I also have tremendous respect for Dr. Hugh Ross, Dr. Rana, and RTB. As recent as January of this year (2018), at the ASA Southern California Day Conference, I asked Dr. Ross about his views on the descendants of Adam and Eve. And at that time, at least, he seemed to be of the view that there was no interbreeding with Neanderthals and that RTB had doubts about the reliability of the Neanderthal genetic evidence. I believe he suggested that perhaps Europeans had contaminated the Neanderthal genetic studies and perhaps researchers from Africa (presumably because they have been shown to not have interbred with Neanderthals) should investigate Neanderthal specimens as to be sure not to contaminate the genetic record. I could have misunderstood his comments and I don’t want to misrepresent what their model may show, but this is just my understanding of what I thought I heard in response to my question.
