Evolution And Evolution Of Evolution
Most things in science all eventually lead back to one thing, evolution. Evolution has been an
interesting topic since mankind could wrap its mind around the concept. Whether one believes in
it or not, it is hard to deny the cold hard facts that back up how every being has changed from its
original form of life. From plants to humans, everything has adapted and evolved to be able to
adjust to climate changes, habitats disappearing, and new predators. All it takes is for one mutated
gene to get a foothold and aid in the survival of a species for the evolu–tion to begin. Although many
will try and disagree, evolution has played a large role in every living beings survival. Even with
evolution being such a key part of science, it did not quite start out that way. "Pre–Darwinian
science, heavily influenced by theology, held that all organisms were created simultaneously by God
and that each distinct life–form remained fixed and unchanging from the moment of its creation"
(Audesirk). This idea lasted for many years, 427–347 B.C., as great philosophers preached of this
grand idea without anyone challenging their words (Audesirk). It gave a simple and easy answer to
the tough question of how everything came to be, which was enough for most people. It wasn 't until
1707–1788 when George Louis LeClerc suggested that maybe the original sets of life had changed
over time (Audesirk). This claim was bold and un–heard of before, and many viewed it as
blasphemy. "However, by the 19th

Why Do You Believe In The Theory Of Evolution
Introduction
Do you believe in the theory of evolution? There are many people who believe evolution is how
humans came to be in today's world. Charles Darwin was the first to publish work on the theory
in 1859, concluding it is the process by which organisms change over time as a result of changes
in heritable physical or behavioral traits. Over the years scientists have began trying to prove this
theory is real. The theory has two main points, all life is connected and related to each other and the
diversity is a product of modifications of populations by natural selection. Modern scientists have
gone even further to branch off of the theory to make more points of the theory such as natural
selection, origin of species, and modern understanding....show more content...
In today's society there are a strong number of individuals who strongly believe it is true. The
theory is untrue from the majority's point of view. This is because there are no hard facts to
prove we have all evolved from the same specimen. The only type of evolution is how animals
adapt to an environment over time, but to say we all came from the same cell is just not
provable. To see that a lot of people believe in a loosely supported and the theory was created by
man when there was little to no religion. There's more proof in the religion of Christianity than
evolution because of religious sites and the places that are spoken of in the bible are actual cities.
There's nothing but the words of a man that came from his imagination. Charles Darwin made a lot
of valid points but he did not know what modern people know today. Darwin did not know about
DNA and the specifics of each species. If Darwin had all the details of today's scientists, he would
have not believed in evolution.
Conclusion
The theory of evolution is a debatable topic. It can go either way depending on the person, but the
simple fact is that there is no proof to support the theory. Scientists have tried to find any realism in
the theory but it is just too far fetched to have any concrete evidence. It is a personal opinion in
whether someone believes in evolution or not but it is almost more

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

In the year 1859, Charles Darwin developed the theory of evolution and since then, scientists
globally have been studying and trying to figure out exactly how we arrived on this planet.
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.
Life started about 3.8 billion years ago when the earth was formed as comets delivered water and
energy to the earth. Then simple single cells formed and genes combined through sexual variation.
Two cells merged together during sex. Genes were combined and a third cell was created as a sort of
mutation when genes were duplicated. Next a few cells were so...show more content...
Scientists then found that light sensitive cells dominated the population through natural selection. 300
billion years ago, those cells became sea organisms and one was able to breath air thus letting air
travel to a new organ and creating the opportunity for land organisms such as lizard–like arthropods.
They roamed on land and eventually adapted to the surrounding heat of the sun and rough ground.
Sexual reproduction occurred when the arthropods could no longer fertilize eggs through the tough
outer shells so instead fertilized the eggs inside of the female's body. Brains evolve with new
information and jaw bones become larger, capable of crushing heftier food. 250 million years ago

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 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

Two Arguments On The Theory Of Evolution
Evolutionism is supported by most people. There are two arguments on the theory of evolution. The
first argument is that evolution is caused by natural selection, such as the birds of the Galapagos
Islands. Because of different food made of different mouth type of bird, after the environment
changed, the food source changed, causing the birds died, this is the result of natural selection.
The second argument is that all creatures are genetically related. In the anatomy, although whales'
appearance just like fish, but the other part is more similar with the mammals, and in the early
embryonic development process also like mammals,
Genetics also found that the closest DNA sequence of whale was hippopotamus, probably they had a
common ancestor

The Future Of Human Evolution Essay
The Future of Human Evolution
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.

