Our Ancient Human Cousins!

♪Intro♪ Oh, hi there! Squeaks and I were just checking our e-mail, and it looks like you have a message from your sister. (Squeaks squeaks) Hm, I wonder what it is… Oooh, it’s your family tree! There are his grandparents, then his parents in the middle, and then their kids — including Squeaks and his […]

When Hobbits Were Real

We’d like to thank Raycon wireless earphones for supporting PBS. In October 2004, our understanding of the human family tree was turned upside down. That’s when anthropologists reported that they’d discovered the bones of a tiny, unknown hominin, on the Indonesian island of Flores. This little creature stood only about a meter tall and had […]

What Your Family History Can’t Tell You

Thanks to the National Institutes of Health’s National Human Genome Research Institute for supporting this episode of SciShow. [♪ INTRO] The first time you visit a new doctor, they’ll probably ask about your family history. Everything from heart disease to certain cancers to type 2 diabetes—if one of your close relatives has had it, they […]

How the Squid Lost Its Shell

500 million years ago, back in the Cambrian Period, a pioneering little mollusk floated up off the ocean floor. It had developed a way to use its defensive shell for a whole new purpose — buoyancy. It turned out that by filling its shell with gas, this mollusk could literally reach new heights, gaining a […]

The Texas Vampires

The Texas Vampires. It sounds like the name of a biker gang from a bad TV show. It sounds like a 90’s rave club in Austin wherever people think that eyeliner makes you look edgy. It sounds like a drama in which Jonah Hill and Nic Cage play two men from Houston who have to […]

How Sloths Went From the Seas to the Trees

8 million years ago, off the coast of Peru, a large mammal used its powerful claws to pull itself along the ocean floor, holding fast against the waves as it foraged for seagrass. 5 million years ago, a similar creature was burrowing underground in Argentina, digging burrows so massive that you could walk right into […]

The Missing Link That Wasn’t

It’s 1912, and an amateur archaeologist named Charles Dawson came forward with a discovery that almost changed our understanding of human evolution. Almost. Dawson’s find was some unusual human-like skull fragments, and he showed them to the Keeper of Geology at the British Museum, Sir Arthur Smith Woodward. He explained that the fragments were given […]

Your Place in the Primate Family Tree

Hey there, Kallie here to remind you that Eons has some cool stickers for sale over at DFTBA.com, link in the description. Thanks for watching and, on with the show. Would you recognize your earliest primate ancestor if you met it face to face? What if it didn’t look like a monkey, or an ape, […]

How DNA Analysis Led Police to the Golden State Killer

[INTRO ♪] Back in the ‘70s and ‘80s, a man known as the ‘Golden State killer’ terrorized California, committing a string of more than 100 burglaries, 45 rapes, and a dozen murders. Definitely a bad dude. Even though the police had DNA evidence from crime scenes, it never matched any DNA records on file, so […]

The Humans That Lived Before Us

For about a million years in the early Pleistocene Epoch — from about 2.4 million to 1.4 million years ago — it was a really exciting time to be a hominin. Hominins, you’ll recall, are the group of human ancestors that are more closely related to us than to chimps and bonobos. During this million-year […]
