In human genetics, the Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the patrilineal most recent common ancestor (MRCA) from whom all currently living humans are descended. He is the most recent male from whom all living humans are descended through an unbroken line of their male ancestors.
6 Αυγ 2013 · Now, two major studies of modern humans’ Y chromosomes suggest that ‘Y-chromosome Adam’ and ‘mitochondrial Eve’ may have lived around the same time after all 1,2.
By tracing the lineages of Y chromosomes back through the stone age, researchers have estimated how long ago humans' oldest paternal ancestor lived. The results support the idea that modern humans originated in Africa, and they help track where humans wandered from there.
6 Μαρ 2013 · Albert Perry carried a secret in his DNA: a Y chromosome so distinctive that it reveals new information about the origin of our species. It shows that the last common male ancestor down the...
The male analog to the "Mitochondrial Eve" is the "Y-chromosomal Adam" (or Y-MRCA), the individual from whom all living humans are patrilineally descended. As the identity of both matrilineal and patrilineal MRCAs is dependent on genealogical history (pedigree collapse), they need not have lived at the same time.
2 Αυγ 2013 · Introducing Y-chromosomal Adam and mitochondrial Eve. Two studies published this week suggest that they might have existed at about the same time, evolutionarily speaking. Here’s Akshat Rathi,...
1 Αυγ 2013 · Mitochondrial Eve and Y-chromosomal Adam — two individuals who passed down a portion of their genomes to the vast expanse of humanity — are known as our most recent common ancestors, or MRCAs. But many aspects of their existence, including when they lived, are shrouded in mystery.
