I’m trying to decipher what you found you didn’t like in that one article? The “unchanged for two million years?” That they were “replaced?” That Heidelbergensis was only 1” different?” I’m missing your gist with that... lol
Cro-Magnons or anatomically modern humans, replaced the Neanderthal populations. They were significantly taller than other human species and their average height for both sexes was higher, falling in the very tall individual category.
And it turns out, that's not what happened after all. What a surprise. This kind of wacky cryptoracist BS is found throughout the Replacement model scribbling. Cro-Magnon (and "anatomically modern humans") were "gracile" while everyTHING that came before was "robust" "clumsy" "unable to [fill in the blank]" "doomed to extinction". Even the discussions about Neandertal tend to get steered into the "mystery of why *it* went extinct". The whole thing is creepy, but serves as a nice example of what happens when purported scholars and scientists have to consent to a political model.
The most ridiculous examples are found on each side the topic -- the jackass (died of cancer) in Stanford I think it was who referred to Neandertals as "village idiots" and condemned the morphological approach (as opposed to his nice clean, new-world-order approach of DNA-based research) as being constrained to not ask certain questions (not including the whole, why do we use morphological approach to differentiate different species in the first place, duh); and most of the top dogs in the state-controlled top-down European academic world who claimed that Neandertals and "anatomically modern humans" couldn't have had kids together, even after the DNA showed that, uh, yeah they did. The fact that, on average, much of the Earth's population carries Neandertal DNA in a somewhat greater quantity that it carries the DNA of each of their great-great-great-great-grandcestors shows that most of the genetic basis must have been Neandertal.
