climate Change Frames Debate Over The Extinction Of Megafauna In Sahul
Climate Change Frames Debate Over The Extinction Of Megafauna In Sahul Explaining pleistocene faunal extinctions remains one of the most challenging problems in the prehistory of sahul (1–3).the vast majority of extinctions across geological time are wholly attributable to climate related factors (), but claims that some, or even all, pleistocene extinctions of large gigantic vertebrates in sahul were the consequence of human activity have generated. The extinction of megafauna has been based on the presumption that the arrival of humans on sahul was synchronous with the disappearance of all now extinct megafauna (36). a link between the two seemed obvious to advocates of a human driven process (37), and a role for climate change was subse quently discounted. the case for a human.

Climate Change Temperature Analysis Shows Un Goals Within Reach Mounting evidence points to the loss of most species before the peopling of sahul and a significant role for climate change in the disappearance of the continent’s megafauna. around 88 large vertebrate taxa disappeared from sahul sometime during the pleistocene, with the majority of losses (54 taxa) clearly taking place within the last 400,000 years. the largest was the 2.8 ton browsing. Mounting evidence points to the loss of most species before the peopling of sahul (circa 50 45 ka) and a significant role for climate change in the disappearance of the continent's megafauna.

Seasonal two way migration is an ecological phenomenon observed in a wide range of large bodied placental mammals, but is conspicuously absent in all modern marsupials. most extant marsupials are typically smaller in body size in comparison to their migratory placental cousins, possibly limiting their potential to undertake long distance seasonal migrations. but what about earlier, now extinct.
