The opposing view, called the ‘Replacement Theory’ tells a very different story – one of incompatibility, revulsion, and perhaps even genocide.
This REALLY needs more context and an annotated citation. There is a question of *why* Homo sapiens survived while Neanderthals did not, but there are sufficient answers to the question without the implication of widespread inter-species violence — environmental factors and natural disasters in addition to interbreeding. Sapiens were more adaptable to their environment but also learning to adapt their environment itself (as Harari has already touched upon in this chapter). What evidence is there of widespread inter-species violence that could have led to Neanderthal’s extinction? Given their physical advantages, purely violent conflicts likely would have favored neanderthals, not sapiens.
