The oldest bones in Britain share almost no DNA with anyone alive today. Here’s what that tells us about human history, genetics, and ethnic “homelands."

After more than a million years of separation, two branches of humanity reunited around 300,000 years ago, suggests new research.

Dreams of resurrecting lost species didn’t start in Hollywood or Silicon Valley.
Colorful, blurry streaks of red, blue, and green converge towards the center on a black background, creating a dynamic and radiant starburst effect that illustrates how we see color in all its vibrant glory.
The color of the shirt you're wearing right now depends on many factors, from your eye shape to what language you speak.
A shark swimming in clear blue water showcases the beauty of marine life. It's crucial to save the sharks to protect this delicate ecosystem.
New tests to detect species being traded, as well as population studies, aim to help save them.
For billions of years on Earth, life was limited to simple unicellular, non-differentiated organisms. In a mere flash, that changed forever.

Genes are sometimes called the “blueprint of life,” but that doesn't make them the behavioral playbook.

They have held our fascination ever since we first identified their remains.

While ticker tape synesthesia was first identified in the 1880s, new research looks at this unique phenomenon — and what it means for language comprehension.
Two populations that are geographically separated today once mated a very long time ago.
Disease kills off 40% of farmed catfish. This gene protects them.
What if you could just grow your own blood?
Virtually all the statistical methods researchers commonly use assume potential mating partners decide who they will have children with based on a roll of the dice.
There were many other species of human on the planet. Svante Pääbo discovered one of them.
