Some, though not all, of the Out of Africa deniers just can't allow themselves to believe that blacks and whites are really the same species. I can't say I know the OP's feelings on this but if I were to judge based on MANY other posts he's made I might suspect he'd prefer if God made blacks and whites as separate creatures -- with whites being superior of course.
But, leaving aside the racial overtones, how do we get from Adam and Eve and there children, presumably of one race, to the many races we have today without evolution? Did God have a separate creation for blacks and another one for whites?
Man has had a hand in evolution and demonstrated, through selective breeding, that a wolf can be transformed into a Black Lab, a Brittany Spaniel, and a Chihuahua, to name just a few. Selective breeding is different than natural selection but it points to mechanisms that effect change.
