The secret of the age of human male and female ancestors lies in the Y chromosome and mitochondria  The Y chromosome only passes from the father to the son, while the mitochondria only passes from the mother to the daughter  Through the retrospective study of these two kinds of genetic material, it can be found that all men have a common male ancestor Y chromosome Adam and all women have a common female ancestor Mitochondrial Eve  The researchers sequenced and compared the genomes of 69 men from nine different populations, including Asia, Africa and Latin America, and found that the male common ancestor Y chromosome Adam was formed about 156000 to 120000 years ago
Using the same technical analysis of mitochondria, the researchers calculated that the female common ancestor, Mitochondrial Eve, was formed between 148000 and 99000 years ago
Y chromosome Adam and Mitochondrial Eve were formed at about the same time, their ages are relatively close, Y chromosome Adam may be earlier
