Cool figure made with the help of #phytools in "Evolution of thumbnails across Rodentia" by @rafaelamissagia et al. in @ScienceMagazine. I especially appreciate that the authors acknowledged using phytools for the plots, something that's often overlooked! doi.org/10.1126/scienc…

I'm not sure how, but I almost completely forgot I did this in #phytools even though it was only, like, two weeks ago: "A Pagel '94 type correlation model with one binary trait and one continuous character" using the discretized diffusion approximation (blog.phytools.org/2025/07/a-page…).
