Exactly where did Contemporary Humans originate and how are they unique from their archaic ancestors?
Contemporary Humans or Homo sapien sapiens origination is a query of controversy and much debate within the scientific neighborhood. In this essay I will attempt to illustrate the most significant theories and supporting proof as properly as make inferences about how they differed physically, socially and culturally from their archaic ancestors.
There are two major theories regarding the evolution of Contemporary Humans, the 1st is the “Replacement Theory” and the second is the “Continuity Theory”. The Replacement Theory infers that Contemporary Humans evolved in Africa from Archaic and “Pre-Modern” Homo sapiens, terms describing a diverse variety of Humans which lived from prior to 150,000 years ago to possibly significantly less than 10,000 years ago (McBean, 2002) and that this new species radiated into South East Asia and then out into the rest of the globe via land bridges. The Continuity Hypothesis suggests that the evolution of Homo sapiens did not necessarily take location in Africa but in other places of the globe, evolving independently of each and every other.
Up until the 1980’s most of the info that we had on the origination of Contemporary Humans came from the fossil record. In 1987 a Biochemist at the University of California, Berkeley named Allan Wilson concluded that Homo sapiens are an entirely new species that originated in Africa alone (the Eve hypothesis). The Mitochondrial DNA mapping of Rebecca Cann in 147 humans also points towards greater diversity in the African group than any from Europe, Asia and New Guinea. Anthropologists stay divided more than the theory. Some consider a migration of conquering humans from Africa to be at odds with the fossil record. (Wolpoff, Thorne and Lawn, 1991). Also on statistical grounds and mainly because the information is nonetheless inadequate to reject the multi regional (Continuity) hypothesis fully (Fagan, 2004).
What we do know is that the oldest Modern day Human fossil remains outside Africa (Anon, www.ecotao.com). A 200,000-year-old Homo sapien skull was identified in Dali, China. A different Modern Human fossil was found in Qafzeh, Middle East and is one hundred,000 years old. Whereas Homo sapien sapiens fossils that have been excavated at the Klasies River Mouth and Border Cave in South Africa date involving 60,000 and 80,000 years old.
Even though it is not clear precisely where Contemporary Humans originated it is clear that if the Replacement…
