That's a real, physical book, people. @lukejharmon #Rstats press.princeton.edu/books/phylogen…

If anyone's interested, I just posted about accurate estimation of shape parameter α for Γ-distributed variation in the rate of discrete character evolution by edge using #phytools: blog.phytools.org/2026/05/estima….

I've been blogging (at blog.phytools.org) and speaking about this project for a while, but please check out our new pre-print here & let me know what you think: doi.org/10.64898/2026.…. Thanks! 7/7

... and a discrete-character-dependent multi-trend trended Brownian model, among other evolutionary scenarios. 6/7

With various colleagues including @lukejharmon I just published a new pre-print to @biorxivpreprint entitled "Unlocking a flexible set of phylogenetic models for discrete and continuous trait evolution using discretized stochastic diffusion." doi.org/10.64898/2026.… 1/7

Pretty cool. scholar.google.com/citations?user…

Can't wait to be able to check out this fun documentary staring my friends & colleagues @lukejharmon & @thesnailhunter_ (Christine Parent) "Snail Hunters (Official Trailer)" youtu.be/0qiAMNMxrJU?si… via @YouTube

The Biology Dept. @UMassBoston is searching for an Asst. Professor in "Microbial Ecology" (but 'microbial' is the operative word -- applicants studying evolution in microbial systems are also encouraged). For more info or to apply: employmentopportunities.umb.edu/boston/en-us/j…. Please share/RT.

Friends, colleagues, & other followers. I'm captaining a team in the Ride for Food '25 to raise money for Pete & Andy's Pantry in Rhode Island & no donation to our efforts is too small. To support us, please visit the team page here: ride.threesquaresne.org/team/658184. Thank you!!

For a more compact summary with all updates, check out my blog (blog.phytools.org), where you can also stay tuned for other new #phytools updates & features. 9/9

New simulator functions for absorbing bounded Brownian motion (sim.absorbing), Brownian motion with reflective bounds (sim.reflective), and multi-trend trended Brownian evolution (sim.multiTrend, blog.phytools.org/2025/07/a-mult…). 8/9

The #phytools R package has a new version on CRAN (cran.r-project.org/package=phytoo…) with various new models & updates, including.... 1/9
