Summary Introduction
Introduction: Modern human beings that are living on the earth are Homo sapiens. Millions of years ago Homo sapiens evolved in Africa. For the identification of the origin of Homo sapiens, many studies on human mitochondrial DNA (mtDNA) and chromosomal nuclear DNA have supported.
