Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn ...
DNA molecules in lake sediment are few and hard bound to particles. This resulted in challenging analyses and required development of new methods, both for extracting sufficiently clean DNA and for the statistical analysis ...

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 ...
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 ...
