What is Evolution?
Evolution is the modification of characteristics of living organisms over generations
(StrangeScience.net, 2015); it is the gradual process of development by which the present diversity
of living organisms arose from the earliest forms of life, which is believed to have been ongoing for
at least the past 3000 million years (Hine, 2004). Common ancestry are groups of living organisms
that share the most recent common ancestor, by which scientific evidence proves that all life on
Earth are descendants from the previous universal ancestor (DarwinWasRight.org, 2015).
Additionally, opposing theories against Evolution, primarily the Christianity religion, explain that
God is the 'creator' and is the source of all existence.
Jean–Baptiste Lamarck (1755–1829) is one of the best–known early evolutionists, holding a belief
that evolution was a continuous development and strived toward greater complexity and perfection.
Through which, his theory of evolution was that living organisms evolved in a unceasingly up ward
direction, from dead matter, through simple to more complex forms and towards human
"perfection" (Nesci.edu, 2015). From his theories of Inheritance of Acquired Characteristics; where
organisms adapt to their environments and those changes were passed onto their off springs
(Corbis, 2001), to his theories of Use and Disuse, where organisms that are not used progressively
disappear (Evolution.berkeley.edu, 2015). Lamarck was the first biologist to publish

All living organisms in one way or another interact with the natural eco–system that is on Earth,
which consists of the mixture of atmospherical, ocean, and land systems. As time progressed, the
eco–system of Earth changed resulting in genetic mutation, migration to different environments
better suited to preferred habitats, and extinction. Genetic mutations appeared in cases that led to the
birth of new species by creating further genetic differences that allows more of a kind of species to
survive by increase the chances of producing offspring and give adaptations to survive based around
a new habitat. Furthermore, responses to environmental factors show that records of some organisms
responded by creating change to their environments instead of themselves. Humans, with larger
brains than other animals, have shown to do this substatially well as they possess greater intelligence
than other life forms on Earth. This raises the possibily that environmental factors affected the
evolution processes of Homo sapiens. From the study of fossil records from dispersive
environmental conditions, they show to have stimulated developmental features because of the
environment thus affecting human evolution. Over the years, diverse groups of human ancestry have
emerged from different climates with evidence of adaptaions such as, little to no body hair, heavy
amounts of hair on face and head, skin color, upright walking, increase of cranial size, and ability to
understand the creation and

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

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 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

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.

Evolution Of Evolution And Evolution
Title: Evolution
Author: Annette Gonzalez
December 9, 2014
Abstract:
This paper will cover the topic of evolution of organisms. Evolution is the process of constant
change from a lower, more simple to better, complex state (Merriam–Webster, 2014). In this essay,
there are different philosophies that support the idea of evolution. For instance, there is anatomical,
homology, natural selection evidence. This ideas will be explained in more detail in the body of
the paper. Besides this, the report will explicate how evolution of organisms does not occur in the
course of time, rather organisms give rise to other animals. In addition, the paper will clarify what
causes mutations in genes. Moreover, it will elucidate what sexual recombination means and how it
is relevant in relation to evolution. Lastly, there will be an explanation to why evolution of
organisms will come to a dead end at some point.
Introduction:
There are three main categories in relation to evolution that will be presented. The first section
clarifies Charles Darwin's contribution to the concept of evolution. Specifically, the different theories
of evolution Darwin supported with evidence are explained. The second part of the paper clarifies
how genes and DNA are responsible for the evolution of organisms. In the third section, evolutionary
trends in organisms are revealed.
Charles Darwin:
According to Stanley, Charles Darwin was a main contributor to the idea of evolution. He

The Theory of Evolution Essay
The ongoing scientific investigation of how exactly evolution occurred and continues to occur has
been an argumentative idea amongst society since Darwin first articulated it over a century ago. The
scientific basis of evolution accounts for happenings that are also essential concerns of religion; both
religion and science focus on the origins of humans and of biological diversity. For instance, in the
reading "Truth Cannot Contradict Truth," Pope John Paul II, addressing the Pontifical Academy of
Science, discussed the matter of God as creator of man. The Pope explains that men cannot relate to
animals because men are superior. The reasoning for that is because God created humans under his
likeness. What the church is saying about mankind...show more content...
"If no such variations exist, the population rapidly goes extinct because it cannot adapt to a changing
environment" (O'Neil, 1998–2013). Scientists call this reproductive success. "Within a specific
environment context, one genotype will be better than another genotype in survival or reproduction
for certain reasons having to do with the way its particular features relate to the environment or relate
to other organisms within the population" (Futuyma, 2000–2014). The theory of evolution is
explicable through various kinds of scientific research. In the science of paleontology, the history of
life is studied. Paleontologists study fossils to learn the past ecologies, evolution, and the origins of
humans. In order to understand the processes that have led to both the origination and destruction of
organisms since life began, paleontologists incorporate both scientific knowledge and studies. Fossil
findings are critically important for confirming predictions of evolution theory. Of the many
discoveries that are made yearly to add depth to the understanding of evolution, an example is a
recent discovery of a creature they named Tiktaalik. The Tiktaalik was uncovered to be a transitional
animal between shallow–water fishes and limbed animals. The creature supports the idea that it
emerged from both mammals and reptiles, suggesting that the two are related. These findings
support prediction of evolution, contradicting the belief that God

