It is understandable why we are eager to find capacities for language and culture in similar species, but the thing that gives homo sapiens the ability to survive is not just language or art, but our ability to organize large numbers of people under trans-familial identities (i.e. advanced political states and culture-defining religion). If they weren't politically (high level behavior control) and religiously (low l…

Civilizations started around 12ka ago. Neanderthals went extinct around 37ka ago.

This is different thing from having the capability to believe so strongly in things like duty and honor that a single king could rule over thousands.

I would call it some sort of language, or substitute "sort" with "type" if the word seems too casual for your tastes. I agree that there may be a lot happening in this world we're unable to perceive, and then your whole argument can be summarized as "anything is possible, we don't really know for sure". Which I now see is why scientists insist on sticking to things that can be measured, proven and quantified. Anythin…

"Which I now see is why scientists insist on sticking to things that can be measured, proven and quantified. Anything else is..." No. Science is a mean to an end, not an end in itself. And intuition, an open mind, imagination help a lot, without drifting into superstition. Read some history, you'll find out that a lot of scientific (and engineering) discoveries were triggered by imagination servicing some more ration…

> So they might even engage in activities we cannot grasp or identify

I don't think that's what they mean when they say imagination: imagining things we can not imagine. And science starts with real imagination, then move on to practical, measurable applications.

Can you provide a citation for your first point? I don't see how Haldane's Rule would support that, but maybe I am missing something.

I am at home tapping away on my iPad so i don't have access to my papers, but it is known there are no Neanderthal genes on the X chromosome. This is what is expected with Haldane's rule where one cross between species is fertile and the other infertile.

I think you've got that backwards. If there were no Neanderthal genes on the x chromosome, then only men would have Neanderthal genes.

I think the fact that we can organize billion souls under the flag of a nation state speaks volumes enough. Did neanderthals have this capacity? I don't know. But if their psychology did not facilitate large scale collaboration, a violent human tribe killing a bunch of them now and again would explain some part why they disappeared. I'm not saying a human tribe hunted them - just that a violent human tribe would atta…

Is there some evidence that neanderthals did not organize themselves in tribes? I think we were just more aggressive and killed them all.

It's not enough to be more aggressive. You have to be more aggressive in larger, more coordinated groups. The greatest warrior in history couldn't fight off an army on his own.
