In human genetics, Y-chromosomal Adam is the name given to the most recent common ancestor (MRCA) on the paternal line of all living males. He was not the only male alive at that time but is the only male whose line has still survived to the present day.

According to a scientific paper published in March 2013 Y-chromosomal Adam lived between 237,000 and 581,000 years ago.[1]
