The Evolution Of Humans And Humans - 978 Words

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is Lucy, an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens. The Australopithecines were the first to walk upright, or became bipedal, although rather clumsily. Their walk was unsteady, judging by their bone structure (Figure 1.), and they most likely were quadrupedal the majority of the time. The Australopithecines had a brain about the size of an orange, high up cheekbones, and big molars. They were about three feet tall, and had small thumbs. Australopithecines, while definitely possessing some human characteristics, humans are still much closer to the chimps. Australopithecines were vegetarians; even if they knew that animals were edible, they still had no reliable means of killing animals for food. About 2 million years ago, highly evolved Australopithecines made theShow MoreRelatedThe Evolution Of Human Evolution1103 Words   |  5 PagesHuman evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable a ffinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a commonRead MoreEvolution of Human3142 Words   |  13 PagesHuman 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 aboutRead MoreHuman Evolution And The Human Race Essay1126 Words   |  5 Pagesof an earlier work written for this class. I feel there is room to no t 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 thatRead MoreHuman Evolution2755 Words   |  12 PagesHuman Evolution Human Evolution, the biological and cultural development of the species Homo sapiens, or human beings. A large number of fossil bones and teeth have been found at various places throughout Africa, Europe, and Asia. Tools of stone, bone, and wood, as well as fire hearths, campsites, and burials, also have been discovered and excavated. As a result of these discoveries, a picture of human evolution during the past 4 to 5 million years has emerged.

What types of studies are conducted and have these studies changed in recent years? Why or why not? We study nonhuman primate behavior to help us better understand us as humans and our behavior compared to nonhuman primates. Clearly there are differences in behavior among different species of primates - especially humans.

Many specialized in their respectful field. Move toward together to get a world view of human life. History is a word that is always driven out, to look back at a period of time and one might compare the pervious time to the present. It’s vital for us mortal to understand where came from and where we are going. Since history often does repeats itself, it may be good, to look backwardsRead MoreEvolution And Its Impact On Human Evolution910 Words   |  4 Pages 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 evolutionRead MoreEvolution And Its Effect On Human Evolution1826 Words   |  8 Pages It is the key to our evolution is very much correct. Beneficial mutation can be a next step of human evolution as people get more adapted to their environment, greatly increasing their chance of successfully reproducing. Evolution is the process of the characteristics of an organism changing over a long period of time. There are two types of evolution: micro, where gene frequencies are shifted within the population, and macro, where a whole new species arises.

It is the ability to digest milk in adulthood, conferred by genetic changes that occurred as recently as 3,000 years ago, a team of geneticists has found.The finding is a striking example of a cultural practice — the raising of dairy cattle — feeding back into the human genome. It also seems to be one of the first instances of convergent human evolution to be documented at the genetic level.

I believe based on the evidence and the different articles that it is a new species. If that truly is the case, then that is amazing to even think about. There is dissimilarity within species; there are also discrete species. The term hominid is a member of the zoological family Hominidae. Hominidae incorporates all species instigating after the human/African ape familial divided
