Biological Evolution: Unity and Diversity
- Animals
Scientists discover the first true millipede
The newfound deep-living species tunnels belowground using a whopping 1,306 legs!
- Animals
As the tropics warm, some birds are shrinking
Migratory birds are getting smaller as temperatures climb, studies had showed. New evidence shows dozens of tropical, nonmigratory species are, too.
- Animals
Let’s learn about chimpanzees and bonobos
Humankind’s closest cousins in the animal kingdom may look similar, but in terms of behavior, they’re polar opposites.
- Life
Scientists Say: Adaptation
This word refers to a feature of a living thing that helps it better survive in its environment — or the process of that feature evolving in a population.
- Fossils
‘Penis worms’ could have been the original hermits
These soft-bodied critters lived in abandoned shells about 500 million years ago, a new study suggests.

Explainer: The age of dinosaurs
Take a trip back to the Mesozoic Era to explore how geologic events, ecosystems and evolution were connected during the so-called age of dinosaurs.
- Fossils
Fossils point to earliest dinosaurs that lived in herds
A fossilized family gathering of long-necked Mussaurus from 193 million years ago is the earliest evidence yet of herd behavior in dinos.
- Humans
Genetics show humans likely trace back to Africa
Our history began looking ever more complex once geneticists revealed our ancestors picked up new DNA as they traveled across time and continents.
- Humans
The ultimate genealogical search hunts for our earliest ancestors
The complex search to identify humans’ most distant cousins is long, complex and far from straightforward. It’s also far from over.
- Animals
What biologists call a species is becoming more than just a name
The tree of life — evolution — has been reshaping how scientists name and classify organisms. Some want naming to reflect evolutionary groups even more.
- Animals
Will the woolly mammoth return?
Scientists are using genetic engineering and cloning to try to bring back extinct species or save endangered ones. Here’s how and why.

Cloning boosts endangered black-footed ferrets
A cloned ferret named Elizabeth Ann brings genetic diversity to a species that nearly went extinct in the 1980s.
