Essay On Human Evolution

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 which

The Pros And Cons Of Human Evolution
Human Origin has been an argument that I have heard about when I was in public school. I learned about evolution at school and creation at home. I
was never able to really argue for creation until coming to Southeastern University. I also never paid attention in class when we were learning about
evolution because I knew that I did not believe it. Learning a lot in this class and others, now I believe that I would be able to start a conversation
with people who believe in evolution and be able to stand up for what I believe in.
Merriam–Webster says the definition of evolution is, "descent with modification from preexisting species: cumulative inherited change in a population
of organisms through time leading to the appearance of new forms: the process by which new species or populations of living things develop from
preexisting forms through successive generations."1 Science says that humans are descendants of apes. So, we are related to chimpanzees, gorillas, and
orangutans also. Human evolution (anthropogenesis) is the part of biological evolution concerning the existence of Homo sapiens as a distinct species
from other hominins.2 Science says that the homo genus diverged from the australopithecines about 2 million years ago in Africa.
Science says that we are closely related to apes because our genomes are 98% identical. If you think about it though, 1% is a huge difference when
you consider that the genome is 3 billion base pairs. So, in just a 1% difference, there are 30

The Evolution of Humans Essay
The Evolution of Humans The evolution of humans was (and is) a very important time. The first being of evolution was Australopithecus Afarensis or
"Lucy". Then we moved on to Homo erectus and Homo Neanderthal. When the weather got hotter, we were Homo Sapiens Sapiens and finally, the
modern man. This evolution did not happen overnight. It took millions of years. The past is hardly forgotten, but the imminent is next. The future of
evolution is being studied as well as the past. Most people were skeptical of the idea that humans are not a perfect species but scientists all over the
globe have made some shocking discoveries. Now that humans have researched the past changes, we can assume the future of evolving humans. We
can tell we are...show more content...
The evolution of humans took a very long time but it was all in good reason. The Australopithecus Afarensis was the first "man". The "Lucy" (another
name for Australopithecus Afarensis) was an ape–like creature that roamed for a few million years and was first to discover food. Lucy was first of
many but had the most struggles. The animal starved until it ate and had to learn from trial–and–error. If the orange berries made you sick, you didn't
eat the orange berries. If the sapling that has red fruits gave delicious food, then you ate that red fruit. Meat did not come until the Neanderthals starved
for any type of food so they hunted. Then came the Homo erectus which is pretty much a Lucy with less hair. The evolution occurred due to too much
hair making Lucy hot. The Evolution was also for the ice age. But as the ice thawed, we evolved into the Homo Neanderthal, or Neanderthal. The
Neanderthal was a Homo erectus with even less hair than Lucy. The Neanderthal was the being that created tools and changed life on earth. Forever.
When the Neanderthal created tools, houses came along pretty fast. When the house came along, the need to climb trees became less and less. After
the need to climb trees was unnecessary, the need for long, climbing toes became useless and so, the long, climbing toes turned to short, stubby toes.
Afterwards, the Homo Sapiens Sapiens came along which no big deal. The beings where just shedding hair that never grew back. When the hair was
lost,

Homo Sapien Human Evolution
Charles Darwin stated that the evolution of man would take not thousands of years but millions of years. In the case of the human species (Homo
sapien) evolutionary theory posits that this has been the case. Human evolution begins with the primate lineage which also includes new and old world
monkeys, and apes (Phelan, 2015). It is important to note that researchers have determined that the chimpanzee is the humans closest living relative.
While, humans and chimpanzees have similar genetic and anatomical structure which signifies a close evolution relationship, it is also important to
note the anatomical differences that distinguish Homo sapiens. Unlike chimpanzees, humans evolved toward bipedalism, grew larger brains and
eventually became bigger in size (Phelan, 2015). As Darwin suggested human evolution has branched down for millions of years and thus has many
significant events that result in the human beings that we are today....show more content...
The fossil of one of the species known as Lucy was found on November 24, 1974, at the site of Hadar in Ethiopia (Arizona State University , n.d.).
Lucy, a three million plus year old hominid female shed light on the life and evolution of Australopithecus and Homo animals. Next, the Homo
habilis appeared as the first species that was bipedal and had a larger brain volume than the chimpanzee (2015). This species also had smaller teeth.
Stone tools found by archaeologists suggest that the Homo habilis may have been the first species to use more civilized methods for food preparation
(2015). The Homo habilis quite possibly gave rise to the Homo ergaster who begot Homo Heidelbergensis, who begot the Homo sapien (Smithsonian

