Y chromosome DNA haplogroup
From ISOGG Wiki
The Y Chromosome Consortium (YCC) has established a system of defining Y-DNA haplogroups by letters A through to T, with further subdivisions using numbers and lower case letters.
Y-chromosomal Adam is the name given by researchers to a theoretical male who is the most recent common patrilineal (male-lineage) ancestor of all living humans. Estimations of the date of this common ancestor have varied significantly in different studies.