Growing Up In Oliver's Evolution By John Updike
Growing Up Growing up can be hard, even from a young age no one wants to get older. "Oliver's
Evolution" by John Updike is about just that, growing up. This story shows the life of a boy
named Oliver from an outside perspective. From his beginning when her was a boy through him
getting married and having a kid of his own. This story can be interpreted so many different ways.
The one that seems to show up no matter if analysing the story itself or its meaning to the author
himself is that a person grows as they progress through life. One way the story can be interpreted
is that the story represents Mr. Updike's leaving Esquire magazine, seeing as this was the last story
that he wrote for them. A few years after this was published Mr. Updike passed away of lung
cancer. When writing this story it could have resembled him reminiscing on his own life and what
has affected him to make him the man he was. Another interpretation could be that like Oliver

This being that it is about growing up and having to change and make choices in life. The story
gives the readers Oliver's background which is an incite as to why he is the way he is. From
being one of the youngest, coming years after this older siblings, to his parents divorce, grades
slip etc. we see how all of this played a role in Oliver's outcome as a person. As the story
progresses it gives subtle hints of him getting older and more mature. One being the comment about
his teeth, " his teeth were small and round and widely spread–baby teeth", this shows that even at
this part in his life, when he was in college, that he had not really grown as a person. It is not until
later in the story when he meets his girl friend/ wife that the readers start to see how he grows as a
person. He starts to hold the jobs he gets to create an income for him and his

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

These were vital to their progress, transformation to humans, and were evident during the early ape,
Australopithecus as well as the later Homo existence. Even though there have been many
archaeological findings that have provided useful information on this subject, there is still a lot that
remains unanswered. There still remains a missing link in the change from monkeys to humans."
Recent research, however, has provided so many 'links' in the form of fossil evidence that one
scholar has remarked:" It would be far more truthful to say that it is the chain that is missing whilst
the links exist."(( Posnanksy in Zamani, 1974, pg.53) –Shillington 2). If America wants to make
progress in this area, requiring this subject to be taught in high schools would be a very positive
step. The more students that are educated about evolution at a young age, the more there will be
who seek professions in this field as adults. A new generation of talented and highly qualified
scientists in this area would propel the world closer to finding explanations and answers in the future.
Even though no one can see or feel it, we as humans are in the process evolving right now. Human
evolution is inevitable, and will not stop unless the world comes to an end. Learning about human
evolution, in a since, is learning about yourself and how we came to be. Keeping this in mind, I feel
that students

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

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

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,
however it comes down to either God created the Earth and all things in it as they are now or that
life today has evolved from a...show more content...
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

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
their

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

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 Future Of Human Evolution Essay

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.

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

course of earth's long history." (Talkorigins.com)The discoverer of evolutionary theoryCharles

branches of the tree and the old creations fall away like dead limbs. Darwin's analogy went into

Charles Darwin's Theory of Evolution Essay
Before the theory of evolution was a widespread theory in the world of science, Greek and Roman
philosophers had their own theories about how life came to its present state and where it was
going from there. One theory at the time was that all organisms are reflections of a "perfect" form
and were coming closer to it all the time, although this was the less accepted theory even though it
was closer to the truth proven hundreds of years after, while another was that all things were simply
places on Earth in their present form, common to modern day Creationism. Even after this, Darwin
was not the first to try explain evolution, he just provided convincing proof and published his ideas.

While on the GalГЎpagos Islands, Darwin kept notebooks about all the species there, and he
noticed the variety of tortoises on the island who were essential in explaining his theory of
evolution. There are several species of tortoise present on the GalГЎpagos Islands that are all very
closely related, but slightly different. There are eleven presently surviving subspecies of
GalГЎpagos tortoises; furthermore, six of the eleven are found on different islands in the
archipelago, and the other five are all found on a single island on five separate volcanoes with their
own mini–ecosystems (PNAS). Although all of the species of GalГЎpagos tortoise is different, they
each have small differences that can include maximum adult size, shell shape, and the length of the
neck and limbs. The tortoises of the islands are most closely related to the Chaco tortoises along the
western coast of South America, and they most likely came to the GalГЎpagos by "rafting" across
the water (PNAS). Similar to the tortoises, Darwin observed that the Finches on the islands also had
changed to match the environment. Spread among the islands were fourteen subspecies of finch

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

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

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

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
