Let’s learn about Neandertals
Neandertals are an extinct species closely related to modern humans. They made tools and jewelry, controlled fires and cared for their sick.
- Archaeology
Neandertals were a lot like our human ancestors
From toolmaking to healthcare, new research finds that Neandertals shared many cultural and social similarities with our human ancestors.

Let’s learn about pterosaurs
These ancient flying reptiles were not dinosaurs, but they were close relatives.

Sprinting reptiles may have been forerunners of soaring pterosaurs
A new analysis of an old fossil supports the idea that winged pterosaurs evolved from swift and tiny two-legged ancestors.

Examining Neandertal and Denisovan DNA wins a 2022 Nobel Prize
Svante Pääbo figured out how to examine the genetic material from these hominid ‘cousins’ of modern humans.

Ancient ‘ManBearPig’ mammal lived fast — and died young
Developing in the womb for a while — but being born ready to take on the world — may have helped post-dinosaur mammals rise to dominance.

This big dino had tiny arms before T. rex made them cool
A predecessor to Tyrannosaurus rex, Meraxes gigas had a giant head. But the muscularity of its puny arms suggests those limbs served some purpose.
- Ecosystems
This giant bacterium lives up to its name
The newly discovered Thiomargarita magnifica is about the size of your eyelash and is surprisingly complex.
- Archaeology
Bright-colored feathers may have topped pterosaurs’ heads
Fossil remains of a flying reptile hint that their vibrant crests may have originated 250 million years ago in a common ancestor with dinosaurs.
