Human Evolution Essay
Human Evolution
Human evolution is the biological and cultural development of humans. A human is any member of the species Homo sapiens, meaning "wise man."
Since at least the Upper Paleolithic era, some 40,000 years ago, every human society has devised a creation myth to explain how humans came to be.
Creation myths are based on cultural beliefs that have been adopted as a legitimate explanation by a society as to where we came from.
The science of paleoanthropology, which also tries to create a narrative about how humans came to be, is deeply technical. Paleoantropology is the
science of the evolution of humans, and it is the base of all research in that field. Humans have undergone many different changes during the last

We share almost 99 percent of our genetic material with chimpanzees. Yet we have several traits that are very different. Two legged walking, or
bipedalism seems to be one of the earliest of the major hominine characteristics to have evolved. To accommodate this strange position, we have
developed a specialized pelvis, hip and leg muscles, and an S–shaped vertebral column. Because these changes can be documented in fossil bone,
bipedalism is seen as the defining trait of the sub family Homininae. Much of the human ability to make and use tools and other objects stem from the
large size and complexity of the human brain. Most modern humans have a braincase volume of between 79.3 and 91.5 cubic inches. In the course of
human evolution the size of the brain has more than tripled. The increase in brain size may be related to changes in hominine behavior. Over time
stone tools, and other artifacts became increasingly numerous and sophisticated. It is likely that the increase in human brain size took place as part of
a complex interrelationship that included the elaboration of tool use and tool making, as well as other learned skills, which permitted our ancestors to
be increasingly able to live in a variety of 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. The bones suggest that females may have been 3 to 4 ft in height and

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

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

Essay on The Importance of Human Evolution
Introduction
The main purpose of this essay is to critically discuss the importance of an understanding of human evolution and the history of psychology for the
modern psychologist. The essay aims to critically discuss the study of human evolution which includes some of the species that evolved over the years
before we now have our species, the history of psychology and the different prominent figures that are responsible for psychology being the field it is
today. Finally, how an understanding of this can aid a modern psychologist. To conclude, this essay will collate previous research done onhuman
evolution, history of psychology and the importance of this for the modern psychologist.

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

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

Essay about Human Evolution and Adaptation
Over the course of evolution, humans have evolved to adapt the ever–changing conditions to improve their chances of surviving. Is there still room for
natural evolution or has the time come for us to use our technological innovations and further our development beyond previously thought possible by
biological means. Past trends have shown that as time has passed, significant body structures have changed to counteract the changes to our
environment. The changes that have been most significant are: dentation; brain size; muzzle angles; average body weight, skull structure. Will these
continue to change and progress along similar trend lines, or has the time come for the evolution of our species to become technologically driven?

However as the planet warmed, natural selection may have started to favour a slighter stature in humans. Therefore, as the skeletons and skulls got
smaller the brain shrunk in size as a result (McAuliffe, 2011). Another theory that is circulating the science community is that the decrease in cranial
capacity is attributed to the arrival of agriculture
One theory is that H. sapiens have reached the end of the evolutionary line. As evolutionary changes have occurred, it is known that these changes
become fixed in isolated populations. For example, the Galapagos Finches that evolved from the mainland species to survive in the unique habitat of
the isolated islands. When natural selection occurs, a genetic mutation, e.g. spine suited to bipedal locomotion, is passed through the generations, as it
provides some benefit to the value of life of the organism. Eventually this mutated trait becomes the desired gene for further generations. However if the
populations where these mutations are occurring, the potential for significant mutations to take effect within the gene pool decreases as a result of
interbreeding between populations (Owen, 2009). As H. sapiens have become extremely mobile, as in they can cover large distances thanks to the
development of technological innovations, the possibility between crossbreeding between separate gene pools of different populations, the possibility
that a potentially beneficial mutation can become the desired gene is

Persuasive Essay On Human Evolution
How did Humans evolve? Everybody in the world had asked this question to themselves and to others. It has always been a curious topic for people
to about human creation especially when an individual is young. Some tends to ask parent and nowadays some tents to go on google and search it.
But the results for the answers are different in different cases. Like if an individual would ask a religious parents about creation of humans, they
would get more biblical answer that are related to god [Intelligent Design]. Or an individual could ask this question to a teacher and the answer would
be scientific which has theory and experiments and scientific discoveries [Darwinism]. Or the young individual can be a kid and ask to his/her friend
and get some childish imaginary story. Out of all of this concept about evolution of humans the legal known concept Darwinism. It is taught in all the
publicly funded school because it has non–biased scientific support compared to other concepts. But predictably the people believing in the other
theory like the Intelligent Design also known as I.D. would want publicly funded schools to teach I.D. too with Darwinism upon that some people
wants to replace Darwinism with I.D. in Public schools. The public schools should teach Darwinism because it is scientifically supported by theories
and experiments in spite of the flaws in the theory.
The scientific answer for the human evolution is "Darwinism." It is a theory of biological evolution developed by

Human Evolution And The Human Race Essay
This essay is a continuation of an earlier work written for this class. I feel there is room to not only clarify ideas proposed, but expand and introduce
supplemental ones to further define previous claims. The aim is to propose that though evolution and innovation are incredibly beneficial and important
to the human race, through a series of questionable morals and vast amounts of wrongdoings have created a situation of over–innovation, or innovating
past the point of benefit. Though from a cynical perspective, it is vital that we question what we do. Are we doing what is truly best for ourselves,
our planet, and our neighbors? Or are we striving so arduously that we have essentially skewed right from wrong, and found ourselves in a situation
that humans have lost the sense of morals when it comes to how far we can push innovation?
Innovation is the way that species evolve and ameliorate their means to their ends, whatever that end result may be. Undoubtedly, human evolution is
an impressive trend of wise decision making, trial and error, and frankly luck. To paraphrase a great mind of our time, Richard Dawkins stated that
human creation is a nearly impossible event, and our evolution a rare and improbable one. In fact, our creation is still being proven as more and more
evidence confirms the idea of The Big Bang. This is because of the pure improbability, it's hard to comprehend and come to terms with our creation,
which is why humans have invented ways to cope

