DNA sequencing technology is helping scientists unravel questions that humans have been asking about animals for centuries. By mapping out animal genomes, we now have a better idea of how the giraffe got its huge neck and ...
Bird skulls and brains look like those of young dinosaurs, providing clues to their unique evolution and modern success.
In a study analyzing the genomes of 210,000 people in the United States and Britain, researchers at Columbia University find that the genetic variants linked to Alzheimer's disease and heavy smoking are less frequent in people ...
Scientists at the University of Chicago studied a massive set of genetic variants of an ancient protein, discovering a myriad of other ways that evolution could have turned out and revealing a central role for chance in evolutionary ...
Evolutionary biologists long have supposed that when species colonize new geographic regions they often develop new traits and adaptations to deal with their fresh surroundings. They branch from their ancestors and multiply ...
Ancient DNA recovered from fossils is a valuable tool to study evolution and anthropology. Yet ancient fossil DNA from earlier geological ages has not been found yet in any part of Africa, where it's destroyed by extreme ...
The advent of farming, especially dairy products, had a small but significant effect on the shape of human skulls, according to a recently published study from anthropologists at UC Davis.
The phrase "survival of the fittest" makes the principle of evolution by natural selection easy to understand—individuals with a trait that adapts them well to their circumstances are more likely to pass that trait along. ...
An international research team working at the Smithsonian Tropical Research Institute in Panama knocked-out a single control gene in the DNA of seven different butterfly species. In the Sept. 18 Proceedings of the National ...