Essay about Evolution of a Man
Evolution is a slow, tedious process that has been going on for thousands of years. Evolution can happen in places such as the world itself, in plants
and animals, and of coarse in the human being. In a specific case of evolution a man named Macbeth went through some drastic, life changing events
that caused him to evolve into a different person. Macbeth evolved from being a moral man who was very hesitant to murder his cousin to a reckless
murderer who would kill anyone who crossed his path. Macbeth had a terrible hunger for power, a ongoing paranoia, and the idea that he had gone too
far with his murders that he could never turn back, all these factors contribute to Macbeth' s slow evolution to an out of control murderer.
Macbeth...show more content...
Macbeth wants so desperately to remain king that he begins to kill anyone and anyone who may pose as a possible threat to his reign. Macbeth became
so blinded with his power that he ended up killing innocent people without the slightest though of regret.
After Macbeth killed his cousin Duncan he became overwhelmed with guilt and paranoia. Shortly after Duncan's death Macbeth stated how he couldn't
wash the blood off his hands, which shows his original reluctance to this murder. After time however, Macbeth's state of mind began to go into a
sheltered almost mad paranoia, which drove him to commit a number of unnecessary, reckless murders.
Macbeth evolves into a reckless murderer in one other very important way, he felt that he had no other option. He is quoted saying that he was in
too deep in the river of blood to ever turn back. This statement obviously shows how Macbeth felt helpless to this situation, he felt that his fate was
locked into place and no matter how hard he tried he could not change the fact that he had become an uncontrollable murderer. Macbeth felt as if he
was in too far over his head and fro every time he murdered someone else he waded deeper and deeper into this so called river of blood.
Evolution is a process that has been occurring for thousands of years, evolution of the planet of the creatures living on it and most importantly the
species we have come to call man. These forms of

The Evolution of Man
Everything as we know it all started with a bang literally, it formed planets, stars, and even life forms. When it comes to mankind however, we are
relatively new to the universe despite most people's beliefs that the universe revolves around us. Without bringing religion into the mix, "all people
originated from apelike ancestors and evolved over a period of approximately six million years"(human origins) which is quite some time compared to
our life span. As we evolved we adapted and became smarter and better able to survive. Survival of the fittest did not appear to be the case, the more
we evolved, the more over populated the world became. So what have we over come as a species, and where are we heading for the future generations?

Each tribe knew with justification that if it was not armed and ready, its very existence was imperiled"(discover magazine). Through competition
with each other, we as a species have been driven to adapt and evolve to overcome struggles that past generations have failed at. It's also led to the
growth of our cognitive skills, most inventions that we have created are either heal or war related. Once again group selection is pushing us to
create something bigger and better than the last technology to overcome the obstacle in front of them. Others have also theorized that our lust for
battle is also an unconscious urge to regulate the population. If we never had wars, by now our population would be in the trillion and we would
never be force to evolve either. Not only has war forced us to evolve, but also has disease. Over the millions of years we have occupied the earth

have faced the Black Plague, yellow fever, malaria, and that's only the tip of the metaphorical ice berg. As each of these diseases have hit man kind
we have adapted and built immunity as well as a wide range of medical advance's that have mostly come to light with in the past thousand years or so.
These immunities have come to pass because once a human has become immune they pass it to their

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 offossil 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

The greatest mysteries of science, a subject which intrigues us all is how exactly the human species evolved. Evolution is the sequential process of

The increase in the earth's temperature may have meant long dry seasons, at which time a lot of the vegetation by which it is thought their diet
mainly consisted of, would have dried up. The herbivorous animals living on the plains would have also struggled to find food and the majority
would have died out. In the late Pliocene era one line of the Australopithecines began to develop a larger brain, this could be due to increase in protein
from the change to a more meaty diet. Fossils of these hominids are sufficiently human–like; they are classed in our own genus, Homo the best known
specimens of this line are the Homo habilis stone tools began to appear, giving us the first direct archaeological evidence of behaviour. Australopithecus
boisei is the greatest in size of all the australopithecines. It was the largest of the australopithecines and it had developed larger teeth and jawbones. The
Advanced Australopithecus is distinguished from the other australopithecines due to its advanced features such as greater intellect. Many scientists feel
that this australopithecine should be regarded as the 'true man.' They also call Advanced Australopithecus "Homo habilis." nevertheless; Homo erectus
is now classified as the first true man. Homo erectus contained a more primitive brain, which had a cranial capacity to half the size of Homo sapiens.
In addition, Homo erectus led

