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.
