….One step forward and two backwards for proving Evolution of man from primates ?
Though evidence for or against human-Neanderthal fraternisation may draw all the popular attention, evolutionary biologists are eager to apply the data to less prurient projects. First among those will be understanding what makes humans human.

That is totally irrelevant to the subject matter of the web link.
The web link is CLEARLY nothing to do with “proving Evolution of man from primates” but was rather is about the Neanderthal genome and the lack of evidence for human-Neanderthal fraternisation.
….My question has been, how do you know that these Neanderthals were not degenerated humans rather than evolving primates ?
What premise is there to believe they were “degenerated humans”?
This would be a rather absurd hypotheses because it would beg the questions of what made them become “degenerated” and, if they where indeed “degenerated”, why didn’t natural selection almost immediately eliminate them in favour of modern humans? After all, the evidence suggests that Neanderthals and humans lived side by side for many thousands of years.
Also, it is quite absurd to suggest that Neanderthals were simply “degenerated” because they may have actually had larger brains than us!
“….Neanderthal cranial capacity is thought to have been as large or larger than modern humans, indicating that their brain size may have been the same or greater….”
Also, in the
link, it clearly says:
“…The new sequences suggest that the Vindija Neanderthal lacked the ability to digest milk sugar in adulthood – a trait that became common among northern Europeans and Africans only in the last 10,000 years.
Two gene mutations cast further doubt on widespread sexual relations with humans. The Vindija Neanderthal lacks a version of a brain development gene, microcephalin-1, that some researchers had hypothesised humans picked up from Neanderthals. The same goes for a mutation in a gene linked to brain ageing and Alzheimer's called Tau
This clearly indicates that there are significant genetic differences between Neanderthals and modern humans thus this is good evidence that they are NOT a type of modern human let alone a “degenerated form“ of human.
isn’t the idea of “degenerated forms“ of human ( or so called “sub-humans" ) one that was propagated by the nazis?
link is interesting because it shows the best evidence yet that humans and Neanderthal probably didn’t ever successfully cross-bread although, of course, this possibility is by no means ruled out.
