Neanderthal's brain matured more slowly than Homo sapiens and other primates

why Caucasus? Neanderthals seem to have developped somewhere in Europe
and at the time it was the northern frontier of continuous human habitation
it was adaptation by selection, their morphology was different from their ancestors

I was talking about mutations, not neandertals

Here's a blog about Neanderthal ancestry by Razib Khan that came out yesterday.

Some interesting facts:

The latest genetic evidence suggests that the first common ancestor of Neanderthals and humans emerged in Africa closer to 750,000 years ago.

...

All non-Africans appeared to be 1–2% Neanderthal in ancestry!

...

Later results have confirmed this. A 40,000 year old modern human from Romania seems to have been 6–9% Neanderthal. Looking closely at the genome the authors suggested that this individual may have had a Neanderthal great-great-grandparent! This means that this individual was even closer to Neanderthals than people alive today, presumably because they were closer to the time of interbreeding.

...

Over six billion humans alive today have some Neanderthal ancestry.

I agree with this fact that under the influence of socio-cultural factors, sometimes something can change. But there is also a common biologic determinant in general. Here an interesting assumption about the female tan an dark skin from the same work:


Probably why Latina types women were popular.

All this can be transferred to the appropriate thread, well, or finish it.

Latina women usually have very curvy bodies, and do not have broad shoulders. The same goes for a lot of southern European women. They tend to have more voluptuous bodies in the right places, than most other ethnic groups. Which is more attractive and feminine, at least imo.

but like the saying goes:

I actually possess the traits for Neanderthal cognition according to the Insitome app for Neanderthal traits:

I guess I can say I was fairly immature up until I was 25 years old. I've been drawing since I was 3 years old, and always had an eye for aesthetics. I've always prided myself on being creative. Even a lot of fashion that's popular nowadays and widely defused, I was wearing back in high school, while everyone thought it was kind of odd. (i.e. Doc martin boots; motorcycle jackets; wayfarer sunglasses) I know that was popular in decades past, but not while I was growing up, especially where I lived.

Early Eurasians had boats 50 ka which is the best explanation. Africans still tend to be afraid of water, and Neanderthals would have made horrible swimmers so they were most likely hydrophobic.

Early Eurasians likely had nets, and a diet rich in fish is known to increase intelligence. Humans could cross large rivers while Neanderthals probably could not. I'm not sure what the caloric advantage of fishing in a boat with nets is, but I bet it is massive if you do the math, and Neanderthals would have had difficulty duplicating the behavior if they were hydrophobic.
 
And yet, in new studies, they excluded the effect of hemoglobin in order to obtain more accurate results on melanin pigmentation. So hemoglobin affects everywhere (including arm), let somewhere in the larger like face, somewhere to a lesser extent.
 
OK. That's it. Jovialis, I know the temptation, and I went off topic too, but please don't respond to him.

Dov, I am removing these posts to a separate thread. If you post one more comment about pigmentation in this thread in direct contravention of two warnings, you'll get an infraction. Am I clear?
 
Then could the loss of brain mass could have resulted in the development of the brain functionality becoming more centralized? Like early computers that took a room, now can be a laptop. The change in brain size, mutations, caused mutations in the DNA?
