@T.j_Runyon @NLENTS - Crocodile phylogeny would be a very good context for discussing the mathematical basis for building trees/nested hierarchies. Not going into all the details of the math (which I know to be highly technical), but more in the sense of its use of an algorithm to select the most probable tree, the null hypothesis (no tree) is excluded by statistical significance testing, etc.
A lot of folks think that it’s all an exercise in choosing to “see” a tree based on nothing more than a pre-existing bias in the realm of biology. Seeing how it really works with crocodiles would be quite instructive.
I’m sure there are many other aspects of evolutionary biology that could be illuminated by the study of crocodile phylogeny. So I would be on-board for such an office hour.
