Madagascar’s unique wildlife faces imminent wave of extinction, say scientists

Study suggests 23m years of evolutionary history could be wiped out if the island's endangered mammals go extinct

From the ring-tailed lemur to the aye-aye, a nocturnal primate, more than 20m years of unique evolutionary history could be wiped from the planet if nothing is done to stop Madagascar's threatened mammals going extinct, according to a new study.

It would already take 3m years to recover the diversity of mammal species driven to extinction since humans settled on the island 2,500 years ago. But much more is at risk in the coming decades: if threatened mammal species on Madagascar go extinct, life forms created by 23m years of evolutionary history will be destroyed.
