Genetic Genealogy
The fact that Y-chromosome DNA (Y-DNA) is paternally inherited enables patrilines, and agnatic kinships, of men to be traced through genetic analysis.
Y-chromosomal Adam (Y-MRCA) is the patrilineal human most recent common ancestor, from whom all Y-DNA in living men is descended. Y-chromosomal Adam probably lived between 60,000 and 200,000 years ago, judging from molecular clock and genetic marker studies.

Famous quotes containing the word genetic:
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
