Welcome to Episode 100! Today's special episode will be a deep dive into the world of the Ediacaran biota. We'll explore the early days of the Ediacaran, and the changing world that would give rise to the earliest animal-like organisms. Then, we'll follow their evolution through the Avalon, the White Sea, and the Nama time periods to see how this Ediacaran life evolves, diversifies, and eventually responds to the presence of new forms in the early Cambrian. In this way, we will learn how the Ediacaran biota set the stage for all animal life that would follow after them.
