Which does nothing to obviate my statement. Homo Erectus didn't just up and disappear once Neanderthals came on the scene, just as it didn't disappear when Archaic Homo Sapiens appeared.
Claiming that since we could not be descended from neanderthals, therefore we must be descended from HE or AHS is like claiming that dogs couldn't be descended from wolves and must therefore be descended directly from fish.
Ted, statements like this prove you've never been able to grasp concept one when it comes to evolution.
If either were LESS primitive, you can bet we'd have heard THAT as a rebuttal, too.
