Late Pleistocene South American megafaunal extinctions associated with rise of Fishtail points and human population

L. Prates and S. I. Perez

This intriguing research by Luciano Prates and S. Ivan Perez explores how human predation contributed to the extinction of South America's megafauna during the Late Pleistocene. Their findings reveal a compelling relationship between advanced hunting technologies and the decline in megafaunal populations.

Abstract
This paper investigates the role of human predation in the Late Pleistocene megafaunal extinctions in South America. By analyzing the temporal and spatial distributions of megafauna and Fishtail projectile points (FPP), the authors find a strong correlation between the rise of FPP technology, human population growth, and the subsequent decline of megafauna. They propose that human predation was the primary driver of megafaunal decline, exacerbated by other environmental factors.
