Few people have the tenacity of ecologists Peter and Rosemary Grant, willing to spend part of each year since 1973 in a tent on a tiny, barren volcanic island in the Galapagos. Even fewer would have ...

The beaks of Darwin's medium ground finches can evolve to crush the shells of hard seeds. Credit: Andrew Hendry They say that hindsight is 20/20, and though the theory of ecological speciation—which ...

A global team of biologists has compiled nearly two decades of field data -- representing the study of more than 3,400 Darwin's finches in the Galapagos Islands -- to identify the relationship between ...

What do the finches of the Galapagos Islands and the lizards of a tiny island at Fairchild Tropical Botanic Garden have in common? They’ve both shaped ideas on evolution. But the lizards of Fairchild ...

How do you know that finches' beak depth is heritable? You can see from Figure 2 that there is a correlation between the parents' and offsprings' beak size. How did the finch population change from ...
