Extinctions in North America were concentrated at the end of the Late Pleistocene, around 13,800–11,400 years Before Present, which were coincident with the onset of the Younger Dryas cooling period, as well as the emergence of the hunter-gatherer Clovis culture.
16 lut 2021 · Since its conception in the 1960’s, Paul Martin’s overkill hypothesis as an explanation for the extinction of most of North America’s Late Quaternary megafauna (animals with an average adult...
2 cze 2020 · Non-metric multidimensional scaling (NMDS) analysis revealed that both the plant and animal assemblages at Hall’s Cave changed significantly across the transition from the Late Pleistocene to...
5 wrz 2018 · In this paper, we summarize the overkill hypothesis and the debate about the cause of the late Pleistocene megafaunal extinctions. We then delve into problems of cross-disciplinary communication by conducting a citation analysis of cited works of Paul Martin, the author of the overkill hypothesis.
21 gru 2018 · Dozens of large mammals such as mammoth and mastodon disappeared in North America at the end of the Pleistocene with climate change and “overkill” by human hunters the most widely-argued causes.
Ancient DNA evidence shows there were population bottlenecks and declining genetic diversity in the Late Pleistocene among a number of extant and extinct taxa, in some instances, beginning well before the first appearance of humans in North America (30–35).
The mechanisms of Late Pleistocene megafauna extinctions remain fiercely contested, with human impact or climate change cited as principal drivers. We compared ancient DNA and radiocarbon data from 31 detailed time series of regional megafaunal extinctions and replacements over the past 56,000 years with standard and new combined records of ...
