While volcanism caused a temporary cold period, the effects had already worn off thousands of years before the meteorite, the ultimate cause of the dinosaur extinction event, impacted.

Scientists have discovered the oldest known animal with saber teeth: a predator that lived 270 million years ago. This animal, from before the age of the dinosaurs, was a dog-like creature that was related to the ancestors of mammals.

The fossilised remains of an ancient carnivore provide intriguing hints about how early relatives of mammals began regulating their own body temperature

The Greater Mekong region of Asia hosts a wealth of rare and unstudied species – 173 new species of plants, 26 reptiles, 17 amphibians, 15 fish and three mammals were described last year. Here are six of them

Glaciologists used sound waves to reveal Ice Age landforms buried beneath almost 1 km of mud in the North Sea. The results suggest that the landforms were produced about 1 million years ago, when an ice sheet centered over Norway extended towards the British Isles.

Nearly all living organisms use the same genetic code, a complicated mechanism by which genetic information is translated into proteins, the building blocks of life. A new study suggests conventional wisdom about how the code evolved is likely flawed.

Neanderthal genes make up 1-2% of the genomes of non-Africans. Scientists analyzed the lengths of regions of Neanderthal DNA in 58 ancient Eurasian genomes of early modern humans and determined that the introgressed genes result from interbreeding between Homo sapiens and Neanderthals about 47,000 years ago, over a single, extended period of about 7,000 years. The findings help pin down dates for out-of-Africa migration and the dispersal of Homo sapiens.

Few genomes have been sequenced from early modern humans, who first arrived in Europe when the region was already inhabited by Neanderthals. An international team has now sequenced the oldest modern human genomes to date. The genomes were recovered from seven individuals who lived between 42,000 and 49,000 years ago in Ranis, Germany and Zlaty kun, Czechia. These genomes belonged to individuals who were part of a small, closely related human group that first split off from the population that left Africa around 50,000 years ago and later settled the rest of the world. Although they separated early, the Neanderthal DNA in their genomes traces back to an admixture event common to all people outside Africa, that the researchers date to around 45,000-49,000 years ago, much later than previously thought.

A fungus named Psilocybe ochraceocentrata is the closest relative of a widely cultivated psychedelic mushroom, giving clues to their evolutionary origins

A new study sheds light on the lives of people who lived over 5,600 years ago near Kosenivka, Ukraine. Researchers present the first detailed bioarchaeological analyses of human diets from this area and provide estimations on the causes of death of the individuals found at this site.

A new study estimates that more than 9000 insects and other native invertebrates have become extinct in Australia since European arrival in 1788 and between 1-3 additional species become extinct every week.

They were loved by Charles Darwin, they build brilliantly bad nests and they even produce a kind of “milk”. Surely, these facts are more than enough to foster a love for the urban pigeon

Rats of the sky? Pigeons are often the target of human ire, but there's a lot to cherish – or at least appreciate – in these scrappy survivors

Dog harnesses are sometimes claimed to reduce pulling forces on the leash, but an experiment found they have the opposite effect

Geoscientists have created a new climate record for early Antarctic ice ages. It reveals that the early Antarctic ice sheet melted more rapidly than previously thought.
