    Animals are many and varied, but one of the things nearly all of them share is that they start life off inside a small and special capsule complete with everything the growing embryo needs for protection and nutrition. In this episode, we discuss the diversity, evolution, and fossil history of Eggs.

  • Episode 81 – Metamorphosis

    Listen to Episode 81 on PodBean, Spotify, YouTube, or anywhere you’d like!

    All animals change as they get older. Typically these changes are slow and subtle, but many animals famously undergo sudden and dramatic changes from young to adult – caterpillars to butterflies; fry to fish; or tadpoles to frogs. In this episode, we discuss the diversity and history of the incredible phenomenon called Metamorphosis.

  • Episode 53 – The Baculum (Penis Bone)

    Listen to Episode 53 on PodBean, Spotify, YouTube, or that other place you get podcasts … you know the one!

    It’s been called the most diverse of all bones. It comes in an incredible variety of shapes and sizes, living and fossil, scattered across the mammalian family tree. It is clearly of evolutionary importance, yet its exact function still perplexes scientists to this day. It’s called the baculum, and it is found exclusively in mammalian penises.

  • Episode 44 – Hybridization

    Listen to Episode 44 on PodBean, Spotify, YouTube, or other podcast providers near you.

    In today’s episode we discuss the weird world of hybrids. The fact that different species of organisms sometimes breed has thrown a wrench into the scientific understanding of species and how they function for centuries. We won’t be solving that problem in this episode but we will cover how hybrids are made, why they’re made, how species stay separate, and what can happen when species (or other groups) interbreed.

  • Episode 33 – Ontogeny

    Listen to Episode 33 on PodBean, Spotify, YouTube, or a podcast provider near you!

    In this episode we discuss the process through which organisms develop throughout their lives, otherwise known as ontogeny. We’ll examine what ontogeny is, what it teaches us, and how we deal with it in the fossil record.
