Out Of Africa Theory Essay
Many experts argue over where humans originated from and which human migration and evolution theory is most reliable. With a good hypothesis, factual evidence, and logic, many theories seem plausible. However, there are many holes in each theory (whither it be the out of Africa theory, the out of Australia theory, the out of Asia theory, or the multiregional theory) which leaves many puzzled when it comes to choosing which theory is the most authentic and trustworthy. Out of Africa The “Out of Africa” theory is the most popular and referenced human evolution theory to date. In the “Out of Africa” theory, experts believe Homo Sapiens(modern humans) originated from Africa , including parts of the Middle East, based on anatomical, archaeological, and genetic evidence. Most evidence to this theory was provided by the findings by Rebecca Cann, Mark S., and Allan Wilson. Scholars from the University of California, Berkeley, they created the idea of the Mitochondrial Eve which said

The only reason why DNA is different from person to person is because of mutations. MtDNA , which is “a small circular genome found in those parts of cells called mitochondria.”(Dorothy R. Haskett, October 10th, 2014), is what Wilson, Cann, and Stoneking used to differentiate the populations and pinpoint and learn more about patterns of migrations and where the maternal ancestor for all humans came from since mtDNA is passed down from the maternal parent to the offspring. Wilson and company decided to use mtDNA to find where modern humans arose from since only “a couple of regions preserve the telltale variations[mtDNA]” (James Shveer, March 2006). When the comparison was made with women around the globe (since it is passed down from mothers), it was realized that the biggest variation in mtDNA was in Africa and so it was concluded that all humans have a link to the gene pool in
