Spook-E - Salamanders
Welcome ... to Spookulative Evolution.
October is Spook-E Season on Common Descent! Each episode, we pick monsters from fiction and fable and ponder 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 Tiny Monsters.
This episode, things heat up a bit. What selective pressures might lead to the evolution of skittering creatures with a fondness for fire? Our creatures to create this time: the mythical Salamanders.

Episode 202 - Fungi and Animals
It’s the final part of our fungal trilogy!
Fungi and animals interact in a wide variety of ways, from parasitism to partnership to predation. This episode, we explore how fungi and animals have evolved alongside each other and the adaptations they have developed to take advantage of each other, and we’ll examine how far back we can find these fungus-animal interactions in the fossil record.
In the news: pterosaur feet, sauropod tails, a Cretaceous crater, and fossil fireflies.

Episode 201 - Fungi and Plants
Aly Baumgartner, a paleobotanist focused on plant-fungi interactions, dives into the fascinating relationships between fungi and plants. She discusses how these organisms collaborate and compete throughout evolutionary history, shaping ecosystems globally. The conversation covers vital roles like mycorrhizae in nutrient exchange, the complex networks of mycelial communication, and even the intriguing phenomenon of myco-heterotrophy in certain plants. This lively discussion is packed with insights into the delicate balance of nature and the hidden world beneath our feet.

Episode 199 - Hibernation
Sometimes, an animal just needs to power down and wait. Many animals exhibit some form of torpor, including the long-term dormancy of hibernation. This episode, we explore how these species adjust their body functions, we discuss the pros and cons of this surprisingly common biological strategy, and we’ll take a look at what we know about the evolutionary history and fossil record of hibernation.
In the news: walrus diets, ancient weapons, grape evolution, and fossil tardigrades.
