How Long Ago Was the Most Recent Common Ancestor of All Living Humans?

An easy way to think of racial origins is interbreeding, of which there are 3 populations, Neanderthal, Cro-magnon, and Sub-Saharan African. Neanderthal genes are found in Caucasoids and Mongloids, while only Caucasoids have Neanderthal and Cro-Magnon genes, giving Caucasoids their red hair and blue eyes. Sub-Saharan Africans, on the other hand, interbred with an unidentifiable ancestor as recently as 150,000 years ago cut off from a common ancestor 1.5 to 2 million years ago, giving them their ape like features.

Another interesting factoid is that Noah was Caucasian. His sons settled areas from which the 3 branches of Caucasians originate, which means that Adam was Caucasian, and Jesus was Caucasian. Based on this evidence, it's possible that primitive humans already existed on the planet before God made man in his image, which is spirit, and it was the interaction of primitive man with the Adamic line which gave rise to civilization. Therefore, we all, meaning all of mankind is from primitive origins, and it is God Almighty to whom we should be grateful for being made a little lower than himself, that is, being second only to God in the cosmos.
