Using data on four species of Darwin's finches on the Galápagos Islands, researchers led by McGill University have confirmed a long-standing hypothesis that species diversity evolves through ...

There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands. All of them evolved from one ancestral species, which colonized the islands ...

An international study led by researchers at Uppsala University (Sweden) in collaboration with researchers at The University of Queensland (Australia) and Princeton University (NJ, USA) used ...

Evolutionary biologists have long suspected that the diversification of a single species into multiple descendent species – that is, an “adaptive radiation” – is the result of each species adapting to ...

Speciation, adaptive radiation, and evolution -- Daphne finches : a question of size -- Heritable variation -- Natural selection and evolution -- Breeding ecology and fitness -- A potential competitor ...

The evolutionary term that applies here is adaptive radiation. That’s when a single ancestor diversifies into a burst of new forms, each filling a niche, exploiting a resource, or responding to a ...

AMHERST, Mass. – They say that hindsight is 20/20, and though the theory of ecological speciation — which holds that new species emerge in response to ecological changes — seems to hold in retrospect, ...

To understand the story of evolution—both its narrative and its mechanism—modern Darwins don't have to guess. They consult ...
