This video description is brought to you by language. But how long have humans been able to use our gift of gab? The answer is a lot more complicated than you might think. From studying fossil brains and ear bones to DNA migration...

From our deepest origins in Africa all the way to the Americas, by looking at the fossils and archaeological materials we have been able to trace the path our ancestors took during the short window of time when we took over the world.

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.

The hardened residue scraped off your teeth at the dentist is called your dental calculus, and your dental calculus is the only part of your body that actually fossilizes while you’re alive! And scientists have figured out how to study &...

Once upon a time, we coexisted with other human species. And there’s one place on Earth that may have taught us more about that than any other single site.

Scientists are sometimes deemed objective observers of the world in which we live, but that’s not entirely true. They’re still human and can find themselves victim to fraudsters just like the lot of us.

Nowadays, we're pretty confident about how the dinosaurs died out, but there are still other extinctions throughout Earth's history, some big, some small, that remain unsolved.

On the genetic level, we're not all that different from chimps. But those small differences in DNA can have massive effects. Learn what makes us truly different from chimpanzees in this new episode of SciShow!

Hank brings us some late-breaking news from the genus Homo - a team of scientists has sequenced the genome of the Denisova hominin, the latest member to be added to the human family tree.

Hank serves up a buffet of news items that includes an approximate date for the end of everything, scientific proof that when it comes to sex bigger IS better, and a look behind how the London Olympics are going green. Bon appetit!

In just the last century, we've made an astounding amount of scientific progress. And thanks to some of that progress, we can now share 10 of those discoveries with you in a video on the internet!

Sharing the results of a massive, worldwide study, geneticist Svante Pääbo shows the DNA proof that early humans mated with Neanderthals after we moved out of Africa. (Yes, many of us have Neanderthal DNA.) He also shows how a tiny bone...

Scientists estimate that about 2% of our DNA is from Neanderthals. In this week, the journal Cell showed what those Neanderthal DNA do to our genome.

Hank goes head-to-head with the Brain Scoop’s Emily Graslie to match wits about springs, hoaxes, and human evolution!

Once upon a time, we coexisted with other human species. And there’s one place on Earth that may have taught us more about that than any other single site.

Hank and the gang return with SciShow Quiz Show, where Sci Show's resident geniuses compete to win prizes for our subscribers!

Humanity has changed a lot since the days of our ancestral species, and we have continued evolution to look forward to as well.

Hank takes us to the island of Flores, where a race of wee people walked beside pygmy elephants, dragons and giant tortoises; they lived underground and had simple lives...

The same enzyme that used to save us is now killing us because the body reactions it catalyzes now cause more harm than good.

Hank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development...
