The Common Descent Podcast episodes

November 08 Episode 256 - Predatory Lures
Why spend all that effort chasing after prey when you could just convince them to come to you? This episode, we explore the many and varied ways that predators lure their prey, from dangling lights to strategically-placed bait. And we’ll discuss the evolutionary pros and cons of this life strategy, and how all sorts of animals – and plants – make the most of it.
In the news: big Jurassic bugs, big Jurassic belemnites, ocean amphibians, and aquatic anatomy.

October 31 Cute-E - Tribbles
Welcome … to Cute-E!
During our Spook-E series, we speculate on the evolution of monsters from myth and popular media, but we leave out fiction’s more adorable creatures. In Cute-E, we choose cuddlier critters and discuss how they – or something like them – could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Aliens!
This episode, we’re overrun with cuteness! What evolutionary history could lead to pesky swarms of irresistibly adorable fuzzballs? Our creatures to create this time: Tribbles.

October 25 Episode 255 - Plant Origins
Here on our blue-and-green planet, the green is plants. This episode, Aly joins us again to explore the beginnings of this all-important group of life. We’ll discuss which ancestors gave rise to true plants, what the fossil record tells us about the timing of this momentous event, and the array of key adaptations that allowed plants to join their fungus and animal cousins up on dry land.
In the news: mosasaurs, more mosasaurs, Jurassic mammals, and horned dinosaurs.

October 11 Episode 254 - Abelisaurs
During the Cretaceous Period, while tyrannosaurs stomped around the northern continents, the less famous abelisaurs were the top predatory dinosaurs of the south. This episode, we piece together the history and diversity of these predators, and we explore what they were doing with their bulldog faces, tiny arms, and in some cases, horned faces.
In the news: plesiosaur vomit, seaweed snacks, bat evolution, and flying dinosaurs.

September 13 Episode 252 - The Ice Age
About 10% of the Earth’s land surface is currently covered in persistent glacial ice, but for most of Earth history, that number was much closer to zero. This episode, we explore what happens when ice overtakes our planet and how we investigate icy conditions of the distant past, and we’ll take a close look at the most recent (and ongoing) global climate event that we commonly call the Ice Age.
In the news: distant space objects, snake embryos, Jurassic chirps, and polar dinosaur nests.
