evolution

Thomas Smith of the Institute of the Environment and Sustainability says the next great extinction could be upon us, but humans can help threatened species survive.

UCLA professor Tom Smith says human-driven evolution is creating drug-resistant diseases, pesticide-proof bugs and mass extinctions due to climate change. "We can either choose to manage evolutionary processes or not, but evolutionary change will proceed regardless."

Drug-resistant diseases, pesticide-resistant bugs and animals threatened by climate change are signs of human-driven evolution getting out of control. A multi-university team calls for solutions.

Phony laughter, unlike the real thing, is unique to humans, says Greg Bryant, who is studying the acoustic properties that differentiate the two types of cachinnation.

Caribbean fighting conch used to be harvested with more meat, but evolved to mature at a smaller size.

A study by researchers at UCLA and the University of Texas reveals gender differences in sexual regret and traces them back to our evolutionary past.

For Old World primates, the variety and complexity of their facial colors and patterns play a major role in helping them identify members of their own species and communicate with one another.

Wolves were probably domesticated by European hunter–gatherers and gradually evolved into dogs that became household pets, a new study suggests.
