Map of Old Human Migration


70,000 BC
 new human types (the modern Negro race) repopulate Africa, replacing all but a few of the older Bushmen and West Pygmies


60,000 BC
a small group of the new type migrate out of Africa into southern Arabia. It is believed that this migration consisted of a single band of hunter-gatherers, probably just a few hundred people strong. Many soon move on a southern route to India, Southeast Asia and Australia (becoming Australian aborigines, New Guineans, and part of the mix of South Indians). They must have had raft/ boat building skills to cross the Red Sea and the gulf between Bali and Australia


50,000 BC
 a split in the initial migration takes a slower, second route north into central Asia. They develop lighter skins to allow the limited sun to help with vitamin D absorption. The challenges of an environment harsher than in Africa or southeast Asia may have selected out those with lower IQ's. Their mixed race features can still be seen in areas like Kazakhstan


30,000 BC
ice age warming leads to further migration splits from central Asia into Europe and northeast Asia. They become the Caucasian (Cro-Magnon) and Mongoloid races. Neanderthals die out


25,000 BC
ice age cold provides a bridge from Siberia to Alaska for small groups of migrants, who then populate the Americas


 13,000 BC:
 Eskimos/ Aleuts migrate by boat to Alaska and northern Canada


9000 BC
 Indo-Europeans from central Asia move into central Europe and Southwest Asia, bringing animals and new agriculture. (Basque and Finnish languages are likely holdovers from the original Europeans.)