What is the theory of evolution? Many people who don't understand science or Biology
don't know how to answer this question. "Evolution is the process of biological change by which
descendants come to differ from their ancestors." In our society today, there is many conflicts
that exist between creationism which is the belief that a higher power created the Earth and
made living things and the theory of evolution. Some people are debating whether to teach
evolution in schools because the subject is very touchy to others. In other areas of the world,
there is wars against religion and evolution. I am on both sides. I don't really care about either
because they both sound pretty good to me. Evolution makes sense to me. I like the history of
evolution. It's so cool to see how different species have evolved throughout time.

Thus, universal common ancestry entails the transformation of one species into another and,

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

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

Creationism vs. Evolution Essay
Where we come from is a question as old as mankind itself. There are countless numbers of
religions, each with their own twist on the origins of earth and mankind, but one of the most highly
visible debates would be creationism vs. evolution. Depending on where your beliefs lie, the Earth
has been around somewhere in the neighborhood of 6,000 years to 4.5 billion years. One would tend
to believe that this vast difference in time would make it impossible to have 2 "theories" that are
so widely accepted. However this debate gives you just that. Each argument has its variations,

Under the same idea, the "Old Earth" train of thought is that the "days" mentioned in Genesis were
actually up to many millions of years each. This is one of many "theories" that justifies the actual
age of the Earth being around 4.5 billion years old. The third view states that the story of creation
contained in Genesis is not a literal or even a chronological account of happenings. It is instead a
guide promoting a six–day workweek with the seventh day a day of worship to God. The last view is
much like the second, in that it considers the "days" to be God's workdays, which may or may not
be equal to an Earth calendar day. Each day represents a period of time that God performed a major
task. Each view has the same underlying concept that God created everything, and the way it is
today, it the way it was when it was created.
Webster's Dictionary defines evolution as a theory that the various types of animals and plants have
their origin in other preexisting types and that the distinguishable differences are due to modification
in successive generations. Like creation, evolution is not immune from differing of opinions.
Evolution is split between two frames of though, naturalistic and theistic.
Naturalistic evolution is pretty much cut and dry. It simply states that life started as a single
one–celled organism. The universe was created 14 billion years ago, and the Earth was

Evolution Argumentative Essay
Evolution by definition is a theory that describes a change in one or more heritable characteristics of
a population from generation to generation. As a theory, evolution is not a proven fact. Instead
evolution is simply a theory that has been supported by evidence. While evolution has not been
proven correct, many people still believe in this theory–or so we thought. Several people still do not
believe in the theory of evolution for various reasons such as believing that god created all living
organisms and these organisms have stayed the same, while others are afraid of evolution.
Before getting into the debate of evolution, we must first understand what it means to be correct in
science. Foremost, not many things in science are correct, things like theories are just highly
supported by evidence. Once evidence is found that contradicts the theory or idea, the theory is then
eliminated or altered to fit the evidence. For instance, evolution was first defined as "descent with
modification or changes in characteristics of populations over time" (Biology, 362). However the
current definition accounts for changes in allele frequencies over time since new evidence has been
found that shows alleles change...show more content...
For instance, fossils found in sedimentary rock help provide evidence such as determining
evolutionary change in organisms. However, some people think that fossils are placed by the devil
in order to get humans to doubt god (Martin and Dawson). After all, "Gallup poll found 45 percent
of the population [was] in agreement that 'God created humans pretty much in their present form at
one time within the last 10,000 years'" (Sampson, 217). In other worlds, 45 percent of the population
believes that organisms have not changed since god put them here on Earth. Thus, the evidence that
fossils provide mean very little to people who do not believe in

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

Evolution Hypothesis
The purpose of this experiment was to test if evolution was occurring, and if so what type. Evolution
is when either the genotype frequency or the allele frequency changes overtime within a population.
In other words, it is when the genotypes of a population change. The change can be due to a number
of things, but the two this experiment tested were genetic drift and natural selection. If natural
selection were to occur, the allele frequency would be changing consistently, but one allele would
constantly be greater than the other. If genetic drift was to occur, we would end up with many more
of one type than the other, and the change would not be consistent. Evolution within a population is
very significant, and has many real–world applications....show more content...
We know that there is some type of genetic drift in each population, but we needed to do deeper
research to see which had a stronger influence. We came up with three hypotheses and predicted
what the results would be for each one. The first hypothesis was that evolution would occur. The
results would show allele frequencies had changed for that hypothesis to be proved correct. If there
was no change in the frequencies after the colonies formed, evolution would not have occurred. The
second hypothesis, assuming that evolution occurred, was that genetic drift would be the resulting
cause. If this was true, the allele frequencies wouldn't be equal. Our third, and final, hypothesis,
assuming that evolution occurred, would be that the cause of it was natural selection. However, it is
unlikely that both would occur, because the p–value would prove one or the other correct, not both

