The pluses and minuses of microdroplet separation

Adaptive radiations—species descended from a common ancestor that are adapted to a wide variety of ecological niches—occur frequently on remote islands where a colonist finds few competitors in an unexploited ecological landscape. We examined ...We investigated whether celebrated cases of evolutionary radiations of passerine birds on islands have produced exceptional morphological diversity relative to comparable-aged radiations globally. Based on eight external measurements, we calculated the ...
