Abstract : The ongoing global decline of biological diversity presents a major challenge for a sustainable future of modern societies. I will bring evidence showing that this decline is accelerating but started already thousands of years ago, as a result of direct anthropic impacts and past climate change. I will showcase how past climate change is driving biodiversity decline, focusing at the genetic level of biodiversity, and has already modified globally current patterns of mammalian genetic diversity resulting from millions of years of evolution. Those evidences strongly suggest the need to incorporate paleo-records and historical dynamics to improve our knowledge on biodiversity erosion and to provide better estimates of species extinction risk, species conservation status and adequate managing decisions in the ground.
