Episode #11 The Origin of Human Anatomy is in Old Dead Fish with John Long

"You're a fish!"
Turns out that's not an insult, it's the truth! Professor John Long will explain why this is true AND discusses the origins of sex! And then he'll ride off on his motorcycle...

Episode #11 The Origin of Human Anatomy is in Old Dead Fish with John Long

John Long

Strategic Professor of Paleontology at Flinders University

 

At the young age of 7, John Long stumbled upon a Devonian trilobite in a quarry outside of Melbourne, Australia. Learning that where he was standing had once been an ocean really blew his young mind. 

That was only the beginning, and John soon found that within the fishes of the Devonian he could see the "roadmap to the human body plan" - Imbedded in ancient fish is the origin of all the anatomical systems that make us human: arms, legs, jaws, teeth, and behaviors like breathing and complex sexual reproduction. In other words: If you trace human evolution back far enough, we are all fish.

John's work with the FIN-ger bones of Elpistostege has made it the new "Poster Boy" of Stem-Tetrapods and brings us one step closer to identifying our Great Great Great Great Great Great (...etc.) Grandfather Fish who used it's proto-limbs to transition from water to land.

John introduces Materpiscis attenboroughi (yes, it's named after David Attenborough)

 

Over the past 30 years John's extensive collections of pristine specimens from the  Gogo Formation have allowed for more discoveries, including the origins of sexual reproduction. The specimen of Materpiscis (translates to "Mother Fish") held evidence of internal fertilization and hence the first fossil evidence of sex, and is outlined in his appropriately named book Dawn of the Deed.

John is the auther of nearly 30 books, including Children's books!
