Only DNA fingerprinting could shed light on this.Fossils might also be of help.

As far as I know, there is not such a theory, nor basis for supporting it....there is no evidence that human race emerged or appeared in two different parts of the planet....If that were the case, the evidence goes in OPPOSITE direction,..,,,,one piece of proof,,,we all humans share the same genoma....the variations are product of individual changes that give us the phenotype....
If we came from different parts of the planet, there would be different kinds of DNA and phenotypes (of course, also different phenotypes),,,,despite that, any human (fertile) can procreate and thrive, by mating any given individual of the opposite sex, from anywhere else on earth...that sound pretty logical does it not?

I have heard it argues that humans could not have spread across the globe as rapidly as they did, unless they evolved in places other than just in Africa. I do not know if that is the current arguement.
