Well what hard proof does he have against my statements? Let's remember that even before the DNA tests Neanderthal was thought by paleontologists not to be an ancestor of man for the simple reason that while numerous sites had been found where Neanderthals and humans lived close by, no mixed fossils were found. The reason is simple, they could not produce progeny with each other because they were too different genetically - which is what the DNA research proved beyond a doubt.
Have you read the material? Your questions amount to asking me to read to you from what I have already linked. Didn't you just say you have no problem with science? That's pretty hard to justify if you have a problem with reading.
Once more for the slow learners:
1) Fossils with mixed features exist.2) The only genetic studies so far done use mtDNA, not nuclear DNA. That in turn means:
a. You can have nuclear genes from ancestors who did not contribute to your mtDNA. (Everyone on your father's side unless you're from one of those places where your father's side and your mother's side tend to be the same side.)
b. "Also, mtDNA differences between certain present-day individuals are actually greater than some of those between the Feldhofer Neanderthal and living people (Wolpoff, 1999: 759)."
c. Mungo Man's mtDNA was almost as different from modern humans as Neanderthal mtDNA, but Mungo Man (whether 60K or 35K years old) was anatomically modern.
