Humans and other primates are outliers among mammals for having nails instead of claws. But how, when and why we transitioned from claws to nails has been an evolutionary head-scratcher.
Nevada game wardens who spend most of their time hunting down big-game poachers are focusing on a serious threat to nature in a lake: An invasive fish species that eats all the other fish prized by anglers and then turns ...

Prior to the rise of modern day mammalian carnivores (lions and tigers and bears, as well as weasels, raccoons, wolves and other members of the order Carnivora), North America was dominated by a now extinct group of mammalian ...
Evidence from fossils suggests that multiple global warming events, which occurred over 50 million years ago, impacted the evolution of mammals living in ancient Wyoming. Using over seven thousand fossilized teeth, paleontologist ...
The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, ...
Designated wilderness areas provide important habitat for five of Wyoming's migratory big-game species, according to a first-of-its-kind mapping project involving wildlife researchers at the University of Wyoming and cartographers ...
