When the environment changes dramatically, animals from mollusks to crows can make big changes in their behavior that enable ...

Trying to understand human behavior (a basic feature of our species, shaped by natural selection) without understanding evolutionary principles would be like trying to understand the details of a car ...

John Maynard Smith is best known for his use of mathematical analyses in biology. Trained as an engineer and then as a biologist, Smith applied game theory to animal behavior and found that although ...

Scientists have long wondered whether evolution would follow the same path if history had a chance for a “do-over.” New research suggests that it does, when it comes to the brain and its regulation of ...

Positive evolutionary psychology uses evolution to help us lead better lives. Three simple tips from this field are as ...

An eye-opening genetic study recently published in Science Advances explores the genetic connection between human bisexual behavior and a previously unknown reproductive advantage. Ph.D. student ...

The study of animal behaviour in ecological and evolutionary contexts examines how behavioural traits develop, persist and interact with environmental challenges. Research in this field investigates ...
