In the RTB model:
- Humans = Homo sapiens.
- Neanderthals are more close mentally to Apes, and are beasts without intelligence.
- Homo sapiens must arise less than 100 kya, genetically from a single couple
- No interbreeding with Neandertals.
- A lost record of cities and agricultures
It seems they painted themselves into a corner here. @Agauger’s and @vjtorley’s model is much more viable, if they must preserve sole genetic progenitorship. Btw, any more thoughts on the Dabar paper I sent you and the Catholic Genealogical Adam?
