The Common Descent Podcast

Welcome ... to Spookulative Evolution. It’s Spook-E Season! All throughout October, we pick monsters from myth and media and speculate 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 time, we pull an extra-dimensional horror from the world of video games. What might lead natural processes to develop creepy-crawly parasite-hats? Our creates to create this time: Headcrabs.

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.

Nearly 400 million years ago, an unusual group of fish gave rise to the first land-dwelling vertebrates. Since then, their descendants have repeatedly moved back into the water. This episode, we explore the many ways these species adapt to the challenges of turning a terrestrial body into one that can survive at sea, and we investigate some of the most famous and confusing cases from the fossil record. In the news: post-extinction oceans, croc eggs, damaged dino tails, and meat-eating dung beetles.

The dome-headed dinosaurs are some of the most iconic ancient reptiles, but they’re surprisingly unexplored compared to other dinos. This episode, we explore what makes these dinosaurs unique, what limits our understanding of them, and the many confounding mysteries that paleontologists have been scratching their heads over, including the question of what exactly they were doing with those thick heads. In the news: the I Know Dino children’s book, giant reptile locomotion, and dinosaur hooves.

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 Monsters of Nintendo. This episode, we pluck precious partners from the soil. What could be the evolutionary background of tiny and colorful workers that blend the features of plants and animals? Our creatures to create this time: Pikmin.

Generally speaking, it’s not a good idea to mess with ants. But several lineages of animals have evolved to be ant-eating specialists. This episode, we discuss anteaters, the suite of adaptations that allow them to focus on ant-eating, and the variety of other species that have evolved similar adaptations for the same purpose. We explore the evolutionary history of ant-eating mammals and even dinosaurs through the fossil record and genetic evidence. In the news: butt-drags, ancient leeches, Neanderthal tracks, and spider genomes.
