The human Y chromosome could disappear over time, putting our species in jeopardy. But some rodents have managed just fine without it – and we now know how.
It’s hard to imagine the world without Homo sapiens. But it’s unlikely we would be here if it wasn’t for a chance asteroid collision.
New genetic research shows humans’ famed ability to adapt our behaviour and develop new tools and techniques has not always been enough to survive when times have grown tough.
The findings come from placoderm fish fossils found in Western Australia’s Kimberley region. This extinct order of fish represents some of our earliest jawed ancestors.
As early modern humans spread across the globe, their gut microbes genetically changed with them. Understanding the origins of gut microbes could improve understanding of their role in human health.
Here’s what we can learn from our closest extinct relatives.
Cutting-edge analysis of fossil ape teeth reveals ancient seasonal change in Africa, long before human ancestors appeared. The method will be crucial for the future study of early hominins.
A language scientist explains that talking was never invented but has evolved over hundreds of thousands of years.
Reproduction is at the very heart of evolution. So why has celibacy persisted for so long?
Around 200,000 years ago, people were living who were as intelligent as us.
Human brains seem to be wired differently to those of chimps or macaques.
New research sheds light on why predators don’t evolve to become so aggressive that they eat all their prey – and then go extinct themselves.
You have a finely honed sense of privacy in the physical world. But the sights and sounds you encounter online don’t help you detect risks and can even lull you into a false sense of security.
Stone artifacts and a fossil tooth point to Homo sapiens living at Grotte Mandrin 54,000 years ago, at a time when Neanderthals were still living in Europe.
To a group of hungry killer whales, a longline fishing boat looks like an all-you-can-eat buffet.
If you ever feel like you can’t stop eating sugar, you are responding precisely as programmed by natural selection. What was once an evolutionary advantage has a different effect today.
Having intelligence helps humans survive.
What looks like a bright, sharp dividing line between humans and other animals is really an artefact of extinction.
Differences between male and female skulls in some species of gibbon may shed light on how our extinct ancestors lived.
Same-sex sexual behaviour presents a paradox: it’s influenced by genes, but how and why do these genes continue to be passed down the generations? One theory is they have reproductive benefits too.
