The Lizard's Tale 102: Does Evolution Repeat Itself?

From the creator

Cuba, Hispaniola, Jamaica and Puerto Rico: the four big islands of the Caribbean, are hotbeds of anole activity. But what’s striking is the physical parallels you see between the anoles living on different islands – a phenomenon known as ecomorphism. But did these ecomorphs evolve first and then spread out to the different islands – or did they evolve separately, and then move? A battery of physical and DNA tests help point us toward a conclusive answer – and bring scientists one step closer to understanding the great mysteries of evolution.