were then able to count how many colonies of each genotype had formed. After seeing how many
colonies had formed, we were able to find the chi–square value, which is how we figured out which
hypotheses we could

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

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

Because of this, they are unable to make scientific and logical connections between us humans and

Closely related organisms have very similar DNA. It turns out humans share over 90% of the same
DNA with ape–like creatures. We can conclude that they have a relatively recent common ancestor.
Another way to determine the relatedness of two organisms is finding fossils of a species that
displays an intermediate stage between the two existing ones. This intermediate species most
likely became extinct, but not before some of them evolved even more towards humans. The
proposed common ancestor between humans and apes is likely an extinct species named "Pan
Prior". It gets pretty in depth from there, but there is no current fossil existing of it, but analysis of
its DNA shows many signs of a common ancestor. It most likely existed 8 million years ago. The
ape is the most closely related living organism to the human. It is evident that species so similar
must have a common ancestor.
3. The eye cannot evolve from natural selection When evolution skeptics want to attack Darwin's
theory, they often point to the human eye.
How could something so complex have developed through random mutations and natural selection,
even over millions of years? Although there are only a few examples, there is evidence of an eye
changing slowly overtime due to the advantage it gave. Most likely, the eye only started out as a
light–sensitive patch on the head of an organism. That patch must have given that organism some
sort of advantage. Slowly, the eye became deeper and more open.

Evidence of Evolution The theory of evolution is the process how organisms on Earth change over
time by natural selection. The theory of evolution is so widely known that it is almost universally
accepted, except for a few people that think otherwise. For a theory to become so widely known
and established, there has to have been evidence to back it up. The most prominent pieces of
evidence for evolution are often cited as biogeography, homology, analogy, direct evidence, and
paleontology. Each of these pieces of evidence provide indication for evolution. Biogeography is
the study of where life is found and where their descendants were living in the past. Before Darwin,

Analogous structures have similar structures, but a different origin. They also have similar functions.
An example of analogy that supports the theory of evolution is speciation. Speciation is defined as
the biological change over time by which new species arrive. Some might wonder how analogous
structures come to be. Different species usually become more alike because of convergent evolution.
For example, two species can live in different but similar environments and need to fill the same
niche in different places on Earth. Because natural selection is the same around the world, the
species will go through similar styles of adaptations. Animals with advantageous adaptations will
be able to pass on their genes through reproduction. Reproduction continues until the advantageous
adaptation is the only one left. Occasionally, the favorable variation can change the structure of
the species. Limbs can be lost, gained, or changed, creating analogous structures in diverse
species that live in similar niches and surroundings, but don't live in the same places. A more
specific example is the similarity between the wings of birds and bats. A widespread adaptation for
many species, the wings of birds and bats are analogous as flight structures. The wings of both
animals have developed by different paths. In bats, the surface of the wing is a membrane without
feathers whereas birds have wings covered in feathers. Although both animals can fly and have
wings, they are different in many other places. Birds and bats just happen to fill the flying niche of

The Process of Evolution
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," "Google." Google.
Google, n.d. Web. 11 Apr. 2015.Evolution is the reason there is change in the genetic makeup of a
population, the reason organisms are linked by common ancestors, and evolution is still happening
today because of the constant change in environment. This paper focuses on these subjects within
evolution and will explore all areas of the process of evolution that creates diversity and unity in life.
One key component of evolution is natural selection. Natural selection is a theory, first presented by
Charles Darwin, that is well known across the globe. It is the reason why there is change of genetic
makeup in evolution. Natural selection is caused by the variation between generations, as well as the
survival of different individuals with different combinations of traits. The theory poses that
organisms with characteristics that increase their probability of survival will be given the chance to
produce more offspring. This means that the organism is more "fit". These offsprings are then given
the benefiting characteristic. With time more variation throughout the species will develop. For an
example of why evolution is dependent on natural selection Berkeley College talks about a
population of beetles.
