The genetic ancestor to all men

Posted: Updated:

Every man on Earth has descended from the same man, according to a recent study published in the journal Science.

After studying the uniquely male Y chromosome in men from nine regions, genetic researchers at Stanford University concluded nearly every man on the planet is a direct descendant of one man who lived in Africa some 135,000 years ago.

The study was based on more detailed molecular level analysis of the mutations in Y chromosomes. An exact copy of the Y chromosome is passed on from father to son, so any mutations can point to origins and the time it occurred, so say researchers including those at Mount Sinai Hospital's Genetics and Genomic Science Department.

To be clear, the study is not saying this man was the original human. The first human came about roughly 1 million years ago. This study just says that every man on this planet is connected to the same great great, grandfather if you add 6,750 more greats.

The Stanford study also theorizes from mitochondria DNA that all women on earth are descendant from one woman who lived in Africa roughly 99,000 to 148,000 years ago. These super granddaddy and super grandmommy, say scientists, unlike Adam and Eve, probably did not know each other. But they sure could procreate.
