New Fossils Push Back The Origin Of Mammals By Millions Of Years

A controversial new analysis of the fossilized remains of six squirrel-sized animals has pushed the lineage of modern mammals back to the Late Triassic — a time when the first dinosaurs emerged. The research also suggests that early mammals didn't just hide in the undergrowth. » 9/11/14 11:56am 9/11/14 11:56am

Ancient Egyptian Art Contains The Records of Past Extinctions

Six thousand years ago, the Egyptian wilderness was a very different place. Lions ruled, zebras gathered in large herds, giraffes foraged from tall trees. We know that, in part, thanks to drawings on the walls of ancient Egyptian tombs. Can ancient art help us better understand modern Egyptian wildlife? » 9/09/14 4:22pm 9/09/14 4:22pm

Citizen Science Helped Us Understand More About The Adorable Olinguito

It was just a year ago when the world first formally met the olinguito. The discovery of the creature - the first mammal discovered in the Americas in 35 years - made it the smallest member of the family that includes raccoons, coatis, kinkajous and olingos. Thanks to crowdsourcing, we now know a whole lot more about… » 8/26/14 12:28pm 8/26/14 12:28pm

Researchers Discover New Miniature Mammals in New Guinea

After setting up more than 40 camera traps in a remote mountain range in north-east Papua New Guinea, researchers have captured unprecedented images of previously unknown animals, including this adorable wallaby. » 6/26/14 12:34pm 6/26/14 12:34pm

Most animals can see the flashing and glowing of power lines

In what's turning out to be a rather shocking revelation, researchers have learned that the majority of animals can see pulses of UV light produced by power lines. Because these flashes are often frightening, they may be having a detrimental affect on wildlife around the globe. » 3/13/14 2:20pm 3/13/14 2:20pm

Are any animals truly monogamous?

As Henry Reich explains in this installment of Minute Earth, yes, monogamy does exist in the animal kingdom – though fewer creatures practice it than you probably realize. » 2/19/14 4:00pm 2/19/14 4:00pm

How whales made the dramatic evolutionary shift from land to the sea

All whales and dolphins are descended from terrestrial mammals, ancient creatures that were very similar to the modern hippopotamus. Now, a fascinating new genetics study shows the incredible evolutionary changes these animals had to experience to become the perfectly adapted marine animals we see today. » 11/25/13 7:40am 11/25/13 7:40am

Dogs shaking in slow-motion will make your day WITH SCIENCE

Odds are decent you've seen this video of dogs shaking in super slow-motion (and if you haven't yet, you should – it's a slobbery good time). What you may not know is that there's actually some really fascinating science behind the wet-dog (and, more broadly, the wet-mammal) shake. » 10/23/13 7:40am 10/23/13 7:40am

Shocking discovery: All mammals take about 21 seconds to go pee

That's right, all of them — and the shape or size of the animal doesn't matter. Scientists are calling it the Law of Urination, and it's a process driven by the way mammalian urinary systems evolved to eject fluids from the body in the quickest and most efficient way allowable by physics. » 10/18/13 11:40am 10/18/13 11:40am

This mammal is dying to have sex. Literally.

Some animals, like certain insects, spiders, and plants, die immediately after mating. But what about mammals? A new paper shows that the males of certain mouse-like marsupials face imminent death after having sex — an evolved trait that arose on account of extreme promiscuity. » 10/08/13 8:00am 10/08/13 8:00am

Newly-discovered mammal is 'mix of house cat and a teddy bear'

Say hello to the olinguito, the first carnivorous mammal to be discovered in the Western hemisphere in 35 years. And HOLY CRAP is this thing ever cute. » 8/16/13 2:40pm 8/16/13 2:40pm

This furry Jurassic-era creature was not our ancestor

With its rodent-like appearance, the newly identified Megaconus certainly looks like a mammal. But this forest dweller lived over 165 million years ago, before the rise of the first true mammals. » 8/08/13 12:58pm 8/08/13 12:58pm

How did monogamy evolve?

From an evolutionary standpoint, monogamy doesn't seem to make much sense – especially for males. And yet, it's practiced by a significant number of mammalian species, including humans. Now, in a fantastic example of science in progress, two newly published studies with divergent conclusions seek to explain why. » 7/30/13 12:07pm 7/30/13 12:07pm

How a whale can hold its breath underwater for up to an hour

Unlike humans, many whales can go on hour-long dives without needing to breathe. But no one has been sure how they did it. Now, new research shows it all comes down to a specially adapted oxygen-binding protein in the animals' muscle tissues — a finding that could someday prove valuable in medicine. » 6/14/13 4:30pm 6/14/13 4:30pm

Your afternoon catharsis: wet animals shaking in slow motion – for…

Andrew Dickerson studies how wet animals shake to become dry animals. Last year, in fact, he published the results of a study that examined the wet-shakes of 33 different animals, including some intriguing findings relating shake-frequency and overall animal size. » 3/21/13 12:09pm 3/21/13 12:09pm

This 'grave robbing' mammal outsmarted the dinosaurs by going…

Back during the late Cretaceous period there lived a stocky, mole-like mammal that spent its days burrowing tunnels underground. Called Necrolestes patagonensis, it managed to survive the Age of the Dinosaurs and live for another 45 million years before finally dying out. And as scientists have recently learned,… » 11/20/12 7:40am 11/20/12 7:40am

So this new species of monkey looks exactly like Alan Tudyk

It's not every day that scientists identify a brand new species of mammal. Rarer still is a confirmed discovery of a new species of primate — the mammalian order that encompasses humans, monkeys and apes. Now, for only the second time in 28 years, a new species of monkey has been identified in Africa. » 9/13/12 12:08pm 9/13/12 12:08pm

"Fur particle tracking" reveals the mystery of the wet-dog shake

When a dog gets wet, what does it do? Answer: it shakes, and very efficiently — a large, soggy dog can shed as much as 70% of the water in its fur in just four seconds. » 8/15/12 7:10am 8/15/12 7:10am

Portraits of astronauts from across the animal kingdom

Cats and dogs, rabbits and chimpanzees have all been shot into space, but what about the extraterrestrial dreams of other members of class Mammalia? These strange pop paintings imagine a future filled with gorilla and tiger astronauts. » 4/15/12 7:00am 4/15/12 7:00am
