Out-of-date Gnathostomata lecture on YouTube by Idaho curator Brandon Peecook
https://www.youtube.com/watch?v=WcYg0ZOb3uI
Brandon Peecook,
Curator of Vertebrate Paleontology at the Idaho Museum of Natural History produced a YouTube video on jawed fishes. Unfortunately the lecture is based on out-dated textbooks and lectures. Peecook teaches a single origin for jaws. That is incorrect.
A competing analysis that tests more taxa at the generic level,
is lhe large reptile tree (LRT, 2340 taxa), where jaws evolved more than once. Peecook presents a simple ladder of evolution. He’s young. That happens.
The LRT lumps and splits the origin of every fish structures from teeth to fins recovering several convergent lines. And that was only a few years ago, toward the end of adding fish to the LRT.

The question is
why would you pay a university tuition for invalid data – that you would be tested on – and expected to provide the wrong answer on the final exam?
Paleontology has never been known to be up-to-date. So the blame here is cast widely, not just on this curator.
