness. Humans have withdrawn from natural selection

With further sophistication and refinement, humans maybe able to develop immunities to most, and
hopefully all, of the diseases that have plagued humans since the dawn of human existence and
maybe even achieve immortality through biologically engineered cells that enable regeneration. This
possibility of escaping death, a fundamental element of the natural order, and of a continued,
human–directed path of evolution will force humanity to reinvent itself to fit the newly gained
abilities that are once thought to be only possible in science fiction and fantasies.
Thus, with the technological breakthroughs in genomics and cell encapsulation that can potentially
enhance the human body through internal implants or alterations, humans will increasingly take
control of the course of their evolution and fundamentally change humanity from its solely organic
nature to a state in which the natural and the artificial cooperate to function and evolve. First, this
new course evolution brings about the expansion of the definition of humanity beyond the
established perception. Secondly, the potential immortality of mankind made possible by technology
will lead to disastrous problems of overpopulation that will upset the existing social structures. Lastly,
the inevitable evolution of humanity will be either marked by the gradual evolution of the entire
human race or settled by a terrifying conflict between the Homo Sapiens, who are determined to
preserve the natural human essence, and

Argumentative Essay On Evolution
Evolution It has always been a mystery of how life on Earth started. Although we may not be able
to find out exactly how life originated, we can find out how life has changed over time through the
theory of evolution. Evolution is the process by which all living organisms come through a long
history of changes shaped by physical and chemical processes still taking place. There are debates
between whether the theory of evolution is truly scientific. The argument stems from why evolution
is considered a "theory." To many, a theory is simply defined as someone's opinion. Inbiology, a
theory is "an explanation of some natural phenomenon with well supported evidence from
experiments or observations" (Reed Wicander, 2012).
Discovery of Evolution
Between 1831 and 1836, Charles Darwin embarked on a five–year voyage after graduating from
Cambridge University with a degree in theology. Darwin made a visit to the Galapagos Islands,
where he made observations which changed his ideas on present–day species. The idea the people of
that time before his discovery held on to the concept of the fixity of species, where all species were
created in their current forms with little to no changes at all. After observing fossils of past
mammals and the 13 species of finches living on the island, Darwin realized that these animals came
from a common ancestor. After making such observations, he was convinced that "all living
organisms derived from ancestors that lived in the past with some

possibilities of electricity, and so many more wonderful scientists was the start of the "progress" that

His "discovery" had already been interpreted one way, all Newton did was reinterpret the observed
gravity in a new way, according to Kuhn. Isaac Newton gave science the observation of gravity that
pulls molecules together, without him, DNA could not be bound to the Universe and molecules
would never bond to one another. Darwin's Big Bang theory relies on the explanation of Gravity
through Isaac Newton. With Newton's science, other scientists made discoveries that built upon his
science to evolve the theoretical thoughts of the universe to Charles Darwin's evolution. Thomas
Kuhn believed that science did not build upon itself, but the systematic, rather than random, ways of
science lead to paradigm shifts when one discovery was found to be incorrect resulting in a new,
rather than expanded old, idea. When a shift occurs, new scientists emerge with open minds and new
ideas older scientists over–look. These new scientists begin new paradigms and the process of
discovery continues until imperfections are found with the current paradigm. Kuhn believed that the
newer scientists did not just build on the older scientists, but spun off in new directions.
Thomas Kuhn believed that Darwin's evolution had undergone shifts. He had many ideas of how
evolution occurred and toyed with many of them. According to Kuhn, changes in beliefs and ideas
after finding one belief did not

