Yes I did – thanks for this discussion. I’ve wondered for a while now if anyone had made any connection between Neanderthal/human interbreeding and the Nephilim of Genesis 6? Your description of the latest version of the RTB model sounds strikingly similar to that passage:
This, however, is not the current RTB model. In 2015, they published the second edition of Who Was Adam?, with several updates to the model. To their credit, they acknowledged and accepted the growing evidence for interbreeding between Neanderthals and Sapiens. They adapt their model, in light of this evidence, to acknowledge “bestiality” that arises in our lineage as a consequence of the fall. We might call of this an “Out of Africa and Hybridization” model of origins, where the hybridization is deemed against God’s wishes.
Compare Genesis 6:1-6:
When human beings began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. Then the Lᴏʀᴅ said, “My Spirit will not contend with[a] humans forever, for they are mortal[b]; their days will be a hundred and twenty years.”
The Nephilim were on the earth in those days—and also afterward—when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.
The Lᴏʀᴅ saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time. The Lᴏʀᴅ regretted that he had made human beings on the earth, and his heart was deeply troubled.
