This dino-bird is super-feathered
This late-Jurassic dino was also a bird. Its ample coat of feathers emerged before any need for flight.
- Archaeology
Neandertal ancestor?
Fossils found in a Spanish cave have features that are a combination of Neandertals and other species. The mix suggests Neandertal roots go back even farther than scientists had suspected.

Old bones ignite fresh debate
Scientists try to understand how 2 million-year-old fossils fit among ancient species.
- Animals
When the giant ants went marching
A new study of an ancient fossil suggests that 50 million years ago, supersized ants went on a cross-continental trek.
