The Common Descent Podcast

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.

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.

Eels are long-bodied fish found in a variety of aquatic habitats, famous for their unusual body plans, distinctive life cycles, and occasional anatomical oddities like extra jaws. This episode, we’re joined by special guest Shay Maden to discuss the diversity, evolution, and fossil history of the true eels of the Order Anguilliformes, and we’ll also make mention of other famous “eels” and the repeated evolution of the eel-like body shape. In the news: dog brains, giant beans, marine crocs, and opening oceans.

Meredith Johnson, host of the Leakey Foundation's 'Origin Stories,' dives into the art of storytelling in science communication. She emphasizes how relatable narratives help explain human evolution, making complex concepts accessible. The discussion also covers engaging audiences through online communities and the excitement of connecting with listeners. They explore the challenges of building public trust in science and the innovative blending of storytelling with scientific facts, further encouraging collaboration among podcasters.

Some animals are specialists at eating particularly tough foods like shells, seeds, and bones. Adaptations for a durophagous diet come in many forms in almost all major groups of life. This episode, we discuss how so many animals tackle tough foods, what behaviors and anatomy help them to do it, and the importance of durophagy for understanding fossils and the history of Earth ecosystems. In the news: fossil boas, walking fish, cooked birds, and early arthropods.

Leaves. They’re everywhere. They’re the main photosynthesizing organs of plants, and they’re the main source of green on our green-and-blue planet. Leaves come in a truly dizzying variety of shapes, sizes, and specialized functions, and their early evolution laid the foundation for terrestrial ecosystems as we know them. This episode, Aly joins us yet again to talk about the anatomy and diversity of leaves and the incredible information we can learn from leaves in the fossil record. In the news: croc cousins, horned dinosaurs, dinosaur myths, and fish brains.
