Scientific Adam and Eve
#3
RE: Scientific Adam and Eve
The answer is just a google away.

Quote:[T]he name Mitochondrial Eve refers to the matrilineal most recent common ancestor (MRCA), in a direct, unbroken, maternal line, of all currently living humans, who is estimated to have lived approximately 100,000–200,000 years ago. This is the most recent woman from whom all living humans today descend, in an unbroken line, on their mother’s side, and through the mothers of those mothers, and so on, back until all lines converge on one person. Because all mitochondrial DNA (mtDNA) generally (but see paternal mtDNA transmission) is passed from mother to offspring without recombination, all mtDNA in every living person is directly descended from hers by definition, differing only by the mutations that over generations have occurred in the germ cell mtDNA since the conception of the original "Mitochondrial Eve".

. . .

Mitochondrial Eve is estimated to have lived between 99,000 and 200,000 years ago,[3][4][5] most likely in East Africa,[6] when Homo sapiens sapiens (anatomically modern humans) were developing as a population distinct from other human sub-species.

Quote:In human genetics, Y-chromosomal most recent common ancestor (Y-MRCA; informally also known as Y-chromosomal Adam) refers to the most recent common ancestor (MRCA) from whom all currently living people are descended patrilineally. The term Y-MRCA reflects the fact that the Y chromosomes of all currently living males are directly derived from the Y chromosome of this remote ancestor. The analogous concept of the matrilineal most recent common ancestor is known as "Mitochondrial Eve" (mt-MRCA, named for the matrilineal transmission of mtDNA), the woman from whom all living humans are descended matrilineally.
By the nature of the concept of most recent common ancestors, these estimates can only represent a terminus ante quem ("limit before which"), until the genome of the entire population has been examined (in this case, the genome of all living humans). In 2013, the discovery of a previously unknown Y-chromosomal haplogroup was announced,[1] which resulted in a slight adjustment of the estimated age of the human Y-MRCA.[2]
Current estimates of the Y-MRCA range around 200,000 to 300,000 years ago, consistent with the emergence of anatomically modern humans and overlapping with age estimates for the mt-MRCA (matrilinear MRCA).[3]
