Neanderthals interbred with non African populations

It hardly mattered if the african HSS picked up sea slug genes on the way to jeruselum so long as they didn't pick up a lot of it.

Must be one sexy slug...

Better to stick it in a sea slug than to have its tip trimmed in order to ratify a covenet with a imaginary sky daddy who would fuck a virgin(?) who would be his own mother so he could also be his own son.

Why is this a big deal? Nothing major in the current conception of human evolution seem to depend on whether Neaderthals and humans ever interbred.

Its a big deal because for years the Out of Africa crowd has insisted that HNS was an evolutionary dead end and that there was no interbreeding between the two.

OOA doesn't depend on HNS being a dead end. It only depends on a small group of what is already HSS, or something so near as to make no different, coming out of africa being responsible for majority of the genetic heritage of all modern HSS outside of Africa. It hardly mattered if the african HSS picked up sea slug genes on the way to jeruselum so long as they didn't pick up a lot of it.

OOA said most of what makes HSS came from Africa, that's it.

If we didn't pick up any genes from outside Africa, that would be sufficient evidence to prove OOA. But that is not necessary evidence to prove OOA.

Well, I didn't devise the theory but recent discoveries will force it to move to your position. However this is the difference between science and religion. Religion would simply dismiss new evidence and burn unbelievers at the stake!

In contrast, the Out of Africa Model13 asserts that modern humans evolved relatively recently in Africa, migrated into Eurasia and replaced all populations which had descended from Homo erectus. Critical to this model are the following tenets:
Out of Africa theory: homo sapiens arose in Africa and migrated to other parts of the world to replace other hominid species, including homo erectus.

after Homo erectus migrated out of Africa the different populations became reproductively isolated, evolving independently, and in some cases like the Neanderthals, into separate species
Homo sapiens arose in one place, probably Africa (geographically this includes the Middle East)
Homo sapiens ultimately migrated out of Africa and replaced all other human populations, without interbreeding
modern human variation is a relatively recent phenomenon

"Without Interbreeding" is a superflous condition.

Unfortunately, the default erroneous assumption through "reproductively isolated, evolving independently, and in some cases like the Neanderthals, into separate species" implies that there is a complete lack of interbreeding.

Which is now proven to be not the case.

Fuzzy sentences can cause bad conclusions.

Lol, I didn't actually read the thing. I don't read things longer than 25 words . I assumed that there was evidence they had sex but.

Hmmn, applying your method makes your sentence interesting.

I've known that since I saw my first game of professional Aussie rules football. The impression was doubly reinforced seeing American gridiron (sorry,can't bring myself to call it 'football')

Participants in both activities seem to be at least 50% Neanderthal.EG one eyebrow,no neck,no jaw,knuckles dragging on the ground,IQ of a cactus and personality of an orangutang in a bad mood.The smell doesn't bear thinking about.

Beetle browed and receeding chined, maybe, but Neanderthals are cleanly, diligent, erect creatures, much more evolved than ball players and much more articulate than creationists.

Oh, am I thinking of Cro-Magnon?

I don't think so. In this poorly-worded instance I think it means that they killed them all without stopping to screw the women. What they are trying to assert is that there is no genetic spill over from HNS to HSS and, of course, they have now been shown to be wrong.

It's a great method. You really only need to take in a minimum of the words to get a grasp of things. As long as

Haha I'm only busting balls.

But seriously... Neanderthals were ugly... why would anyone want to breed with one?

HSS screw sheep (even before they got to Scotland), you think they would pass on a widely spread Neanderthal woman? The "no genetic spill over" is a ill founded, poorly thought out, and totally unnecessary flourish on an otherwise strongly supported theory.

If HSS and HNS last shared a common ancestor less 600,000 years ago, the odds would seem good that mating HSS and HNS can produce biologically viable and fertile offspring is mating were to occur. Different mammal species with lifespan very broadly comparable to humans often seem to retain some measure of this capability even after a couple of million years of evolutionary divergence. However, definition of species is usually more restrictive than that. The two populations must also possess behavioral similarities sufficient to ensure a significant continued exchange of genes in the course of each conducting its normal lives to be considered a single species. So if HSS and HNS lives in contact for several tens of thousands of years, but HNS passed only small amount of genes to HSS, that would in fact suggest HSS and HNS aren't the same species by tighter definition of species.
