This small and furry scampering insect-eater lies at the base of the family tree for humans and most mammals, according to the largest-yet study of mammalian evolution.
Bats have already set themselves apart from other mammals as the only members of our class to have mastered flight (sorry flying squirrel, that gliding crap doesn't count). But the secret of flight has given bats some awesome perks.
The rock hyrax doesn't look like much, but it just joined an elite group of animals who display the rudiments of language. The lengthy songs these social mammals sing to each other show evidence of syntax and even regional dialects.
We're used to mice being small and elephants being big, but there's no reason they will stay that way forever. Elephants could become pipsqueaks and mice could get mammoth... and one of those will happen much faster than the other.
The latest State of Observed Species report is out. And biologists might have just earned the title of Hardest-Working People in Science, discovering a staggering 19,232 species in just one year, including nearly 10,000 new types of insects.
Imagine going to sleep for months at a time and then waking up just in time to land on Mars. Hibernation is second nature to bears and other mammals...but there's no reason humans can't do it too.
Scientists have just published compelling evidence that your great (great great...) grandmother was a shrew. Or rather, a shrew-like creature. A team of researchers discovered a new fossil species that they've named Juramaia sinensis, or "the Jurassic mother from China" — a tiny, primitive mammal that dates all the…
Bats are the only mammals that can technically fly, but a lot of other creatures do a pretty good impression of flight by gliding down from the tops of tall trees. But there's a problem: this behavior makes no sense.
The naked mole-rat lives for thirty years - compared to 1-2 years for other rodents - and we've never found any evidence that it can get cancer. Now we're peeking inside its genome to figure out what makes it special.
There's a popular theory that bird and mammal evolution kicked into high gear after the dinosaurs went extinct. But now it turns out lice were already diversifying long before the dinosaurs died out.
