Genetics or evolution first? No brainer.
Researchers find striking results from a large study of secondary school students.
Some sea animals with smooth shells can dig themselves into the sand in just a few seconds.
Maëlle, 7, wants to know why some shells are smooth, while others are corrugated. It turns out that while corrugated shells are strong, smooth shells can move fast.

Africa has one of the world's richest fossil records, and evidence suggests that amateurs collected really important fossils long before professionals arrived on the scene.
Does God exist?
There remain many mysteries that are beyond science. Does that mean that a God truly exists? A scholar gives reasons for this possibility.
Artificial intelligence can bring many benefits to human gamers.

Twenty years after Deep Blue beat Garry Kasparov at chess, artificial intelligence can make games more fun, and perhaps even endlessly enjoyable, if it learns to adapt.
The stone flakes are flying, but what brain regions are firing?

We can't observe the brain activity of extinct human species. But we can observe modern brains doing the things that our distant ancestors did, looking for clues about how ancient brains worked.
Did Puss in Boots have it all wrong?
Cats evolved in hot desert regions where there were lots of small animals to eat. So they evolved feet that are perfect for pouncing on prey, climbing, scratching and jumping from great heights.
Elephants express many extra genes derived from the critical tumour suppressor gene TP53.
Elephants naturally avoid cancer after 55 million years of evolution. Scientists are studying if they can extract lessons that could help people.
A Pirahã family.
From the Amazon to Nicaragua, there are humans who never learn numbers. What can these anumeric cultures teach us about ourselves?
Darwin was right again.
Epigenetics is consistent with the theory of evolution – in fact, Darwin predicted that tiny parcels might somehow provide a flow of information from experience to inheritance.

Researchers pieced together evidence from fossils that had been sitting in museums for years.
What do we really know about the link between a species' sex life and how it evolves?
Our cells have a built-in genetic clock, tracking time… but how accurately?

How do scientists figure out when evolutionary events – like species splitting away from a common ancestor – happened? It turns out our DNA is a kind of molecular clock, keeping time via genetic changes.
The latest research dismisses the idea that viruses form a fourth type of life.
A new study shows cephalopods edit messages from their DNA, allowing them to adapt faster to their environment.

The Astronomer Royal answers some of the world's – and the universe's – biggest questions.
Choerophryne frog from the Foja Mountains in New Guinea. This one is a calling male.
Tiny frogs that have spread across New Guinea's isolated mountains could face an uncertain future if a warming climate pushes them higher up the peaks.
Flora and fauna can adapt to climate change, but some are more successful than others.
Australia's animals and plants are already demonstrating their resilience to climate change.
