It is inconceivable that man, the most curious and mobile of all animals, would not have come to America when the elephants, the tapirs and the deer came from Asia. … Man spread out from Africa to Asia to Europe. It is inconceivable that he would stay out of America."In 1988, the findings of anthropologists Christopher B. Stringer and Peter Andrews, of the British Museum of Natural History further confirmed the single-origin theory, that Homo Sapiens had evolved from an African Homo Erectus group, 200,000 years ago who had later migrated to Asia and Europe about 100,000 later. Both scientists contend that fossil evidence supports their single-origin theory. They also note that the oldest modern looking human fossils, from Western Europe, are only 35,000 years old. Human skull remains, 2.4 million years old were found in Kenya in 1965. This new date places the origin of human beings within the period of major climate change, a global cooling is already believed to have caused other mammals to undergo dramatic evolutionary change. Geologist, John Martyn discovered the fossils while working in the Chemeron Beds in Kenya's Great Rift Valley. The date of the skulls was determined using a new scientific method called Agron.These discoveries help to validate the fact that mankind originated in Africa. Humans born around the Great Lakes region, so very close to the equator, would have been very heavily pigmented. Gloger's Law states that warm-blooded animals born in such an equatorial region as the Great Lakes and Kenya will secrete a dark pigment called eumelanin (melanin).
