    The first era of our current eon, the Paleozoic Era, is probably the most deceptively fascinating time in Earth’s history. With near constant revolutions in life, punctuated by catastrophic extinctions, it is also one of the most chaotic.

    Correction! At 9:19, we erroneously refer to Dimetrodon as an herbivore. It was definitely a carnivore. We even made a whole video about Dimetrodon and their carnivorous ways in a previous episode: https://youtu.be/SR3OOP9mImI Thanks to everyone who pointed out our error!

    Thanks to Studio 252mya for their illustrations. You can find more of their work here: https://252mya.com/licensing

    The lobe finned fish that started walking on land... did it spread from one area or was it convergent evolution that lead to global abundance of that adaptation?
