Declining fertility rates may explain Neanderthal extinction, suggests new model

A new hypothesis for Neanderthal extinction supported by population modelling is put forward in a new study by Anna Degioanni from Aix Marseille Universit√©, France and colleagues, published May 29, 2019 in the open-access journal¬†PLOS ONE. The lack of empirical data allowing testing of hypotheses is one of the biggest challenges for researchers studying Neanderthal … Read more Declining fertility rates may explain Neanderthal extinction, suggests new model

Study predicts shift to smaller animals over next century

In the future, small, fast-lived, highly-fertile, insect-eating animals, which can thrive in a wide-variety of habitats, will predominate. These ‘winners’ include rodents, such as dwarf gerbil – and songbirds, such as the white-browed sparrow-weaver. Less adaptable, slow-lived species, requiring specialist environmental conditions, will likely fall victim of extinction. These ‘losers’ include the tawny eagle and … Read more Study predicts shift to smaller animals over next century
