Animal science

A groundbreaking study has traced the 66-million-year history of primates to overturn conventional thought that our ancestors came from tropical forests. The earliest members of our family tree, scientists say, were actually cold-climate survivors.

Leopard seals may be one of Antarctica’s most fearsome predators, but these vocalizers sing with the structured charm of a nursery rhyme. In a new study, researchers discovered that the underwater vocal patterns of these mammals resemble human song.

They’ve been crawling across the seafloor for 500 million years, but some sea stars have amassed such a population they're eating entire reefs alive. Now, a discovery about their spine-speaking chatline gives us a leg up in this ecological arm's race.

The first known cases of accidental choking have been discovered, dating back 150 million years, when some ambitious fish got more than they bargained for while picking off algae from squid-like carcasses. It's history's oldest mealtime misadventure.

Researchers have identified a fascinating behavior in killer whales: they sometimes offer to share their prey with humans. And while the orcas haven't gone on the record to confirm it, it's likely their way of building relationships with us.

If you, like us, were under the impression that two-legged dinosaurs were pacy beasts that could zip across the ground at around 40 mph, researchers have some bad news. A new study suggests they were much, much slower than previously thought.

Killer whales have joined the rare club of animal species that craft tools out of nature and use them to their advantage. For the first time, they've been observed making a brush of sorts out of kelp and then using it on each other.

More than a third of large animals that feast on dead animals are struggling to survive, and a new report from scientists warns that their downfall could present a serious risk to human life, with an uptick in zoonotic disease spread as a result.

It turns out that donkeys are exceptionally good at repelling deer ticks. Now, researchers at the University of Massachusetts Amherst have harnessed that ability to create a natural bug repellent that proved as effective as DEET at fighting the pests.

It's not a simple case of "follow the leader" when it comes to baboons on foot. Researchers have made a surprising discovery on why they appear to move in an orderly line, and it's something that can help us better understand human behavior, too.

Wearing face masks and maintaining social distances were a significant part of the world's reaction to the COVID-19 pandemic. Now, new research says the practices are not only effective at saving human lives, but chimp lives as well.

In an impressive feat of urban adaptation, sulphur-crested cockatoos have worked out how to use their feet and their large bodies to twist the taps of drinking fountains. And much like another of their moves, they're learning to do this en masse.
