I've read there's some genetic evidence that male offspring of a Homo Sapiens and Neanderthal would have been sterile.
So almost a separate species.

That Neandertals and Cromagnons interbred is, IMNVHO, an established fact. Now the question becomes, "How well and how often did they interbreed?" Was the half-breed hybrid offspring successful? As a hybrid a Neandertal/Cromagnon cross might have been mostly sterile, like a horse/donkey cross. Maybe a few of the hybrids were able to breed, but bred with other Cromagnons, diluting the DNA.
E.G., they have spent years trying to crossbreed cattle and buffalo. Looks as if it would be easy, right? So nowadays, we are a modern human/Neandertal hybrid, but the Neandertal DNA is down to just a trace. So, like horse and donkey, we remain two separate species, and with just a trace, we identify with the Mod Hums.
PS:
Warning. All I know about anthropology and Paleontology, I learned from Red Badger and from the pamphlets in a Holiday Inn Express suite.

Given the prevalence of Neanderthal DNA in world populations, the hybrids were anything but sterile.

Also, are there populations around today where the Neandertal Quotient is much higher? Like take me, for instance. I have a long pointy nose and like really thin lips, a big cleft chin, but very prominent brow ridges. How much Neandertal DNA might I have? And, would a DNA test tell me how much?
Many women express an interest in redecorating my cave, but so far I have not had to club any of them.

National Geographic's testing will tell you these things.
I am a PROUD descendant of the Serious Brow Ridge guys with 2.8 % Neanderthal in my makeup. I don't have a serious brow ridge. The average is about 2.1 %. I also have 4.1 % Denisovan ancestry, which is about twice the average amount.

I think the most telling DNA find would be one prior to the Toba eruption 74,000 BC. That is supposedly when homo sapiens sapiens lost 90% of its population base. What was in the 90% lost?
There is also some recent DNA findings which would seem to indicate the the “out of Africa” theory is bankrupt. man may have actually originated elsewhere, possibly South America.

There used to be lions in parts of Europe. They figure in Greek mythology and Greek art, and there is the famous Lion Gate at Mycenae from the Late Bronze Age (about the 13th century BC).
Herodotus reports that lions attacked Xerxes' baggage train in 480 BC, but going after the camels only. He says there were many lions in those areas--between the River Nestos and the River Acheloos (Herodotus 7.12-126). The Nestos is in what is now NE Greece (the coastal strip south of Bulgaria) and the Acheloos is in the western part of central Greece (flowing into the sea opposite the island of Ithaca).

I kinda doubt that humans began in South America. They would have become 'bird food'..........................

People tend to forget that the Cromagnons and Neanderthals shared a lot of DNA that would have been identical, so when we speak of ‘Neanderthal DNA’ we are actually speaking of DNA pieces that are uniquely traceable to them....................

These people come to a conclusion and call it a scientific fact. It is still a conclusion and theory. There are many theories and conclusions. DNA form one bone can not prove much but it causes a jump to a lot of conclusions. Hey, it worked for the 'Global Warming' guys over in the Meteorology Department! We need more funding, too!......................Maybe we could call it 'DNA Change'...............................

The science of Global Warming reached consensus in Neandertal times. In fact, it may even have been a major factor in Neandertal extinction. My Neandertal ancestors, jolly chaps though they undoubtedly were, may have sweated very heavily in their fur garments, and thus possibly were not as attractive to the newcomers in the mating and dating scene as they might have been.
I am moving briskly on and seeking federal grants to clone the Moa and the Dodo and repaint my 240D before the oceans rise.

Depends on which was the breeder, and which was the breedee.

Yet, somehow, other predators like the cave bear and the smilodon were ‘dealt’ with, as were mammoths - all bigger and more dangerous that the birds.
I think the idea humans becoming of ‘bird food’ is a little misplaced. Or a site hit piece. And who do you think extincted them? Nice drum sticks and large portion white meat breasts ... yum.
Back to the DNA - i think, but could be mistaken, that I saw a post on FR that questioned the African origin DNA theory. As I vaguely recall the fossilized DNA in Australian Aborigines does not lead to an African origin.

I know there were dangerous animals everywhere.
Even Siberia has large tigers today!
But Africa had more dangerous creatures than other places.
Lions,
wild dogs,
black mamba’s,
cobra’s,
Hyena’s,
Leopards,
Cheetah’s,
crocodiles,
Rhino’s,
Hippo’s
.....just a partial list.
No wonder Homo Sapiens evolved lot of brain power.
They had to in order to stay alive!

There's also the part that no Neanderthal DNA is in black Africans, so it might be that Neanderthal DNA is part of what makes Europeans and Asians a bit distinct from Africans.

I may have to rent another Holiday Inn Express room and research this.
