Twitter people who like to say that "Gould is a charlatan who didn't contribute anything to evolutionary theory," I have a question for you:

Who is your favorite evolutionary paleontologist, and why?

Hard Mode: Not Lyell
Impossible Mode: They have to be Alive

Since you guys know about these things, I'll go first! Mine is Ian Tattersall cause he has done a great job at addressing a number of Bayesian uncertantities in highlighting the importance of hard-tissue morphologies as they relate to delineating neontological species boundaries.

His point is that there are a variety of living populations exhibiting the same skeletal morphology that are *separate species*. Meaning that if you see substantive skeletal differences in the fossil record, there is a higher probability you are looking at different species.
