Question

Evidence of the Single origin hypothesis (mtDNA)

Answer 1

Mitochondrial DNA provides evidence for the single origin hypothesis of modern humans, suggesting that all modern humans have a common ancestor that lived in Africa about 160,000 years ago.

Step-by-step explanation:

Mitochondrial DNA (mtDNA) provides evidence for the single origin hypothesis of modern humans. mtDNA is passed down entirely through the maternal line and mutations in mtDNA can be used to estimate genetic divergence. Studies using mtDNA suggest that all modern humans have a common ancestor that lived in Africa about 160,000 years ago.
