About this episode

This episode explores the evolutionary history of animals from the split of metazoans to the rise of amniotes, focusing on key morphological developments.

A journey through the evolutionary history of animals, beginning with the split of the metazoans from protists about 760 million years ago and ending with the rise of the amniotes about 340 million years ago. The focus is the development of key morphological traits necessary for more complex animal forms, including the origin of true tissues, bilaterial symmetry, the complete gut, the coelom, internal skeletons, and limbs. We conclude with an analysis of key adaptions that allowed amniotes to life in a wider range of terrestrial habitats. Recommended pre-listening is Episode 155: Embryology and Development and Episode 157: The Geologic Time Scale.
