Inherent violence of modern humans
During the Pleistocene extinctions, not only animals disappeared, but also other hominin groups. Following the overkill hypothesis, it could be extrapolated to thinking that humans drove other hominin groups to extinction by selectively killing them. This is the specific view of Harari[@harari2015Sapiens: a brief history of humankind] which claims that H. Sapiens drove a genocide on other hominins.
However, this self-fulfilling profecy may not be completely accurate. First, not all hominins drove extinctions in islands, which points to some deficiencies on the overkill hypothesis (although this is so easy to understand and justify that compelling counter-arguments are normally more involved). Moreover, the mixing between modern humans and Neanderthals shows that cohabitation rather than extermination drove the evolutionary forces of human development.
These are the other notes that link to this one.
