The finches that call Ecuador’s Galápagos Islands home are biological rock stars, as they provided a key piece of evidence for Charles Darwin’s theory of evolution. One reason for this is how new ...

The 14 species of Galapagos finches that have inspired evolutionists since the days of Charles Darwin may reveal yet more. The birds may have evolved different courtship songs as byproducts of beak ...

Peter and Rosemary Grant would fare well on "Survivor." Living alone on a small, uninhabited island, communicating with the mainland only by radio and relying on a national park service's monthly ...
