The Common Descent Podcast

Large, herbivorous mammals come in many shapes and sizes, but few are as famously unusual as camels. This episode, we explore the surprising adaptations of Old World and New World camelids, from the dromedaries of Middle Eastern deserts to the llamas of the Andean highlands. Then, we take a tour through their fossil record to investigate the many forms this family took on the way to our modern diversity.

In the news: stomach stones, aquatic reptiles, tiny dinosaurs, and a Poop Explosion.

In most animal species, there are differences in the anatomy, behavior, and lifestyle of male and female individuals. In this episode, we explore the incredible variety of these differences and the equally incredible blurry areas between the sexes, we investigate the evolutionary processes behind these features, and we examine the constant and confounding discussion about whether or not we can spot sexual dimorphism in the fossil record.

In the news: The Story of Birds, early snakes, and early archosaurs.

Felines come in all shapes and sizes, but only a handful of them are large enough and in charge enough to have earned the title of “Big Cats.” This episode, we’re joined by special guest Lindsay Nikole as we take a tour through the surprising diversity of the “official” and “unofficial” big cats, and we explore how their evolutionary past has shaped this impressive assortment of apex predators.