Evolution, the science of how populations of living organisms change over time in response to their
environment, is the central unifying theme in biology today. Evolution was first explored in its
semi–modern form in Charles Darwin 's
1859 book, Origin of Species by means of Natural Selection. In this book, Darwin laid out a strong
argument for evolution. He postulated that all species have a common ancestor from which they are
descended. As populations of species moved into new habitats and new parts of the world, they faced
different environmental conditions. Over time, these populations accumulated modifications, or
adaptations, that allowed them and their offspring to survive better in their...show more content...
The question is can humans evolve (physically), that is through changes of some sort to the general
human gene pool, enough to be considered a different species sometime in the future. The answer to
this is tricky. The answer is
"yes" if there is no human intervention and "not likely" (or atleast
controlled) if there is human intervention. The more interesting answer is the latter. The first answer
deserves some mention. Through the subtraction or addition (that is through chance changes of
some sort) of alleles (different forms of a characteristic gene) from the overall gene pool until homo
sapiens are no longer is feasible. One might ask how and were this is occurring. The answer is
human genes are changing all the time through radiation and spontaneous mutations (the latter more
rapidly no than ever since the human population is now larger than ever) and one can see these
changes to the overall gene pool in the disappearance of certain human tribes within parts of Africa
and South America..
These tribes unfortunately take exclusive alleles with them. What about Natural
Selection in present human culture. Some peoples are growing faster than others, for
example–Chinese faster than any other in the present world, thus the large
Chinese population.

Persuasive Essay On Evolution
Evolution has shaped many things into the way they are today, ranging from various animals to
even parasites! However, to understand this, we must know what evolution even is. Evolution is
any change to the genetic composition of a population(Nova, xx). Evolution is not fixed or entirely
random. Through various tools like reading and comparing genetic codes, making phylogenetic
trees, and observing physical traits, exploring and finding out how homo sapiens have evolved is so
interesting and easier than ever before! Homo sapiens have evolved from chimpanzees. In order for
evolution from chimpanzees to homo sapiens to happen, natural selection must take course. Natural
selection is when "nature decides which organisms survive." (Nova,n.d.). This happens through
reproduction and variation. Consequently, there will be mutations in the organism's genetic code.
This variation usually is what helps the organisms to survive in different locations. Only the most
reproductively successful will survive. For example, in a PBS Learning Media course video,
someone said that there was a theory that brown polar bears migrated to Antarctica, and they went
through assorted genetic mutations, and the bears who were able to survive became polar bears. To
prove the natural selection between chimps and humans, we share 98% of our genetic code with
chimpanzees. If we did not share 98% of our genetic code with them, we would have been further
distantly related. In addition to this, the

Essay about Evidence for Evolution
Evolution and DiversityвЂЁ
Evolution and DiversityThe foundation for the theory of evolution was laid by Charles Darwin
(Rose, n.d.). He developed hypotheses about natural selection which helped scientists develop the
theory. Evolution is a theory and not a hypothesis because evolution has been proven by vast
amounts of scientific data, research, and testing. The definition of a hypothesis is an educated
explanation that needs to be researched and tested but has not yet been proven (Earman, 1984).
There has been no scientific evidence to disprove the theory of evolution. The fossil record is
evidence of evolution. Fossils are often fingerprints of evolution. They help scientists track how

Many die before they are born or hatched depending on species, while many others don't survive
infancy and ultimately into their reproductive years. A portion of those that reach reproductive age
will never reproduce due to sterility or other factors. This is a part of the natural selection process. It
is often referred to as the, "survival of the fittest" (Frederic, 2011). It is hard to truly estimate
what fraction of offspring will survive to reproduction. There are always obstacles to survival for
an organism. Climate, food, habitat, and illness are just a few factors which affect natural
selection. Ultimately we know that some traits can increase survival rates for individuals such as
their color. We know from Darwin's research that a certain beak length was favorable in finches but
that was also dependent on yearly weather (Petren, 2005). Offspring that possess favorable traits are
more capable of surviving into adulthood and thus reproducing. We know from genetics that there is
an increased likelihood that their offspring would also possess that desirable trait. The population of
individuals possessing the trait would increase as more individuals possessing the trait survived to
reproductive years, and fewer without the trait did not. Natural selection can help prevent a species
from going extinct if they were to face adverse conditions that
