Eons

Join hosts Michelle Barboza-Ramirez, Kallie Moore, and Blake de Pastino as they take you on a journey through the history of life on Earth. From the dawn of life in the Archaean Eon through the Mesozoic Era — the so-called “Age of Dinosaurs” -- right up to the end of the most recent Ice Age.

The Ancient Human Species With A Missing Body

7m 56s

Only a handful of Denisovan fossils have been identified. In the absence of actual body fossils, it’s impossible for us to reconstruct their morphology, right?

    The Ancient Human Species With A Missing Body

    S4 E28 - 7m 56s

    Only a handful of Denisovan fossils have been identified. In the absence of actual body fossils, it’s impossible for us to reconstruct their morphology, right?

  • Why Sour May Be The Oldest Taste: asset-mezzanine-16x9

    Why Sour May Be The Oldest Taste

    S4 E27 - 7m 2s

    While sour taste's original purpose was to warn vertebrates of danger, in a few animal groups, including us, its role has reversed. The taste of danger became something it was dangerous for us to avoid.

  • How the Smallest Animal Got So Simple: asset-mezzanine-16x9

    How the Smallest Animal Got So Simple

    S4 E26 - 6m 52s

    We tend to think that evolution only goes in one direction— toward getting bigger and more advanced. But that’s not always the case. This tiny, simple animal, the Myxozoans, (yes, animal!) evolved from something bigger and more complex.

  • The Sudden Rise of the First Colossal Animal: asset-mezzanine-16x9

    The Sudden Rise of the First Colossal Animal

    S4 E24 - 8m 44s

    A truly enormous ichthyosaur around the size of a modern sperm whale, reached its size within just a few million years of taking to the water - a blink of an eye in evolutionary time.

  • Why We Only Have Ten Toes (It's a Long Story): asset-mezzanine-16x9

    Why We Only Have Ten Toes (It's a Long Story)

    S4 E22 - 9m 12s

    Today, all mammals from humans to bats have five fingers or fewer. Yes, even whales, whose finger bones are hidden in their fins. Birds have four or fewer and amphibians get the best of both worlds, often having four digits on their “hands” and five on their “feet.” But no species of vertebrates have more than five digits, let alone eight!

  • How Horses Went From Food To Friends: asset-mezzanine-16x9

    How Horses Went From Food To Friends

    S4 E21 - 6m 32s

    Do our modern horses descend from just one domesticated population, or did it happen many times, in many places? Answering these questions has been tricky, as we’ve needed to bring together evidence from art, archaeology, and ancient DNA…Because, as it turns out, the history of humans and horses has been a pretty wild ride.

  • Primates vs Snakes (An Evolutionary Arms Race): asset-mezzanine-16x9

    Primates vs Snakes (An Evolutionary Arms Race)

    S4 E18 - 7m 53s

    The Snake Detection Hypothesis proposes that the ability to quickly spot and avoid snakes is deeply embedded in primates, including us - an evolutionary consequence of the danger snakes have posed to us over millions of years.

  • How Our Deadliest Parasite Turned To The Dark Side: asset-mezzanine-16x9

    How Our Deadliest Parasite Turned To The Dark Side

    S4 E17 - 8m 6s

    Around 10,000 years ago, somewhere in Africa, a microscopic parasite made a huge leap. With a little help from a mosquito, it left its animal host - probably a gorilla - and found its way to a new host: us.

  • When Pterosaurs Walked: asset-mezzanine-16x9

    When Pterosaurs Walked

    S4 E16 - 9m 38s

    If you know one thing about pterosaurs, it’s that they’re flyers. And while pterosaurs may be well-known for their domination of the skies in the Mesozoic Era, they didn’t live their entire lives in the air. So how did we figure this out? And what were they like when they finally came down?
