Vedclass · Answer

(D) The 'Out of Africa' theory is supported by genetic evidence,specifically mitochondrial $DNA$ $(mtDNA)$ studies. Because humans originated in Africa and then migrated to other parts of the world,the African population has had more time to accumulate genetic mutations. Consequently,$DNA$ studies show that there is greater genetic diversity (variation) among populations in Africa compared to populations in other regions like Asia or Europe. This higher level of genetic variation in Africa is a key indicator that modern humans originated there.

There are two conflicting views regarding the origin of modern humans. One view suggests that $Homo$ $erectus$ in Asia were the ancestors of modern humans. However,studies of $DNA$ variation suggest that modern humans originated in Africa. Which type of $DNA$ variation indicates this?
