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 ...
Parallel adaptive radiations have arisen following the colonization of islands by lizards and lakes by fishes. In these classic examples, parallel adaptive radiation is a response to the ecological ...
Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of ...
When Charles Darwin traveled to the Galapagos Islands almost 200 years ago as a gentleman naturalist, he used the power of observation to develop his theory that species evolve over time. When Charles ...
Antarctic notothenioids represent a remarkable evolutionary radiation of fishes that have flourished in the extreme cold of the Southern Ocean. Their unique adaptations — including specialised ...
The performance of an organism in its environment frequently depends more on its composite phenotype than on individual phenotypic traits. Thus, understanding environmental adaptation requires ...
This work aimed to understand how anemonefish — the colorful reef dwellers best known from Finding Nemo — evolved into such a diverse group of species. Scientists have long assumed that their ...
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 ...
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 ...
