It's good to be precise though, isn't it Chuck? We came out of Africa....but, like people do on the march, we took the time to fuck a few locals here and there.
I am the Infantry. I am my country’s strength in war, her deterrent in peace. I am the heart of the fight… wherever, whenever. I carry America’s faith and honor against her enemies. I am the Queen of Battle. I am what my country expects me to be, the best trained Soldier in the world. In the race for victory, I am swift, determined, and courageous, armed with a fierce will to win. Never will I fail my country’s trust. Always I fight on…through the foe, to the objective, to triumph overall. If necessary, I will fight to my death. By my steadfast courage, I have won more than 200 years of freedom. I yield not to weakness, to hunger, to cowardice, to fatigue, to superior odds, For I am mentally tough, physically strong, and morally straight. I forsake not, my country, my mission, my comrades, my sacred duty. I am relentless. I am always there, now and forever. I AM THE INFANTRY! FOLLOW ME!

Indeed, few would be the locals we HSS did not see to fit to debauch on our path to global hegemony.

But it was their theory, Chuck. And the reason they insisted on it was that they wanted HNS and HSS to be separate species incapable of interbreeding.
At this point it is back to the drawing board.

The notion that different species must be totally incapable of showing evidence of interbreeding is widely held and circulated, but false.
1. When two populations are sufficiently different such that when they fuck each other, their pool of offsprings would consistently exhibit demographic or phenotypical traits highly atypical of either parent population, these two population would, if alive today, be considered different species. So for example, if HSS and HNS are sufficiently similar to fuck, and to give rise to children, but only female children ever result from such union, then HSS and HNS would be considered different species. Or if HSS and HNS fuck, and all children are dwarves or giants, and have reduce fertility, compare to either parent population, then HSS and HNS would be considered different species.
2. When HSS and HNS can not directly interbreed, but do represent opposite ends of a still existent genetic continum, such that they can pass genes from one to the other through an intermediate population with whom they can both freely interbreed, then they would be different species but would be able to show signs that makes it appear as if they interbred.

But that's not what they originally claimed.
You are employing revisionist history.

There is no revision. The fact that "if not A therefore not B" is valid does not logical require "if A, therefore B" to also be valid.
If HSS and HNS coexisted and yet never interbred, that would be strong evidence they were not of the same species. But if they did appear to interbred in some limited way, that does not prove they were therefore of the same species.

They are symbiotic, festering in each other's oozing embrace.

But it does invalidate their original claim that they did not interbreed at all.
They can ( and should ) revise their theory. This happens all the time in science. It is what makes science superior to religion.
