Episode 77 - Fins to Feet: The Fish-Tetrapod Transition
Saturday Dec 28, 2019
Saturday Dec 28, 2019
Happy New Year!
As we transition into a new decade, this episode is about one of the most important and incredible transitions in the evolutionary history of life. In the Late Devonian, one particular group of bony fish spent many millions of years experimenting with new forms of fins, skulls, and lifestyles, ultimately giving rise to the first land-dwelling vertebrates and setting the stage for 300 million years of continental dominance.
In the news: the earliest penguins, ancient whale swimming, dinosaur lice, and really old brains.

You jumped from the Carboniferous to the Cretaceous and back again real quick. I'm assuming the Cretaceous was a slip of the tongue.
