Yes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

Excellent write up by @geosociety.bsky.social describing grant funded research by former post-doc Claudia Nunez-Penichet now @vt-invasivespecies.bsky.social on impending #marine #extinction threat www.geosociety.org/GSA/News/pr/... @kubiology.bsky.social @researchatku.bsky.social @kunhm.bsky.social

Hendricks and @bruceslieberman.bsky.social discussed the vital importance of museum collections for studying macroevolution in an article for the Paleobiology special issue celebrating the 50th anniversary of Punctuated Equilibria

Interesting a lot of recent theory-focused papers I've been reading about fossils don't acknowledge the vast amount of paleobiological literature on the subject(s) they're discussing. I'm happy folks are excited about fossils but also confused why folks seemingly aren't reading papers about fossils

Completely agree @daveyfwright.bsky.social !

I think you're right, likely not about competition. Can't say enough about what an awesome paper you folks have written!

You showed they're a great record of cultural #macroevolution @svalver.bsky.social ! Including my own growing up in the early 1980's 😉 . Loved the shout out to "Battlezone" - that was a challenging game. "Defender" or "Asteroid" examples?? 😃

New paper! The 1st publication from our NSF grant investigating local to global biodiversity patterns in marine invertebrates across the O-S boundary is out! Here, we describe a new crinoid from Anticosti Island & use Bayesian tip-dating approaches to quantify uncertainty in its stratigraphic age 🧪

For perspective, last year, 1.2 million unique visitors used our online educational materials...it's really a need of only 1 or 2 dollars per user, and it won't be an annual ask. Just one make or break 6 month period for an almost 100 year old research institution

Proud to say that I named the genus Bellacartwrightia,
in honor of @pcart.bsky.social , and also that the PRI is a great place and very much worth saving!
