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 ...

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

Weizmann Institute researchers who helped decipher the zebra finch genome have found hints that the birds' sense of smell may have evolved independently. Sequenced zebra finch genome hints that smell ...

An international team of researchers has released a landmark study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for ...

Darwin's finches on the Galápagos Islands are once again providing insights into the theory of evolution, with two studies investigating their dealings with the parasitic avian vampire fly (Philornis ...

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 ...

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 ...

Mountains both help create new species and subspecies of the rosy finch and keep them distinct, according to new research from CU Boulder Speciation—how species come to be—and how species diverge are ...

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, it has been ...
