What concrete evidence proves that life (for humans) started in Africa?

Wasn't Africa connected to South America and a few other continents thousands of years ago? What evidence out there is contrarion to different "races" of homo sapiens evolving simultaneously in Europe, Asia and Africa? Even Mitochondrial Eve was probably a nomad so she propogated and squirted her ovum all over the paleolithic world.

If the cradle of homo sapien evolution is the African continent, why is the cradle of human civilization the middle east?

Jared Diamond's "Guns, Germs and Steel" answers your second question at length. Main reasons: plenty of animals which could be domesticated, larger variety of seeds which could be cultivated.

+1 because I love anthropology.

Because most Europeans came from the Middle East and then Central Asia - you can watch the movie, "Genetic Odyssey".

I hope this is a serious question, because otherwise I am wasting my time.

  1. Pangaea split about 200 million years ago, Homo sapiens first "walked" the earth about 150,000 years ago.

  2. I am pretty sure you mean species and not "different 'races'". Obviously there are a number of difference races.

  3. There were, in fact, different species of Hominidae walking the earth, in fact there still are (at a minimum) four different species of Hominidae walking the earth.

  4. Depending on where you draw the line in the Neanderthal debate (separate species (as I do) or subspecies) It is true that Neanderthals, Rhodesiensis, potentially Heidelbergensis, and potentially the Red Deer Cave tribe all walked the earth at the same time.

  5. The evidence is primarily anthropological, although some advances in DNA are starting to support the positions.

The cradle of civilization is the Middle East because agriculture was invented there first (and reinvented in many other parts of the world using different foodstuffs, e.g. New Guinea -> sweet potatoes, Mexico -> corn). The original agricultural packet included wheat, barley, millet, lentils, chickpeas, fava beans, grapes, dates, olive, fig, all originating from the Middle East.

Before domesticated animals became available, the package above was superior because it had at least adequate proteins, compared to corn or sweet potatoes for example. People had killed off all the gazelles and there was little else to eat. The archeological record, not surprisingly, shows a collapse in people's height and health when they had to switch to agriculture. Cattle and horses came mostly from the Kazakhstan area, and sheep from the Caucasus, but spread widely. Pigs I believe where domesticated all over the world, and chickens and rice came from China.

To quote Tim from The Quest for the Holy Grail "Look at the bones man! Look at the bones!"

Find some earlier hominid bones in say, South America or Australia, and your silly strawman will be a remarkable new proof for whatever silly racist nonsense you are trying to squirt all over paleohacks with your obvious trolling.

So quit wasting your time and ours, trolling here, grab a shovel, and go digging.

See here : http://news.nationalgeographic.com/news/2002/03/0306_0306_outofafrica_2.html

The multi-regionalism theory, which relies on fossil evidence, holds that after members of Homo erectus first left Africa roughly 1.7 million years ago, they settled in different regions of the world and evolved separately but concurrently into Homo sapiens.
