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

The Debate Over the Origin of Modern adult male sapiens There has been a great deal of heated debate for the give out few decades about where modern Homo sapiens originated. From the battle grounds, deuce main theories emerged. One theory, labeled Out-of-Africa or population renewal let offs that totally modern Homo sapiens evolved from a common Homo erectus ascendant in Africa 100,000 years ago. The species began to spread and replace all other obsolescent human-like populations around 35,000 to 89,000 years ago. The rivaling opinion, entitled the regional continuity theory or multiregional evolution model refutes this theory and states modern humans evolved from various 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 sound as the regional continuity theory appears, it seems to be slightly lacking in g enetic support. It appears that most of the support of this theory depends on fossil go into 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 concentrate 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 technical schoolnology is becoming an integral part of society, it is easier to keep information that did not seem possible before. ... ...and Matthew Nitecki, eds. (1994).
