The ancestors of modern humans interbred with Neanderthals and another extinct line of humans known as the Denisovans at least four times in the course of prehistory, according to an analysis of global genomes published on Thursday in the journal Science.
The interbreeding may have given modern humans genes that bolstered immunity to pathogens, the authors concluded.
“This is yet another genetic nail in the coffin of our over-simplistic models of human evolution,” said Carles Lalueza-Fox, a research scientist at the Institute of Evolutionary Biology in Barcelona who was not involved in the study.
The new study expands on a series of findings in recent years showing that the ancestors of modern humans once shared the planet with a surprising number of near relatives — lineages like the Neanderthals and Denisovans that became extinct tens of thousands of years ago.
Once depicted as brutal, grunting, slouching sub-humans, Neanderthals are now known to have had brains as large as ours and their own distinct culture. They buried their dead, tended their sick and co-existed with our own ancestors in Europe for thousands of years before becoming extinct just as modern humans flourished and began to spread throughout the continent. This list looks at ten of the most persistent myths about Homo neanderthalensis.

The first wave out of Africa and into Western Eurasia? If I'm interpreting you correctly, I would agree that this is a likely answer.
Have you seen this commentary on a recent paper, from Dienekes Blog?
The picture on the left[actually below] (source) shows quite nicely that according to current understanding, Africans are nested within Eurasian genetic variation. The modern humans have the following structure:
(Early modern human lineage detected as admixture in the Altai Neandertal, ((Asians, Europeans), Africans)),
and then there are two deeper layers of Eurasian hominins (Neandertal/Denisovans) and the "Mystery hominin" that mixed into Denisovans.
Africans are thus just a leaf of the Eurasian family tree, casting serious doubt -if this model is to be believed- to the position that H. sapiens originated in Africa and are descended from people who never left the continent. It seems much simpler to derive them from an early migration (~200kya?) from Asia which would nicely explain why the continent's first sapiens populations appear tentatively in the northeastern corner, and why they do not replace archaic hominins for most of the 200 thousand years until today. In a reversal of perspective it is not Skhul/Qafzeh that are the "migration that failed", but rather the Omo 1 outlier is.
Are living Africans nested within Eurasian genetic variation (?)
It's an interesting view point.
As to the language thing, there are some fascinating aspect about languages that can give us some insight into how ealry people got around.
I get into it a little later, its the first nice day in a week and the dog really wants a walk.

=> therefore "hominins" are indeed members of the human species.
Contemporary people born and living in the wilderness differ little in appearance from "hominins" and aren't a step closer to other species either.
If they're not too radioactive may be they've been alive millions of years ago.
That does not mean all members of the genus are the same species however.
I find it amazing that so many people don't blink at the vast array of fauna that are different species of the same genus but as soon as you bring the Genus Homo into the mix all holy hell breaks loose and science is a sham forced down our throats by magical men in a high ivory tower.
The only thing radioactive is your aversion to learning about actual science because it conflicts with your young earth worldview.
Neanderthals, or even older Homo erectus("Upright Man") might have sailed around the Mediterranean, stopping at islands such as Crete and Cyprus, new evidence suggests. The evidence suggests that these hominid species had considerable seafaring and cognitive skills.
"They had to have had boats of some sort; unlikely they swam," said Alan Simmons, lead author of a study about the find in this week's Science. "Many of the islands had no land-bridges, thus they must have had the cognitive ability to both build boats and know how to navigate them."
