How Blood Evolved (Many Times)
Blood is one of the most revolutionary features in our evolutionary history. Over hundreds of millions of years, the way in which blood does its job has changed over and over again. As a result, we animals have our familiar red blood. But also blue blood. And purple, and green, and even white.

The Humans That Lived Before Us
As more and more fossil ancestors have been found, our genus has become more and more inclusive, incorporating more members that look less like us, Homo sapiens. By getting to know these other hominins--the ones who came before us--we can start to answer some big questions about what it essentially means to be human.

The Island of Shrinking Mammoths
The mammoths fossils found on the Channel Islands off the coast of southern California are much smaller than their relatives found on the mainland. They were so small that they came to be seen as their own species. How did they get there? And why were they so small?

The Evolution of the Heart (A Love Story)
In order to understand where hearts came from, we have to go back to the earliest common ancestor of everything that has a heart. It took hundreds of millions of years, and countless different iterations of the same basic structure to lead to the heart that you have today.

How 7,000 Years of Epic Floods Changed the World
Strange geologic landmarks in the Pacific Northwest are the lingering remains of a mystery that took nearly half a century to solve. These features turned out to be a result one of the most powerful and bizarre episodes in geologic history: this region experienced dozens of major, devastating floods over the course of more than 7,000 years.

The Island of Huge Hamsters and Giant Owls
Back in the late Miocene epoch, there was an island--or maybe a group of islands-- in the Mediterranean Sea that was populated with fantastic giant beasts. It’s a lesson in the very strange, but very real, powers of natural selection.

When Giant Scorpions Swarmed the Seas
Sea scorpions thrived for 200 million years, coming in a wide variety of shapes and sizes. Over time, they developed a number of adaptations--from crushing claws to flattened tails for swimming. And some of them adapted by getting so big that they still hold the record as the largest arthropods of all time.

The Ghostly Origins of the Big Cats
All of today’s big cat species evolved less than 11 million years ago and yet their evolutionary history remains an almost total mystery. But scientists have recently discovered a major clue about the origins of the big cats, one that could provide a whole new starting place for solving this puzzle.

The History of Climate Cycles (and the Woolly Rhino) Explained
Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

The Hellacious Lives of the "Hell Pigs"
Despite the name, we don’t know where the so-called “hell pigs” belong in the mammalian family tree. They walked on hooves, like pigs do, but had longer legs, almost like deer. They had hunched backs, a bit like rhinos or bison. But as is often, if not always, the case, there is some evolutionary method to this anatomical madness.

How Evolution Works (And How We Figured It Out)
As a scientific concept, evolution was revolutionary when it was first introduced. With the help of all three of our hosts and the Smithsonian National Museum of Natural History’s new Deep Time Hall, we’ll try to explain how evolution actually works and how we came to understand it.

When the Synapsids Struck Back
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 the time when the synapsids struck back.

When We Met Other Human Species
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.

When Giant Lemurs Ruled Madagascar
Just a few thousand years ago, the island of Madagascar was inhabited by giant lemurs. How did such a diverse group of primates evolve in the first place, and how did they help shape the unique environments of Madagascar? And how did they get winnowed down, leaving only their smaller relatives behind?

The Case of the Dinosaur Egg Thief
Paleontologists found a small theropod dinosaur skull right on top of a nest of eggs that were believed to belong to a plant-eating dinosaur. Instead of being the nest robbers that they were originally thought to be, raptors like this one would reveal themselves to actually be caring parents.

When Hobbits Were Real
Its discoverers named it Homo floresiensis, but it’s often called “the hobbit” for its short stature and oddly proportioned feet. And it’s been at the center of a major controversy in the field ever since. Was it its own species? Or was it really just one of us? Or, could it even have descended from a whole lineage of hominins that we don’t even know about?

Were These Monsters Inspired by Fossils?
People have been discovering the traces and remains of prehistoric creatures for thousands of years. And they’ve also probably been telling stories about fantastic beasts since language became a thing. So, is it possible that the monsters that populate our myths and legends were influenced by the fossil record?

Why Male Mammoths Lost the Game
Woolly mammoths, our favorite ice age proboscidean, disappeared from Europe and North America at the end of the last ice age, about 10,000 years ago. Today, we’ve teamed up with TierZoo to solve one of the mysteries about these charismatic megafauna: why do most remains of mammoths found in the fossil record turn out to be male?