The Importance Of Human Evolution
Evolution is the idea of similarities among organisms the indicate a common ancestor from which all species link back to. Michael Park states that
"Different species exist because, in the continuous process of adaptation, species can and do give rise to new species. Environments to which species
are adapted are always changing (Park, 47)." Human evolution is the process of humans changing from primate ancestors to what is now modern–day
homo sapiens. The shared DNA could have shaped our individual susceptibility to modern day diseases or adaptation to new environments and
climates. Evolutionary history does violate how humans see themselves in the modern world. However, I believe this is a natural part of evolution that
is brought about by the long–term evolution of a single species. In his book park explains this idea through the idea of adaptation stating that "Each
living species has its own unique set of adaptations to its own unique environmental niche, and these can be described (Park ,48)." The way humans
view themselves is part of the process of evolutionary history itself the modern worldview is a by–product of our evolutionary history. Park states that
"In fact, we are unique in that we can consciously change certain behaviors if they are not giving us the desired results (Park, 49)."
Evolution at its core is a change in a species behavior or physical features to adapt and survive in their environment. However, humans are different
as were highly advance humanities views change based on the time we live rather than biological needs like other animals. For example, one of the
biggest parts of evolutionary history that violates modern human views is our current diet and an overabundance of food. For most of our evolution,
the only foods humans could eat were those things directly accessible in their local environment, animal or plant. We ate, farmed and cultivated only
what we needed to survive and evolved and change accordingly like, for example, our teeth and face to meet those dietary habits. Humans have no
longer evolved to better solve their food means rather a technology has involved creating food manufacturing, and cold storage, which allows almost
any food from any part of the world is

The next major species found after the Australopithecus was the Homo habilis. Around the same time period they came into existence, two other
species were present, homo rudolfensis (Alexeev 1986) and homo ergaster (Archaeology Information n.d). The brain size of Homo habilis was about
590–687 cc, unlike the Australopithecus they should evidence of tool usage (Tobias 1987).
The homo ergaster species has a brain size of approximately 860cc (Australian museum n.d). They also showed evidence of tool making and there
was a possibility of vocalization (). It is evident through this how the species are becoming more and more progressive, from the first species
discussed not showing evidence of tool making and their brain size getting larger as each species is evolving. The next set of species is the homo
Neanderthalensis; they evolved from a species named homo Heidelbergensis, who were thought to be the first species that acquired protolanguage (de
Beaune et al. 2009). Homo Neanderthals had a brain size was about 1100–1400 cc (Holloway, Sherwood and Hof et al 2009). They showed evidence of
tool usage; they were able to cope with frequent and dramatic changes in climate/ scenery () This shows that they were more able to adapt to
environmental changes than the previous species discussed.() The Neanderthals first showed evidence of burial of the dead with gifts and also care
for the elderly; this is an indication of social and cognitive abilities as they were able

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

The Evolution of Humans One of the most astonishing things on earth is the human body. They consist of many organs that work together to maintain
the person alive. The humans body composition is complex, but what was the origin? How did we become who we are today? These are the questions
that intrigued me, and allowed me to understand how the human body evolved over the years. By the examination of our ancestors, and our body we
will understand how we look today. Human evolution is "the process by which human beings developed on Earth from now–extinct primates" (Human
Evolution, 2017). It is thought that human evolution began with a species of ape called Australopithecus, or one referred to as Neanderthals. These
species most closely resemble the beginning of humans because they were a type of ape that walked up–right. As time progressed our primates began
to adapt to the environment, and slowly changed into who we are today; Homo sapiens. Charles Darwin– an English naturalist, geologist, and
biologist–was known for developing the theory of evolution. He explained that evolution was a "decent with modification" (On the Origin of Species,
1859). This meant that we all originated from a different species. However, we do not look exactly alike because we adapted to the environment we
were exposed to. Although we all originated form a certain species, after undergoing serval mutations throughout generations to ensure

The Evolution of Human Mating
It may seem obvious to some why people mate, however there are many facets to human mating. Psychology has shown that reasons for mating have
gone beyond the scope of love and physical attractiveness. People may search for mates who resemble archetypical images of the opposite–sex parent,
mates with characteristics that are either complementary or similar to one's own qualities, or mates with whom to make an exchange of valuable
resources (Buss 238). Although these theories play a key role in understanding patterns in human mating preferences, evolutionary psychology and

Consequently, in short term relationships it has become an active part of a man's repertoire. One strategy that has evolved as a result of this problem is
for males to lower their standards in looking for an acceptable mate. Such standards include age, intelligence, personality traits, and status (whether or
not she is involved in another relationship). Another strategy that has evolved is to limit the time it takes to seek sexual intercourse from a woman.
More time spent on seeking sexual involvement from one female, the less time that can be spent on making another effort for sexual intercourse from
another. Men prefer to spend the least time, energy, and resources in making a short–term relationship successful. It is for this reason that they look for
sexual accessibility. A man's strategy for solving the problem of sexual accessibility is to look for sexual experienced women. Often men concur
promiscuity to be one sign of experience. They steer away from women who seem prude, conservative, or have a low sex drive. Fertility and
reproductive value are high on the list of important qualities in a short–term mate. Fertility is the probability of present reproduction. Reproductive
value refers to expected future reproduction. Therefore, a younger women would have higher reproductive value that an older female because her
reproductive future is longer whereas the older women has a higher fertility value than the

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.

