EP1 How our deadliest parasite turned to the dark side Jan 11, 2022

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.

EP2 Primates vs Snakes (An Evolutionary Arms Race) Jan 19, 2022

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.

EP3 How the Rise of Social Insects Shrunk These Dinosaurs Jan 27, 2022

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 the occasional omnivore thrown in the mix?

EP4 How Vertebrates Got Teeth... And Lost Them Again Feb 08, 2022

As revolutionary as teeth were, they would go on to disappear in some groups of vertebrates. But why?

EP5 How Horses Went From Food To Friends Feb 16, 2022

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.

EP6 Why We Only Have Ten Toes (It's a Long Story) Feb 23, 2022

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!

EP24 How the Smallest Animal Got So Simple Apr 13, 2022

EP26 Why Sour May Be The Oldest Taste Apr 20, 2022

EP27 The Ancient Human Species With A Missing Body Apr 27, 2022

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?
