The extinction risk to Madagascar's mammals, including unique species like the lemur, threatens a biodiversity crisis that would take more than 20 million years to heal, scientists warned Tuesday.
The southern Indian Ocean island has been cut off from the African continent for over 80 million years – a separation that has developed an extraordinary array of plants and animals, many of which cannot be found anywhere else on Earth.
If the losses were stopped now, it would take 3 million years for nature to recover with the emergence of similar complex mammal species to replace the ones already lost, they found. "This will have dramatic implications for human livelihoods in the region, leading to starvation and mass emigration."Madagascar is a biodiversity hotspot, meaning it has a large population of species that cannot be found anywhere else.

It would take 23 million years for evolution to replace Madagascar's endangered mammalsIn many ways, Madagascar is a biologist's dream, a real-life experiment in how isolation on an island can spark evolution. About 90% of the plants and animals there are found nowhere else on Earth. But these plants and animals are in major trouble, thanks to habitat loss, over-hunting, and climate change. Of the 219 known mammal species on the island, including 109 species of lemurs, more than 120 are endangered. A new study in Nature Communications examined how long it took Madagascar's unique modern mammal species to emerge and estimated how long it would take for a similarly complex set of new mammal species to evolve in their place if the endangered ones went extinct: 23 million years, far longer than scientists have found for any other island.
