There was a group of hominins, those creatures more closely related to us than to chimpanzees, that did take a different, parallel journey from our ancestors. Our paths ran beside each other - and potentially even crossed at times - but...

In 2003, a fossil belonging to a mammaliaform was discovered in an ancient lakebed in what's now China. It was an almost complete skeleton the size of a platypus, a find that complicated the history of mammaliaforms. It painted a picture...

Unlike in fiction, giant whales do not emerge fully-formed from the ocean deep. So, where did Livyatan melvillei come from? How did such a large predator live? And what caused the titan to die out? The answer may lie in an appetite so...

Great white sharks have nothing on these terrifying jaws. Some marine animals have adaptations that turn their jaws into harpoons, fishing nets, claw machines, and more.<b<br/>r/>

You may have heard of the Hobbits -- no, not the Tolkien ones. Our cousins, Homo floresiensis! But have you ever wondered why this enigmatic mini species was so little? Let's talk about the decades of research into what made the...

Why do we have wisdom teeth? They're just going to come in wrong and cause problems. Wisdom teeth are a souvenir from our early human ancestors, and we actually understand less about them than you might think.

Smilodon the saber-toothed cat had really big teeth! Join Jessi and Squeaks and learn all about how fossils can tell us how these Ice Age animals lived.

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!

Have you ever thought about why we humans have noses that stick out? Turns out, there's been a big story about human evolution right... under your nose.

You would think that without dentists and fluoride mouthwash, early humans would have terrible teeth. But tooth decay depends on access to sugars and starches -- meaning most early humans had decent teeth up until the Agricultural...

It's that time of year where we round up all our favorite science discoveries of the year, and today, we're talking fossils. From a wild mosasaur with screwdriver teeth, to glittery gold fossils, and even a mammal-versus-reptile fight to...

Platypuses are so funny, it looks like someone made them up as a joke. But they're real animals! Join Jessi and Squeaks to learn about how amazing platypuses really are!

When you're enjoying an intimate moment with that special someone, the peanut butter and jelly sandwich you ate for lunch is probably the last thing on your mind. But sexually transmitted allergens are a thing, and nut allergies aren't...

We often think of dinosaurs as either preying on other dinos or mammals, or as plant-eaters -- but in ecosystems today, those aren’t the only two options. So why would we expect dinosaurs to have only been carnivores or herbivores, with...

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.

Synapsids were the world’s first-ever terrestrial megafauna but the vast majority of these giants were doomed to extinction. However some lived on, keeping a low profile among the dinosaurs. And now our world is the way it is because of...

In Australia, evolution built a family of deadly predators by taking a group of cute, harmless herbivores and turning them murderous.

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.

These hyaenodonts gave the world some of its largest terrestrial, carnivorous mammals ever known. And while these behemoths were the apex predators of their time, they were no match for a changing world.

All told, the Arctic in the Cretaceous Period was a rough place to live, especially in winter. And yet, the fossils of many kinds of dinosaurs have been discovered there. So how were they able to survive in this harsh environment?

While dinosaurs were dominating the land, the metriorhynchids were thriving in the seas. But taking that plunge wasn’t easy because it takes a very special set of traits to fully dedicate yourself to life at sea.

Early primates not only lived in North America -- our primate family tree actually originated here! So what happened to those early relatives of ours?

Paleontologists have spent the better part of two decades debating whether Coelophysis ate its own kind. It turns out, the evidence that scientists have had to study in order to answer that question includes some of the strangest and...