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

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,

Evolution And Its Impact On Human Evolution
Humans have gone through many stages of adaptation, allowing for great expansion and our unrivaled dominance of the earth. So it could seem as
though humans have reached the peak of evolutionary development. Evolution is often thought of as a natural process, and were it not for humans, this
might be true. However, evolution, in the strictest sense, is a change in the genetic structure of a population (Jurmain, et al., 5). While natural selection
is a major contributor to the process of evolution, humans are no longer as heavily influenced by these forces, as they once were.
In fact, since the dawn of medicine, humans have actively impeded the process of evolution. By ensuring the survival and reproductive success of those
who would otherwise be considered "unfit," in that they would not otherwise survive. Francis Galton, and others, suggested regulation to control
reproduction, and reduce/eliminate "unfit" characteristics. The eugenics movement led to a number of concerns over what the concept of "fitness"
entails, often prioritizing physical characteristics over beneficial traits (Jurmain, et al., 391).
Even today, and with great understanding of human genetics, concerns exist regarding the ability to control reproduction, and by extension, evolution.
Some early works used genetics as a way to describe how humans differentiated. In one study, researchers sought to reconstruct a history of human
evolution. By combining genetic findings with pre–existing archaeological and

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 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

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

When people take a look at African history in general many topics and ideas come to mind. How the people of Africa lived, how they developed
civilizations and cultures, and how their oral traditions came about are just a few examples. When I am trying to learn about different groups of
people and different areas of the world I most likely start at the very beginning of their existence. Africa being the origin of man and the home for the
majority of developments of early humans suggests that human evolution is an extremely import topic in African history today. Keeping this in mind it

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

Associated with these changes is a gradual 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, the face became smaller and its position changed; thus, the relatively small face of
modern humans is located below, rather than in front of, the large, expanded braincase.
Human Origins The fossil evidence for immediate ancestors of modern humans is divided into the genera Australopithecus and Homo, and begins about
5 million years ago. The nature of the hominine evolutionary tree before that is uncertain.
Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and, later, on the Eurasian continents. Although
many fossil bones and teeth have been found, the way of life of these creatures, and their evolutionary relationships to the living apes and humans,
remain matters of active debate among scientists. One of these fossil apes, known as
Sivapithecus, appears to share many distinguishing features with the living
Asian great ape, the orangutan, whose direct ancestor it may well be. None of these fossils, however, offers convincing evidence of being on the
evolutionary line leading to the hominid family generally or to the human subfamily in particular. Comparisons of blood proteins and the DNA of the
African great apes with that of humans indicates that the line leading to modern people did

Evolution Of Human Evolution
Introduction
The human species has depended on a material culture for millions of years. Without it, humans would not be able to survive. Many people believe that
because we have so many technological advancements and that humans can build or make anything necessary for their survival. Even with the current
technology and other advancements, research has proven that humans are still evolving. Much of the evolution that is happening today has to do with the
human genome and adapting to current issues in the world. There has been much research done on the human genome and how it is still mutating and
changing. Natural selection has a big part in how the genome changes. Mutations are another point to look at when determining if the human species is
still evolving. A third point to look at isgene flow and how that affects different populations. The purpose of this paper is to review multiple different
articles to establish whether or not the human species is currently evolving. The articles used for this paper confirm that humans continue to evolve.
While humans have the technology and skills to make their environments suit their needs, it can clearly be seen that humans continue to evolve and
adapt.

Much later (perhaps 50,000 years ago) hominines were able to cross the water barrier into Australia. Only after the appearance of modern humans did
people move into the New World, some 30,000 years ago. It is likely that the increase inhuman brain size took place as part of a complex
interrelationship that included the elaboration of tool use and toolmaking, as well as other learned skills, which permitted our ancestors to be
increasingly able to live in a variety of environments. The earliest hominine fossils show evidence of marked differences in body size, which may
reflect a pattern of sexual dimorphism in our early ancestors. The bones suggest that females may have been 0.9 to 1.2 m
(3 to 4 ft) in height and about 27 to 32 kg (about 60 to 70 lb) in weight, while males may have been somewhat more than 1.5 m (about 5 ft) tall,
weighing about
68 kg (about 150 lb). The reasons for this body size difference are disputed, but may be related to specialized patterns of behavior in early hominine
social groups. This extreme dimorphism appears to disappear gradually sometime after a million years ago.
Face and Teeth The third major trend in hominine development is the gradual decrease in the size of the face and teeth. All the great apes are equipped
with large, tusklike canine teeth that project well beyond the level of the other teeth. The earliest hominine remains

Did Human Evolution: How Did Humans Come To Be?
How did humans come to be? Human evolution is the lengthy process of change from ape like ancestors to what we are today. One of the earliest
human traits is the ability to walk upright. Another one is having a large complex brain. They are also able to make tools and draw decorative art
figure drawing on cave walls that we are still able to see today. Humans are primates, it shows evidence that homo sapiens have a close relationship
with a group of primate species. Early humans first evolved in Africa and much of the evolution was happening there also. Most fossils of early humans
are mostly found entirely in Africa. Most scientists currently recognize some fifteen to twenty different species of early humans. Most early humans
