Some snakes have tough, blunt fangs for cracking crabs. Others have sharp needles for getting a grip on mice.
We studied people's brains while they held tools correctly and incorrectly.
New research combines cutting-edge engineering with animal behaviour to explain the origins of efficient swimming in nature’s underwater acrobats: seals and sea lions.
The utopian 20th-century model of a modern city – one that has been replicated around the world – is being exposed as unsuitable for adapting to the pace of change in the 21st century.
Burials seem to have been uncommon in Africa some 80,000 years ago, although they were widespread in Eurasia.
Given tens of millions of years, wildly improbable events – like primates crossing oceans – are almost a given.
Some animals, such as California sea lions, have small brains relative to their body size, but are still impressively intelligent, showing brain evolution is even more complex than it appears.
Biologists are puzzled by evidence of animals that care for those from other social groups or even species.
The Tasmanian tiger's superficial appearance was so similar to a wolf's that European colonisers assumed it was a threat and hunted it to extinction.
Gigantic flying reptiles had impressive wingspans of up to 12 metres – and a special trick in their necks.
We studied how foxgloves taken to the Americas less than 200 years ago have changed compared to natives in Europe.
We studied the genomes of African and Asian leopards using specimens from natural history museums.
New evidence affirms that significant, long-standing inter-group cultural differences shaped the later stages of human evolution in Africa.
Scientists used to believe that a group containing starfish and sea urchin were the closest relatives of vertebrates like humans. But new research challenges this idea.
A parent's or grandparent's stressful experiences change how their offspring behave. And it turns out that moms' experiences produce different changes in kids than dads'.
Teeth, horns, claws, beaks, shells and even plant prickles — the power cascade rule can be observed far and wide throughout nature, much like the famous golden ratio.
Madagascar stands out as an exceptionally interesting place in which to study the evolution of "mini" creatures. And we are only just starting to scratch the surface of this.
We're the only species that can throw at speeds that kill.
One of the largest groups of 17-year cicadas, Brood X, last emerged from underground in 2004. The next generation will arrive starting in April.
SARS-CoV-2 is much like a zombie virus. It interferes with normal sickness behavior and blocks pain, turning its victims into unsick spreaders of the virus.
