The Debate Over the Origin of Modern Homo Sapiens Essay example -- Ant

The Debate Over the Origin of redbrick humanity Sapiens There has been a great deal of heated reason for the last few decades about where modern gentleman sapiens originated. From the engagement grounds, two main theories emerged. One surmisal, labeled Out-of-Africa or population exchange explains that all modern Homo sapiens evolved from a common Homo erectus ancestor in Africa 100,000 years ago. The species began to disperse and replace all other(a) archaic human-like populations around 35,000 to 89,000 years ago. The rivaling opinion, entitled the regional continuity surmisal or multiregional evolution model refutes this hypothesis and states modern humans evolved from unlike species of Homo erectus who interbred with others that lived in places such as Asia, Africa, and Europe. These scientists believe this theory would explain why there are differences among races around the world. As vowelise as the regional continuity theory appears, it seems to be sligh tly absent in genetic embolden. It appears that most of the support of this theory depends on dodo record which is important information but not stable evidence. The Out-of-Africa theory relies on more than just fossil evidence but a combination of fossils and genetic studies. It is important to use this information as well as the fossil records because various interpretations of the transition are possible if researchers focus on on only fossil evidence, while the mtDNA studies more strongly support replacement.the best approximation of the process still appears to be an African-based spread (Nitecki and Nitecki, 1994). In a time where technology is becoming an integral recrudesce of society, it is easier to discover information that did not seem possible before. ... ...and Matthew Nitecki, eds. (1994).
