Y-chromosomal Adam - Wikipedia

Secular geneticists believe that modern humans can trace their male genetic ancestry back to a single man and their female genetic ancestry back to a single woman.1 Two new studies suggest that female "mitochondrial Eve" lived at roughly the same time as "Y-chromosome Adam." However, the assumptions they used to reach this dating concordance demonstrate the classic circular reasoning that
