I want to know the answer to the following question:
What has Jared Diamond blamed the decline of gatherers on?
All the background I'm provided with is that "In North and South America, for example, most large mammal species had gone extinct by the end of the Pleistocene—according to Diamond, because of overexploitation by humans, although the overkill hypothesis he advocates is strongly contested.[by whom?]". Is that enough to answer the question?
Answer: no
