Human evolution is the origin and evolution of Homo sapiens as a species that can be distinguished from other hominids, great apes, and mammals. Neanderthals are a unique species as they can be either classified as a subspecies of Homo sapiens as Homo sapiens neanderthalensis, or can be classified as a distinct and separate species as Homo neanderthalensis. Though Neanderthals are presently considered an extinct species, evidence indicates that H. sapiens and Neanderthals, at one point, mated with each other, human evolution essay. It is believed that Neanderthals inhabited Europe and parts of western and central Asia as far back astoyears ago. Evidence that Neanderthals and H. sapiens coexisted was discovered in France and Israel. Further investigation and analysis of fossils found in these areas indicate that Neanderthals, as well as H.

Accessed 4 May Retrieved from. Human Biology Human Evolution in Africa The human evolution in Africa is a drawn out process of transformation by which natives' originated from the apelike ancestors. Scientific study shows that behavioral traits and physical traits shared by the people came from the apelike ancestors over approximation of six million years ago.
The earliest traits were the bipedalism is walking using the two rear limbs. Other human trait was the ability to make and use tools by using their own intelligence, and capacity for the language developed recently Philip Human evolution has been used to show how humans originated and how they adapted to situations many human evolution essay ago. It was argued that the human evolution stopped due to humans implications towards the environment, human evolution essay. The adaptive responses were serious implications of infectious diseases.

How humans Evolved. New York: Norton. McHenry, H. Cambridge, Massachusetts. This postmodern view of culture is applicable in the 20th century analyses and discussions introduced by oyd and Richerson. In effect, the first assumption explicates how culture brings forth history, and in history, "qualitative different trajectories" occur: " the dynamics of the system must be path dependent; isolated populations or societies must tend to diverge even when they start from the same initial condition and evolve in similar environments" After establishing the potential, crucial role that culture and generally, history, plays in the human evolution, oyd and Richerson then explicated on the interdependence of science and culture in the evolutionary process.
The authors posited, as mentioned earlier in the introduction, that culture induces the evolutionary process in the same way science does. According to the authors, evolutionary process is influenced by "cultural analogs," enumerated as random forces, natural selection, and decision-making forces, human evolution essay.

The results of such research are remarkable and at the same time contradictory, human evolution essay. Apparently, according to research conducted, although people have evolved in terms of eating habits, resources available, and living conditions, these evolutions enable them to sometimes use the results to change the human in itself, for instance through the choice of DNA and the desire for perfect traits to improve the next generations Shute, At the same time though, the discovery and research of DNA has enabled human kind to avoid the reproduction of mutations and to overall provide a better quality of gens for people. Given the rapid growth of the population by comparison to 10, years ago, these changes are significant because they….
Africa" to "Out of Beringia": Can Population Genetics Explain the Mechanisms underlying the formation of Distinct Cultures and Linguistic Groups? According to this theory populations of anatomically modern H. sapiens humans left the African Continent sporadically over a period of 10's of thousands of years and these outward migrations constitute the genetic origins of all non-Africans. The results from these studies in world population genetics paint a fascinating history of our species' gradual and sporadic entry into the rest of the world, a history that only a few decades ago was more theory than fact. The "Out of Africa" theory gained support when researchers compared genetic markers in the mitochondrial DNA mtDNA from Africans and non-Africans. References Campbell, M.

Cultural and Climate Effects on Human Evolution Human evolution essay group selection's contribution to the progression of cooperation among humans is intensely contested.
A majority of human behavior impacted by culturally diffused philosophies including religious views does not seem adaptively sensible. hether or not strong socio-biological reasons are available for explaining such behavior marks the focal point of arguments between sociologists and critics of sociology. There are, in theory as well as possibly in fact, several instances, which combine aspects of both.
