Macroecological analyses support an overkill scenario for late Pleistocene extinctions

Abstract: The extinction of megafauna at the end of Pleistocene has been traditionally explained by environmental changes or overexploitation by human hunting (overkill). Despite difficulties in choosing between these alternative (and not mutually exclusive) scenarios, the plausibility of the overkill hypothesis can be established by ecological models of predator-prey interactions. In this paper, I have developed a macroecological model for the overkill hypothesis, in which prey population dynamic parameters, including … Show more

“…These, at least in principle, constrain excessive hunting and can facilitate sustainable ecosystem relationships ( 63 , 82 , 83 ). Moreover, although overhunting and climate change were likely factors leading to the extinction of several species of large-bodied mammals during the late Pleistocene and early Quaternary in North America, South America, and Madagascar, it is likely that unsustainable predator-prey relationships developed when naïve prey encountered human hunters for the first time ( 84 , 85 ). This contrasts with the situation with many Indigenous Peoples today, who now have long histories in their homelands.…”
