This is why I enjoy the HN comments. Although, I should probably be upset that you sent me down a Wikipedia rabbit hole (the theory is interesting!): https://en.wikipedia.org/wiki/Ungulate#Cetacean_evolution

This is a real TIL moment right there. Good job, HN. :)

Although, from Wikipedia:

> As a descriptive term, "ungulate" normally excludes cetaceans (whales, dolphins, porpoises), as they do not possess most of the typical morphological characteristics of ungulates, but recent discoveries indicate that they are descended from early artiodactyls.

What the what?! I stand corrected, though how I'm standing with my mind splattered across the ceiling, I'm not sure...

I don't think whales are considered ungulates, it is just that ungulate is no longer considered a monophyletic category (but cetartiodactyla is).

Are you proposing that this creature might be a hippo, or were you showing off your knowledge of recent re-orderization? Do non-cetacean ungulates call like cetaceans?
