Please explain to me how they know the mitochondrial eve came from Africa? There's no explanation given, other than the fact that it was determined only in 1987 there even was a mitochondrial eve. Back in 1987, the oldest human fossils belonged in Africa so they assumed mitochondrial eve comes from Africa.
Bad logic, because it assumes the fossils were reliable. As we have learned from the footprints found in Britain dating back nearly a million years, our fossil record sucks.
Finally, even if DNA can be traced back to Africa on the mother's side, we still don't know where the fathers are coming from. The fact that they can only trace DNA back 200K years shows how incomplete our picture of humanity's evolution truly is. It is still entirely possible that today's humans are the result of an interesting crossbreed of many types of humans that took place over millions of years.
Furthermore, we don't know how intelligent the predecessors to modern humans were. We don't know their physical characteristics, such as race, either. What if there were an ancient race of humans far more advanced than we are today?
I think what's more interesting is how desperate you and Tenerife are not to be African. Why you find the idea so repugnant is more illustrative of the entire issue of race than any discussion DNA.
For you guys this is a creation/evolution discussion. Not about fact but belief. Chosen belief. You choose to believe that you're not African because being African must be negative in some way.
Suffice it to say, I respectfully disagree.
I'm being a good scientist by questioning previous evidence and demanding rigor. You're being a politically correct race troll by trying to implicate me as some sort of racist because I questioned the current orthodoxy with well-supported reasons.
Check yourself.
I am bringing up a very valid point you should not ignore, and that is very simple:
"How do we know the oldest humans come from Africa?"
It's
a theory. Not a fact.

And the theory was based on large part from the fossil record, to quote:

Genetic studies and fossil evidence show that archaic Homo sapiens evolved to anatomically modern humans solely in Africa, between 200,000 and 60,000 years ago.
Our fossil record sucks! Seriously I'm not trying to be hyperbolic, but our current fossil record is like looking into outer space with a flashlight, and then describing what space is like.
The current fossil record tells us nothing about what life on earth used to be like. It is so empty and devoid of meaningful info that just about everything you hear on human evolution today is speculation.
I am more than willing to bet any man as much money as he wants that in 100 years from now our understanding of human evolution will be radically different. It is a certainty given how bad our fossil record is.
Think about it: most fossils from millions of years ago came from animals who were dumb enough to fall into peat bogs. What if there were intelligent animals during the time of the dinosaurs? What evidence would we have of them? What if they burned or gave proper burials to their ancestors? There would be no fossil record of such a species.
Likewise, what remains of humanity will survive another billion years from now? How many of us are burying humans in peat bogs so they can be preserved for millions of years?
The fossil record is a joke. Until people understand that they will continued to be fooled by evolutionists who think that using the fossil record is anything except a weak crutch.
The people who assumed humanity came out of Africa are wrong, are being proved wrong (as the discovery in Britain shows) as I type, and by the time both of us die humanity's origins will still be a mystery.
