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.
In conversation: Martin Rees.
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.
Unlocking the mystery of autism's origin.

The brains of our ancestors grew larger and smarter thanks to an increase in the flow of blood to the brain
Developing lizard embryo beneath placental tissues.
Taking the placenta as a case study, researchers are able to piece together how new organs evolve, by repurposing old tissues and using them to do new jobs.
A new fossil study challenges 130 years of thinking about how dinosaurs evolved.
Dogs are a huge part of their owners’ routines – which makes their loss even more jarring.

Many are embarrassed to publicly show too much grief over the death of a dog. But research has shown just how devastating the loss can be.
There wouldn’t be statues acclaiming Darwin and his theory if it couldn’t stand up to decades of testing.
In science, the word 'theory' has a very specific meaning that's easy for nonscientists to misunderstand or misconstrue. Here's what a theory must withstand to be accepted by the scientific community.
375 million years ago fishes like
Tiktaalik (pictured, above) looked out above water for prey.
John Long, Flinders University
The first truly terrestrial animals evolved from ancient fishes that left the water for land. But what prompted to move has been a mystery.
A baleen whale feeding in the Hauraki Gulf, New Zealand.
Dr Krista Hupman
There are plenty of mammals that have adapted to life in water, some more than others. That meant they also had to adapt the way they feed.
The end was nigh.
Their days were numbered for quite some time ...
Newly recognised genetic populations carry their evolutionary history with them, and the history of their habits. This is why detecting new species is so important.
