How and why the giraffe's neck emerged in the first place has been a mystery that generations of biologists have argued over – one that has made us reconsider our understanding of how evolution actually works over and over again.

How did ants take over the world? Well, it looks like they didn’t achieve world domination all by themselves. They may have just been riding the wave of a totally different evolutionary explosion.

What graptolites tell us is a story of incredible changes in the ocean, of periods where the oceans became poisonous and suffocating before eventually clearing up again. They unlock extinctions and recoveries that scientists didn't see....

Turns out, instead of having bats to thank for the existence of butterflies, the groups we should actually be thanking are…bees and beans.

To get fire, which exists only on Earth, it took billions of years of photosynthesis – which means fire can’t exist without life. And fire and life have been shaping each other ever since.

Tiny exoskeleton fragments may have allowed some of the most important microbes in the planet’s history to set sail out into the open ocean and change the world forever.

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...

What are animal-like fossils doing in rocks a billion years old, and what does that mean for our understanding of their evolution and geologic time itself? Turns out, there might've been a long, slow-burning fuse that ultimately ignited...

While we think we know a lot about dinosaurs – like how they moved and what they ate – for a long time, we haven’t been able to ID one seemingly basic thing about their biology... Which are males and which are females?

For some, the rise and spread of venomous elapids was just another challenge to adapt to. For others, it was a catastrophe of almost apocalyptic proportions. And we humans are no exception, because it seems that when elapids slithered...

We spend a lot of time here on Eons looking backwards into deep time, visiting ancient chapters of our planet’s history. But this time, we’re taking a look towards the deep future. After all, the story is far from over.

It would take decades for paleontologists to realize that maybe there wasn’t just one so-called "cradle of humankind," and realize that maybe they’d been asking the wrong question all along.

Researchers have discovered a piece of a weird, but critical, time in the deep past…a time when the first-ever mass extinction may have turned Planet Earth into Sponge World.

While the eruptions of the volcanoes along the Mid-Atlantic Ridge usually don't trouble us, their birth was once responsible for ripping a supercontinent apart and creating the Atlantic Ocean that we know today.

We need to talk about the biggest break-up of all-time: the break-up of the supercontinent Pangea, and how, ultimately, when India smashed back into Asia, it traded one form of evolutionary isolation for another.

Spiders and their ancestors have been driving an arms race that began before either stepped foot onto land and resulted in the first powered flight on Earth. But how did this competition of webs versus wings drive such a massive...

How did a relative of the red panda end up in North America? What can this tell us about how long ago – and how many times – North America was connected to Europe and Asia?

In this SciShow Kids compilation, Jessi and Squeaks learn all about dinosaurs—when they lived, how they died, and how we know so much about them.<b<br/>r/>

We know that fossils are fragile, and volcanoes are destructive. So you wouldn't think that volcanoes are really any help when preserving fossils... but you'd be wrong! From the Laetoli Footprints to the Blue Lake Rhino, here are five...

The same technology that helps you rack up kills in your favorite FPS games also helps paleontologists solve million-year-old mysteries. Thanks to Dr. Anne Kort for helping us with this video!

Natural history is full of living things that were long thought to have gone extinct only to show up again, alive and well. Paleontologists have a word for these kinds of organisms: They call them Lazarus taxa.

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...

Sixty-six million years ago, near what’s now the Yucatán Peninsula, a juvenile sauropod feasted on horsetail plants on a riverbank. Earth was a tropical planet. Behemoth and tiny dinosaurs alike soared its skies and roamed its lands...

Recently, a group of scientists have declared that the start of the Anthropocene, the time of outsize human influence on Earth, to be Crawford Lake in Canada. But how can a time be a place? We'll explain, and maybe grab some maple...
