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 ...
It is an evolutionary riddle that has long puzzled scientists ... now the quest to find out why we live beyond 50 is being helped by a new genetic study.
Mass extinctions were followed by periods of low diversity in which certain new species dominated wide regions of the supercontinent Pangaea, reports a new study.
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 ...
A bite from a pit viper, locally known as habu, can cause permanent disability and even death. Yet, much about its venom remains an enigma. Highly variable in composition, even between littermates, this toxic cocktail keeps ...
The next time you bite into that perfect, sweet and succulent watermelon, you may want to appreciate that it's a product of millions of years of evolution in the making.
Once domesticated, dogs spread across the globe wherever humans migrated and settled.
Given how proud we are of our big brains, it's ironic that we haven't yet figured out why we have them. One idea, called the cognitive buffer hypothesis, is that the evolution of large brains is driven by the adaptive benefits ...
A researcher at The University of Alabama was part of a new study that provides further evidence in support of a controversial hypothesis that a group of marine animals commonly called comb jellies were the first to break ...
Three years ago, when Harvard biologist Jonathan Losos settled in at the Geological Lecture Hall for a talk by fellow scientist Richard Lenski, he was toying with the idea of writing a book on evolution. When the lecture ...
