Humans eat a lot of different animals, but almost none of them are carnivores - why?

In this SciShow Kids compilation, Jessi and Squeaks revisit some of their favorite winter activities and learn a little science along the way.

When it comes to piecing together what happened to civilizations that no longer exist, it can be challenging to solve the mystery. But research into Angkor, the Akkadian Empire, and even the Norse of Greenland, is helping us see that...

Lizards are incredibly widespread and diverse but it took them a long time to get to where they are now. Because they used to face some pretty stiff competition from a group of lizard look-alikes.

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

Nunalleq, a village in what’s today southwest Alaska, seemed to have thrived during the Little Ice Age. How did this village manage to survive and prosper during this time period? And what caused this period of climate change in the...

The climate of the Sahara was completely different thousands of years ago. And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made...

The Wrangel Island mammoths would end up being the final survivors of a once-widespread genus. In their final years, after having thrived in many parts of the world for millions of years, the very last mammoths that ever lived...

For decades, scientists have been studying the cause of the Younger Dryas, and trying to figure out if something like it could happen again. And it turns out that what caused this event is the subject of a heated debate.

You'd think that the Northern and Southern Hemispheres would be basically symmetrical -- that since our planet is a ball, the climate, temperature, and weather patterns would be the same on top as on the bottom. But there are some...

Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

There are wild hybridizations happening all the time! Here are five weird and wild hybrids that aren't just cool but could teach us something too. Hosted by: Hank Green (he/him) 0:00 Intro 1:06 Arctic Oddballs 3:43 Bouncing Baby Bears...

Plants make oxygen using photosynthesis, but what happens to the air when those trees drop their leaves in winter?

Today, Jessi and Sam the Bat take a look at constellations. Humans have been looking up at the sky for a long time and seeing all kinds of pictures hidden in the stars!

Romantic relationships are complicated. This collection of episodes follows Andy and Jordan's love story through attraction, love, and heartbreak.

How to think about this 4d number system in our 3d space.

Plants make oxygen using photosynthesis, but what happens to the air when those trees drop their leaves in winter?

The ancestors of modern horses became so successful that they spread all over the world, to Europe, Asia, South America, and Africa. But in their native range of North America, they'll vanish for 10,000 years. Until another strange...

Photographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change.

December has the longest solar days (noon-to-noon) because of the weird way a combination of the axial tilt of the earth and the eccentricity of its elliptical orbit conspire in December. Perihelion + Solstices = Long Days.

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and...

Ever wonder what seasons are like on other planets? Astronomers are beginning to find out, and SciShow Space explains how they know, what causes the change in seasons, and what 'summer' might mean on distant worlds.
