Evolution: What is it? How does it work?

Nature has a way of pressuring creatures to adapt to their environments over generations.

Babies born on Mars could diverge from Earthlings within a couple of generations

Mars is a strange place and any humans born there are bound to look radically different.

Humans and Neanderthals diverged at least 800,000 years ago, new teeth study shows

This just goes to show how complex our evolutionary history really is.

Ancient amphibious whale with four legs and hooves dared to cross the Atlantic

This creature had a whale of a time.

The genders kill differently — and one paper proposes it’s because of our ancient roles

I do like this theory.

Fossil Friday: Newly-found fossil teeth solve ancient monkey mystery

Take a bite out of this story.

Megalodon’s teeth evolved over 12 millions years, researchers find

This is not the Nemo you’re looking for.

New research suggests humanity’s ancestors began walking upright earlier than believed

Walk like an Egyptian?

Seen more spiders lately? That’s because they’re no longer afraid of the light, researchers say

So that’s why…

Poaching evolution: elephants are evolving to lose their tusks

It would be an amazing example of evolution — if it weren’t so tragic.

Barn swallows have evolved to live alongside us, new research reveals

They live with us, but they’re not domesticated.

Humans are exterminating mammals faster than evolution can keep up

Saving biodiversity makes more sense than waiting millions of years for it to re-evolve.

Stunningly preserved 228-million-year-old fossils shed light on mysterious turtle origins

The turtle relative is the oldest with a beak.

The Timeline of Human Evolution

We’re taking you for a ride through evolutionary memory lane, carefully listing the members of our long family tree.

The world’s first animals also caused the first global warming event — but it took 100 million years

There’s a metaphor here, and an important lesson for ourselves.

One genetic change 3 million years ago made our brains big — and won us the world

I’m not complaining.

Earth’s first giant predators produced killer babies

If the adults weren’t scary enough, the babies were also killing machines.

Early baleen whales were fearsome predators with wicked teeth, but lost them entirely

Baleen, one surprising fossil suggests, evolved from gums rather than teeth.

Mass extinctions don’t come out of the blue — and we’re seeing some of the signs today

An incoming mass extinction isn’t as hard to spot as we’d believed.

Darwin’s “advertising” — the magnificent biological art of Ernst Haeckel

You might have not heard his name, but you should have.