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,

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

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 thatnatural 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.

Physical And Cultural Effects Of Human Evolution
Humans have ruled this world for thousands of years, being with Homo sapiens. Before man was able to stand and think he was no better than a
monkey. A beast born of nature, destined to only survive and not live a life of thought and choices. This burden fell on man through millions of years of
evolution. To better understand human evolution this essay will look at some of the physical and cultural effects of evolution on man. Such as the
overall definition of evolution, human evolution from apes, human genetic diversity, cultural anthropology, and the cultural phenomenon that comes
with evolution. The textbook defines evolution as a change within a species over time and have a common ancestry. Webster defines evolution as,
cumulative inherited change in population of organisms though time leading to the appearance of new forms. These definition mean that over long
periods of time genetic mutation develop in a species and these new traits are passed down through birth. One great depiction of this concept is Fig
3.5, introducing anthropology, showing the idea of how giraffes evolved. The idea of giraffes as we know them today came from herds of much
smaller neck animals. The ones with longs necks possibly were able to eat the ever taller plants and because of this they survived and produces more
and more offspring that would have this same trait of long necks, until no short necks were left. This concept can be applied throughout evolution.
Animals must adapt to survive and

Evolution Of Human Evolution
The study of Anthropology has numerous fields including paleoanthropology or the search of fossilized remains of humanity's ancestors.
Paleoanthropology can help explain the theory of evolution. Evolution is the theory proposed by Charles Darwin and argues that organisms change
physically over time. Part of Darwin's theory of evolution is the idea of natural selection. Darwin also stated that organisms must have a common
ancestor. The theory of human evolution is that humans evolved from primates. Paleoanthropologists can compare remains to understand show how
humans or hominids evolved.
The evolution of hominins first began in African between 10 to 5 million years ago. The adaptation which set hominins apart from hominoids or
other primates was bipedalism. Bipedalism is the ability for species to walk on two legs instead of four. Bipedalism is an example of natural
selection. While the skeletal structure of primates allows them to stand on their hind legs for short periods, the ability to stand on two legs provided
many advantages for early hominids. Bipedalism allowed the hominids to survive and reproduce. Since bipedalism was a practical adaptation, this trait
was passed down through the different species of hominins. While the reason hominin became bipedal is unknown various theories have been
proposed. Theories suggest the humans became bipedal to adapt to climates affecting our ancestor's ability to gather food. The theory states that the
climate in the caused

Man is a creation of evolution. Therefore, human evolution is closely related to the origin of life and its development on the earth. It is normal to
speak of evolution 'from amoeba to Man', as if the amoeba is the simplest form of life. But, there are several organisms more primitives than amoeba,
say for example viruses. The evolution from a self–replicating organic molecule to a protozoan, like amoeba, is the most complex step in evolution,
which might have consumed the same extent of time from protozoan to man.
About 10 billion years after the formation of Universe, the earth was formed. Life on earth appeared far late, nearly three billion years ago. Of the
several evolutionary problems, perhaps the origin of life is the most critical, since there is no record concerning it. Life has been characterized by the
capacity of performing certain vital functional activities like metabolism, growth and reproduction. There is no doubt regarding this point. But how the
first life came on earth is a matter of conjecture.
Darwin's theory of evolution
The theory of evolution by natural selection, first formulated in Darwin, is the process by which organisms change over time as a result of changes in
heritable physical or behavioral characters. Changes that allow an organism to better adapt to its environment will help it survive and have more
offspring. Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a

Every piece of evidence that have been found through the years points at Africa as the birthplace of Man. Scientifically proven is that these early
humans migrated to the rest of the world was due to environmental factors and the ability to adapt to these changes.
In the Movie The Real Eve shows the scientific study of the mitochondria DNA that can be trace back to one single woman from Africa. This to me
is another evidence in providing where we come from. The study reveals the mitochondria DNA of different African people and that of Europeans.
The mitochondria DNA of Africans showed that they were different thus proving how they migrated to other parts of the world while those of
Europeans remained the same. This scientific revelation to the study of man once again explains our roots where in Africa. Early humans did in fact
come from Africa and migrated to the rest of the world when the environment allowed them to and when their survival rate began to decline due to
food or shelter. Homo Sapiens according to archeologist first were four legged animals with one third of the brain as that of humans today. Through
evolution these four–legged animals evolved into two legged humans with a larger brain. The two–legged humans were able to make tools and
weapons with their newfound free hands. The changes that occurred according to the book the History of Africa we descended from Homo Habilis
