The Common Descent Podcast

Happy Snake Month!

Some of the most fascinating, famous, and dangerous snakes on the planet belong to the family Viperidae. Vipers include some of the world’s most specialized ambush hunters, and they are one of the most diverse and successful groups of snakes. This episode, we take a tour through the many visages of vipers, we explore their unique adaptations from head to tail, and we investigate the deep history that led them to their incredible modern success.

In the news: colorful crocs, pregnant mussels, tiny migration, and surprising snakes.

Happy Croc Month!

Most living crocodilian species look pretty similar overall – that’s why there are so many tips for telling alligators from crocodiles – but one group really stands out with their bulging eyes and remarkably slender snouts. This episode, we explore the various features and habits that make gharials unique among crocs, and which have caused no end of confusion for scientists trying to sort out their evolutionary history. And, of course, we’ll take a trip into the fossil record to visit some of the most extraordinary long-snouted crocs of the distant past.

In the news: hagfish eyes, dinosaur arms, fungal spores, and fishing dinosaurs.

Cycads are cousins of conifers, and although they can be found throughout the modern tropics, they are often considered a visual indicator of prehistory. This episode, Aly joins us to explore what sets cycads apart from other plants, what we know of their deep history, and whether they truly deserve their reputation as dinosaur food.

In the news: toothless crocs, Arctic mammals, turtle relations, and crater life.
