We all belong to the only group of hominins on the planet today. But we weren’t always alone. 100,000 years ago, Eurasia was home to other hominin species, some of which we know our ancestors met, and spent some quality time with.

These relatives of ours lived in Eurasia for more than 300,000 years. They were expert toolmakers, using materials like stone, wood, and animal bone. They were also skilled hunters and foragers, and may even have created cave art. So...

After watching Game of Thrones or playing DND, you might wonder if Dire Wolves were actually real. Turns out, these were real animals that lived during the last Ice Age, but they weren't actually...wolves? Join Hank Green and learn what...

During most of the past 2 million years or so, there were several species of hominins on Earth at any given time. Like, you might be familiar with our famous extinct cousins, the Neanderthals. But since 2010 we’ve been uncovering...

Although polar bears and grizzly bears aren't all that similar and are definitely separate species, they can interbreed and create fertile offspring in the wild. Hank brings us the story of these misfit bears, which he likes to call...

We all know about inter species animal hybrids - Napoleon Dynamite's favorite animal, the liger, is a typical example. But could a human and our closest primate relative the chimpanzee also breed a living hybrid? Hank explores this ......

Delve into the world of dingoes, from their cultural significance to the challenges they face in modern Australia.

Neanderthals coexisted with modern humans for tens of thousands of years, and the two groups certainly met. Evidence shows that Homo sapiens not only procreated with Neanderthals - they also slew and ate them.

What is the difference between a population, community and ecosystem and species? What defines different populations of the same species? What factors lead to separate populations? In this program explains that members of the same...
