A new book explores the complex and gradual process of dog domestication, revealing the extraordinary diversity of dogs that arose during roughly 15,000 years of shared evolution with humans.
A 236-million-year-old fossil has provided evidence that a mammal ancestor was giving birth to live young, potentially rewriting the story of mammalian birth.
Scientists search for 1.7-billion-year-old fossils to understand the emergence of complex life on Earth and its potential elsewhere in the universe.
Researchers have discovered that dozens of animal species possess enzymes capable of breaking down microbial bioplastics called PHAs, a talent once thought to belong only to microorganisms.
Scientists at the La Brea Tar Pits have discovered a new extinct amphibian species, the Ice Age spadefoot toad, which provides surprising new clues about how dramatically Los Angeles' ancient climate changed.
