Long-jawed proboscideans were doing pretty well for themselves. That is, until they were all rapidly replaced with proboscideans with long, flexible trunks instead: mammoths, mastodons, and our modern elephants.What suddenly made long...

Have you ever heard of the Emu War? It was a hilariously disastrous attempt at wild animal population control, and while you'd think that humans would have gotten better at that sort of thing in the last hundred-ish years, that doesn't...

We can't know if or how animals understand death, but behavioral changes in some species could mean they experience something similar to human grief.

Mastodons and woolly mammoths were both ancient relatives of elephants, but they were very different! Join Jessi and Squeaks to see how we can learn all about what an ancient animal ate, just by looking at its teeth.

Come with Jessi and Squeaks as they explore some of the animals that roamed the Earth during the ice age. And a lot of these animals had giant features, like teeth the size of bananas or mouths shaped like a shovel!

Elephants might be strong, but they are weak compared to ants because ants have certain advantages that allow them to outlift their larger competitors.

Woolly mammoths, our favorite ice age proboscidean, disappeared from Europe and North America at the end of the last ice age, about 10,000 years ago. Today, we’ve teamed up with TierZoo to solve one of the mysteries about these...

The mammoths fossils found on the Channel Islands off the coast of southern California are much smaller than their relatives found on the mainland. They were so small that they came to be seen as their own species. How did they get...

How could a body of water as big as the Mediterranean just...disappear? It would take decades and more than 1,000 research studies to even start to figure out the cause -- or causes -- of one of the greatest vanishing acts in Earth’s...

It arose from rhino ancestors that were a lot smaller, but Paraceratherium would take a different evolutionary path. Believe it or not, it actually became so big that it probably got close to what scientists think might be the actual...

People have been discovering the traces and remains of prehistoric creatures for thousands of years. And they’ve also probably been telling stories about fantastic beasts since language became a thing. So, is it possible that the...

There are now more than 7 billion human beings on Earth, and that got me wondering: How successful are we compared to other species? I take a look at out how our numbers stack up to some other domains of life. It turns out that biomass,...

Why do whales, elephants, and other large animals not get cancer? Logically, the larger an animal is, and the longer it lives, the more likely it should be to get cancer. But these giants don’t. Why is that? And can the answer help...

In 2018, an orca called Tahlequah gave birth. But her daughter died within an hour. Tahlequah, however, didn't leave her body. Over the next 17 days and 1,600 kilometers, she kept it afloat atop her own. By altering her feeding and...

How come sharks get to have endlessly regrowing teeth when humans only get one set our entire lives? And how come some other mammals get to cheat the system? From elephants to baboons, we'll learn why teeth don't grow back.

Dinosaurs were huge—it's common knowledge. So why aren't modern mammals anywhere near that size? In this episode of SciShow, Hank gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size...

From changing diapers to cleaning up vomit, human parents can have it tough, but at least they don't have to incubate their babies under their skin or liquify their own guts to feed their brood like these animal moms do! In honor of...

We all know ducks quack, dogs bark, and birds chirp, but that barely scratches the surface of all the amazing ways animals have devised to talk to each other!

Measuring 'intellect' is a difficult task. Check out one way scientists are attempting to make this endeavor more testable. Hosted by: Hank Green

Though he was descended from some of the world's most successful conquerors, Babur struggled to gain a foothold among the many other ambitious princes in Central Asia. So he turned his attention to India, where his descendants stayed and...

In the Serengeti region in Tanzania, conflict can arise between humans and the elephants that graze on their crops. The U.S.-based nonprofit RESOLVE is testing a new way to reduce these clashes while protecting both elephants and humans:...

The Congo Basin is home to the world’s second-largest rainforest and a unique array of biodiversity. But the ecosystem's remote location cannot protect it from the threat of poaching. Special correspondent Monica Villamizar and...
