We will discuss the commentary by Mark Pagel on the recent Nature paper by Louca and Pennell about how much information exists about speciation and extinction rates in extant time trees.

Sep. 10, 2020

Today we will discuss this response to Louca and Pennell by Morlon, Hartig, and Robin: Prior hypotheses or regularization allow inference of diversification histories from extant timetrees.
