Before the Cambrian Explosion, there was … a lot of weird squishy organisms. The Ediacaran, the subject of this episode, was a period just before the Cambrian. During this time we see the rise of a very odd and interesting group of organisms known as the Ediacaran Biota.
In this episode we discuss an interesting and important group of ancient armored fish; Placoderms! We discuss some of their wide variety, their evolutionary significance, and focus a bit on their biggest and most famous member: Dunkleosteus.
February 12th is Darwin Day! On this day, biology-nerds like us – and our special guest, Dr. Sarah Bray! – celebrate the birthday and life achievements of the scientist who ushered in our modern understanding of the subjects that underlie just about every topic we discuss on this podcast: Charles Darwin.
It’s the first episode of 2018!
