"Y-Chromosomal Adam" and "Mitochondrial Eve" are the names given to two ancient human beings who science has proved are genetic ancestors of every living person. Every man alive today is descended from "Y-Chromosomal Adam," while every man and woman alive today is descended from "Mitochondrial Eve." The Y-chromosome is one of a pair of sex.
