We’ve long known that humans and our cities affect the ecosystem and even drive some evolutionary change. What’s new is that these evolutionary changes are happening more quickly than previously thought, and have potential impacts not in the distant future — but now.

A fossil-free method of sequencing archaic DNA may provide insight into human evolution.

A model of great ape history during the past 15 million years has been fashioned through the study of genetic variation in a large panel of humans, chimpanzees, gorillas and orangutans.

New work in Argentina where scientists had previously thought Earth’s first grasslands emerged 38 million years ago, shows the area at the time covered with tropical forests rich with palms, bamboos and gingers. Grit and volcanic ash in those forests could have caused the evolution of teeth in horse-like animals that scientists mistakenly thought were adaptations in response to emerging grasslands.

Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. UW scientists consider the genetic underpinnings of such evolutionary rescue.

Taking into consideration size, an ancient relative of piranhas weighing about 20 pounds delivered a bite with more force than prehistoric whale-eating sharks or – even – Tyrannosaurus rex.

Moths are able to enjoy a pollinator’s buffet of flowers because of two distinct “channels” in their brains, scientists have discovered.
