A group of researchers used novel and powerful methods to disentangle the patterns of parallel evolution of freshwater three-spined sticklebacks at different geographic scales across their ...

ANN ARBOR, Mich.---Wings, spines, saber-like teeth---nature and the fossil record abound with examples of structures so useful they've evolved independently in a variety of animals. But scientists ...

Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. Sharks are egg-laying ...

Evolutionary ecologists aim to explain and predict evolutionary change under different selective regimes. Theory suggests that such evolutionary prediction should be more difficult for biomechanical ...

Nov. 23 (UPI) --The ancient teeth of conodonts, one of Earth's earliest vertebrates, have offered paleontologists new proof of parallel evolution. Despite living in distinct geographical regions, ...

A report offers a detailed description of the first nearly complete skeleton of an extinct large dolphin, discovered in what is now South Carolina. The 15-foot-long dolphin (Ankylorhiza tiedemani comb ...
