How do we know mitochondrial Eve is every human's ancestor?

Question

Quizplus · Accepted Answer

Mitochondrial Eve is the most recent common ancestor of all living humans, traced through the maternal lineage. Mitochondrial DNA is passed down from mothers to their offspring without recombination; therefore, the analysis of global comparison of human mitochondrial and nuclear sequences has shown that all humans today have inherited their mitochondrial DNA from a single woman who lived about 200,000 years ago in Africa, making her the most recent common ancestor of all humans. This evidence supports the theory of human evolution from Africa. Option A is incorrect as mitochondrial DNA is passed down maternally, not through males. Option B is incorrect because it does not directly address mitochondrial DNA. Option D and E are incorrect as they refer to specific geographical regions and time periods, whereas mitochondrial Eve represents a global and ancient human ancestor.
