A Short Review on the Origin and Migrations of Modern Humans (Homo sapiens)

Approximately 200,000 years ago, early modern humans (Homo sapiens) appeared somewhere in Africa, and approximately 60,000 years ago, a few members of the early modern humans migrated from Africa to the rest of the world. Finally approximately 10,000 years ago, they were distributed almost all land surfaces of the globe. In the course of expansion, modern humans drove off pre-modern Homo that existed in various regions. However, recent genomic analysis of the nuclear DNA extracted from pre-modern Homo fossils revealed that some pre-modern Homo interbred with some modern humans and left their genes in our genomes.
