"After Last Year's Hurricanes, Caribbean Lizards Are Better at Holding"


Donihue and his team realized that they had a rare chance to see how natural disasters change the evolutionary fate of a group of animals. After all, they had been the last to observe the anoles before the hurricanes struck. So in October, they flew back to the islands.


“To be honest, given how catastrophic hurricanes are, I thought it was plausible that survival would be random—that there wouldn’t be an advantage that would help [the lizards] survive,” he says. But when he compared the survivors’ measurements with those of the pre-hurricane population, he realized he was wrong.
