Y-chromosome Adam
In human genetics, Y-chromosomal Adam (Y-MRCA) is a hypothetical name given to the most recent common ancestor (MRCA) from whom all currently living people are descended patrilineally (tracing back only along the paternal or male lines of their family tree). However, the title is not permanently fixed on a single individual (see below).
Y-chromosomal Adam is named after the biblical Adam, but the bearer of the chromosome was not the only human male alive during his time. His other male contemporaries could also have descendants alive today, but not, by definition, solely through patrilineal descent.
The age for the Y-MRCA has been variously estimated as 188,000, 270,000, 306,000, and 142,000 A paper published in March 2013 reported an older estimate of 338,000 years. Then two simultaneous reports in August 2013 provide younger estimates, one suggested 180,000 to 200,000 years, and another, based on the genome sequence of nine different populations, indicated the age between 120,000 and 156,000 years.
Analogous to Y-chromosomal Adam, Mitochondrial Eve is the woman from whom all living humans are descended matrilineally, who lived about 140,000 to 200,000 years ago in Africa. The estimate is based on inherited mtDNA though mothers. Theoretically, it is not necessary to believe that Y-chromosomal Adam and Mitochondrial Eve should have lived at the same time. However, latest findings in 2013 give the possibility that the two individuals could be contemporaneous.
