CIPRES is shutting down at the end of June: www.phylo.org .

It's been such a good resource for the phylogenetics community. Thanks to #NSF and Simons for funding it and for all the people who have worked to grow and sustain this for so long.

So you are using IQ-TREE to estimate a tree for "deep time" phylogenetics using amino acid alignments. There is a lot of confusion about how to test model fit. Here are some suggestions.

The table shows the items we used as part of our scientific activity for this outreach event at UCL Illuminated: various skull casts from different species and an activity that uses dinosaur species for familiarising with landmarking and the usage of morphology for the study of evolution.

Nath & Sandy ready for talking about the usage of morphology and DNA for the study of evolution during UCL Illuminated as part of their outreach scientific activity -- we were there from 17.30h to 22.00h!

Adaptive radiation of pelagiarian fishes at the K/Pg boundary led to rapid diversification of mandible morphology Abstract. Mandibles represent a key evolutionary innovation that has enabled jawed vertebrates to adapt and diversify in response to a range of food source

New paper! Here we look at shape evolution of the mandible in Pelagiaria, a group of open-ocean fishes that includes tuna and mackerel. We find that shape disparity accumulated rapidly at the origin of the clade at around the K/Pg boundary... academic.oup.com/evlett/advan...

Really pleased to be part of this project which shows that aerobic bacteria arose in the Archaean, long before the GOE - after which aerobes proliferated through HGT. Fun @bristolpalaeo.bsky.social collab including @tweethinking.bsky.social @sabifo4.bsky.social @emoody.bsky.social Davide Pisani
