en.news All human beings who live today descended from a solitary pair [viz. Adam and Eve] who lived 100,000 to 200,000 years ago.
This is the result of a research conducted by Mark Stoeckle (Rockefeller University, New York) and David Thaler (University of Basel).
They surveyed snippets of DNA that reside outside the nuclei of living cells (genetic bar codes) of five million animals including men.
The result: Men sprang from a single pair of adults after a catastrophic event almost wiped out the human race [viz. flood].
According to Stoeckle and Thaler also 90% of all animal species alive today come from parents that all began giving birth at roughly the same time, less than 250 thousand years ago.
