"200,000-year-old Eve" by Stephen M. Miller
AFRICAN EVE. Humanity’s mother lived in Africa some 200,000 years ago, according to many geneticists relying on DNA studies. By that time, something geologists call “the Wall of Africa,” a 3700-mile (5955 km) stretch of hills and mountains from Ethiopia in the northland to South Africa at the continent’s southern tip, rose and began blocking the ocean moisture. That let jungles and thick forests dry into a patchwork of woods and fields more suitable for humans. Art by Jerry Feist, flickr, CC2.
SCIENTISTS WHO STUDY HUMAN GENETICS say all humans today likely descended from one woman they call Mitochondrial Eve. “Mitochondrial” refers to a type of DNA that’s passed on from mother to child with genes that rarely change.
Geneticists estimate that “mtEve,” as they’ve nicknamed her, lived about 200,000 years ago, possibly in East Africa.
This dating is based partly on assumptions from modern tests that compare the likenesses and differences in the genes of random blood donors. Geneticists say these tests allow them to determine the degree to which any two donors are related to one another.
Scientists then converted the relatedness of random people to a measure of time, backtracking nearly a quarter of a million years to what they say was the mother of today’s human beings.
Many Christians say they don’t buy the theory and argue that genealogies in the Bible put Eve at about 6000 years ago. Other Christians say Bible genealogies are only partial and that the scientific study is intriguing.
