Reply to Lima-Ribeiro et al.: Human arrival scenarios have little influence on interpretations of late Quaternary extinctions

Abstract

In a recent study (1), we analyzed the pattern of late Quaternary megafaunal extinctions in relation to changes in global climate and the timing of human arrival on different landmasses. Lima-Ribeiro et al. (2) write that some of the human arrival scenarios we considered are more plausible than others and that this affects the interpretation of our analysis. We incorporated a wide range of human arrival scenarios to allow precisely this sort of analysis, and we therefore welcome this contribution. To clarify, we considered 32 human arrival scenarios not to … [↵][1]2To whom correspondence may be addressed. E-mail: davidrwilliams87{at}gmail.com or grahamprescott{at}gmail.com.
