In 1964, renowned biologists Peter Raven and Paul Erhlich published a landmark study that introduced the concept of co-evolution. Using butterflies and plants as primary examples, the team determined that two species can ...
New research led by the University of Nebraska-Lincoln and the University of New Mexico has pinpointed changes in a single, mutation-prone gene site that ultimately allow wrens to breathe easy in the rarefied air of the Andes.
Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions ...
Sexual conflict between males and females can lead to changes in the shape of their genitals, according to research on burying beetles by scientists at the University of Exeter.
