Out of Africa. The incredible human journey - Out of Africa 1/5. How the Human Genes we carry came out of Africa and populated the modern world. Since mother's DNA is passed to ALL her children, it can be traced backwards by studying the chromosomal make-up of one's mothers' mother and so on right into the past until all lines converge on one person. Using this technique, Geneticists have actually been able to trace the First Maternal Ancestor of Mankind to Africa and call her the Mitochondrial Eve.
