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.

Thought I would share this famous analogy from Felsentein’s book I just re-stumbled on. Just in case you’re bug in a box and missed it 😜

I’m looking for a post doc (up to five years) interested in phylogenetics and earth systems - please spread the word!

Hit me up if you'd like to apply to a Data-driven postdoc fellowship with me in Sweden. 2 year salary, excellent community. Deadline March 31. I have a project idea on reference bias vs pangenome, but keen on hearing ideas. Please share broadly. www.scilifelab.se/data-driven/...

I am looking for a postdoc to develop high-performance algorithms in computational genomics. Email or DM me if interested. For more information, see hlilab.github.io/vacancies. RTs appreciated!

We’re so used to conflicting phylogenetic results that we tend to shrug shoulders. Nice to see how @caseywdunn.bsky.social digs into one such conflict, finds the issue, and resolves it. Bravo!

What are the good free LIMS these days used by molecular labs? We mainly need to link specimen and sample information.

We recently published a follow up in a new article published in @genomebiolevol.bsky.social about the hemoglobin gene cluster deletions in the icefish ancestor. We show that each deletion involve different mechanisms and that transposons fueled these deletions! 🐟🧪🌎🧊🇦🇶 academic.oup.com/gbe/article/...

Very excited to share that our latest paper is out in Science! We show that the type specimen of Nanotyrannus—an isolated skull—is fully grown, showing that it is not a juvenile Tyrannosaurus rex but a distinct species (1/12) www.science.org/doi/10.1126/...

Come tell us about your cool new evolutionary work on Antartic (and/or sub-Antarctic) fishes! It doesn't have to be notothenioids, we love all the fishes (and Evolution)!! 🧪🌎🐟🧊🇦🇶 @scar-antarctic.bsky.social @usscar-antarctic.bsky.social

A unique feature of gars is those distinctive armor-like scales! Unlike a typical fish’s overlapping scales, gars have interlocking “ganoid” scales that are made up of a material similar to the enamel on our teeth. The name “Lepisosteus” even means “bony scale” 🦴 #25DaysofFishmas

Popgen folks, Jiseon, Nate, and Andy, along with Yuxin Ning and Franz Baumdicker, just released a really cool new method for simulation based inference (think ABC) using normalizing flows. It seems to work really well! full joint posteriors ftw! www.biorxiv.org/content/10.6...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

I'm hiring a postdoc... By combining samples that are more than a million years old with the short generation time of small rodents, we hope to gain a unique window into evolution unfolding across millions of generations!

While trying to see if two populations of the Antarctic longfin icedevil fish Aethotaxis mitopteryx were genetically differentiated, we uncovered a clear sex signal demonstrating that in this rarely encountered species males are the heterogametic sex! 🧪🐟🌎🐧🧊🧬 onlinelibrary.wiley.com/doi/10.1002/...
