Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
- Fossils
This bizarre ancient predator snagged soft prey
Scientists are rethinking how this extinct creature used the spiky limbs sticking out of its face to hunt.
- Fossils
T. rex may have hidden its teeth behind lips
Dinosaurs like Tyrannosaurus have long been portrayed with their big teeth bared. But new research suggests this wasn’t so.
- Fossils
Ancient jellyfish? Upside down this one looks like something else
A new look at an ancient sea animal called Essexella suggests it may have been a type of burrowing sea anemone, not a floating jelly.
- Animals
A love of small mammals drives this scientist
Alexis Mychajliw’s science is driven by her love of animals. She now looks to tar pits and fossilized poop to understand ancient ecosystems.
- Humans
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.
- Fossils
An ancient ichthyosaur graveyard may have been a breeding ground
Some 230 million years ago, huge dolphin-like reptiles appear to have gathered to breed in safe waters, just as many whales do today.
- 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.
- Fossils
Let’s learn about pterosaurs
These ancient flying reptiles were not dinosaurs, but they were close relatives.
- Fossils
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.
- Genetics
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.
- Animals
Bizarre ancient critter has spines but no anus
The spiny discovery moves this minion lookalike off a distant limb on the human family tree.
- Animals
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.
