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:
“We cannot think of a legitimate argument why ... whites and blacks need be affected by the knowledge that an aggregate difference in measured intelligence is genetic instead of environmental.... Given a chance, each clan ... will encounter the world with confidence in its own worth and, most importantly, will be unconcerned about comparing its accomplishments line-by-line with those of any other clan. This is wise ethnocentricism.”
—Richard Herrnstein (1930–1994)
