Ancient humans, Neanderthals and Denisovans were genetically closer than polar bears and brown bears, and so, like the bears, were able to easily produce healthy, fertile hybrids according to a study, led by the University of Oxford's School of Archaeology...
The long history of matings between Neanderthals, humans, and Denisovans has only recently been demonstrated through the analysis of ancient genomes. The ability of mammalian species, including ancient humans, to produce fertile hybrid offspring has been hard to predict, and the relative fertility of the hybrids remains an open question. Some geneticists have even said that Neanderthals and humans were at the 'edge of biological compatibility'.
So the team developed a metric using genetic distances to predict the relative fertility of the first generation of hybrids between any two mammalian species. They did this by analysing genetic sequence data from different species that had previously been shown to produce hybrid offspring. By correlating the genetic distance with the relative fertility of the hybrid offspring, it was possible to show that the greater the evolutionary distance between any two species, the less likely it is that the offspring between them would be fertile. In addition, the team used the distance values to determine a threshold of fertility...
When the distance values between humans, Neanderthals and Denisovans were calculated, they were even smaller than the values between several pairs of species which are known readily and easily to hybridise - including polar bears and brown bears, and coyotes and wolves. This suggests we could have predicted the existence of Neanderthals and Denisovans in our genomes as soon as the first genetic sequences were generated.

I keep wondering if today’s white race will be tomorrow’s neanderthal given the recent orgy of self-loathing on our part.
No group with such low regard of itself can possible survive long.
Genesis 6 King James Version (KJV)
6 And it came to pass, when men began to multiply on the face of the earth, and daughters were born unto them,
2 That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
3 And the Lord said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
Her “Weapon of Mass Destruction” question went unused on Powell and Mueller. A virgin question still to be answered.
