Language bias, not knowledge shortfall, underestimates the evidence of megafauna kill sites in South America

Abstract

The Megafauna Kill Sites (MKS), with irrefutable empirical evidence of human-megafauna interactions over the late Quaternary, have widely been recognized in North America and historically overlooked in South America. Here, we systematically reviewed the MKS from the Americas and showed that the neglected evidence from South American MKS is as robust as or even more robust, in both quantity and quality, than the evidence from North America. However, the South American studies are often limited to low-reach publications (gray literature or local journals) written in Latin languages, which are less cited than English-written publications. Our findings clearly indicate that the neglect of South American MKS is due to its limited scientific impact caused by language bias, and not due to the lack of robust knowledge, inadequate data, or questionable evidence. To reverse this context and put the rich evidence of South American MKS on an international audience, we strongly recommend that South American researchers prioritize publishing their studies in English, the universal language of science since sec. XX. We also suggest making all archaeological evidence readily available in online databases, such as the KillSite database (www.killsitedatabase.com). We believe our recommendations align with the current scope of science, which predominantly operates in English and benefits from the widespread accessibility provided by the internet, and will help South American publications reach international audiences interested in human-megafauna interaction and animal exploitation.
