摘要: Between 50,000 and 3,000 years before present (BP) 65% of mammal genera weighing over 44 kg went extinct, together with a lower proportion small mammals. Why species extinct in such large numbers is hotly debated. One the arguments proposes that climate changes underlie Late Quaternary extinctions, but global quantitative evidence for this hypothesis still lacking. We test potential role change on extinction mammals during Quaternary. Our results suggest continents highest footprint values, other words, greater magnitudes Quaternary, witnessed more extinctions than exception South America. are consistent across different body masses, reinforcing view past contributed to extinctions. model outputs, dataset, provide new research venue hypotheses about biodiversity dynamics from genetic richness level.
