@D.S.
Its amusing how it is so difficult for you to admit evolutionists were so wrong about Neandertals.
And its amusing how you keep changing your demands. (Fallacy of moving the goalposts)
You at first claimed that I was "making grossly inaccurate allegations as to what
"evolutionists believed" and saying you "want credible sources from scientific publications"
When that demand was met, you changed it to wanting proof that
scientists had believed or stated incorrectly.
Now that demand was met , and you change yet again asking"Can you name any scientist who himself claims that neanderthals were incapable of speech?" (See quotes and links already provided from GC and myself answering that)
Evolutionists thought Neandertals were incapable of speech because they (Neandertals) "lacked the necessary cognitive capacity and vocal hardware for speech". Science has proven evolutionists were wrong. Why did evolutionists believe in things that were so wrong? Because their belief system tried to deny the humanity of man...and because the Biblical creationists were correct
Associate Professor Stephen Wroe, a zoologist and palaeontologist
"To many, the Neanderthal hyoid discovered was surprising because its shape was very different to that of our closest living relatives, the chimpanzee and the bonobo. However, it was virtually indistinguishable from that of our own species. This led to some people arguing that this Neanderthal could speak,"

Yes... He is correct... It was at that point some evolutionists started thinking maybe their assumptions were wrong. Lieberman then incorrectly positioned the hyoid stating that Neandertals could make inarticulate sounds closer to what a baby or chimp makes. Science has proven Lieberman wrong. Science has proven the evolutionists wrong who tried to deny the humanity of Neandertals.
BTW... Lieberman himself was reluctant to believe Neandertals were capable of speech. When another scientist said the hyoid suggested Neandertals were capable of speech, Lieberman said that conclusion was not supported by the data.
