I'll give you two clues: 1) read some of his posts, and 2) it's not the latter. I don't think that breaks the rules.
But yes, it's another person who simply refuses to believe that the ancestors of the whole human race were black. I leave it as an exercise for the reader as to why certain posters might find such an idea outrageous.
He's clutching at shadows of straws even if he takes his own post as absolute truth.
There's evidence that a small proportion of DNA in modern Europeans comes from interbreeding with Neanderthals.
Assuming for the sake of argument that is what happened, it would be further extremely strong evidence that homo sapiens and homo neanderthalensis had a recent common ancestor. If they weren't very similar on a genetic level, interbreeding wouldn't have been possible. So...where did that common ancestor come from? The evidence (genetic and archaeological) very strongly indicates sub-Saharan Africa.
So at best the OP's post supports a sub-Saharan African origin for humanity that's slightly more complicated than a single migration...which is exactly what the mainstream theory is anyway.
The idea that modern humans, who show remarkably little genetic diversity, somehow evolved seperately as some number of almost identical species in different parts of the world is at best rather far-fetched.
