FIGURE 3. Trees in different islands are connected through a sequence of trees of greater length. Higher plateaus represent shorter trees. The two highest plateaus correspond to the most-parsimonious trees of island-8 (left) and island-12 (right). Trees in these two islands differ by several branch rearrangements. They differ by five rearrangements through relatively long trees (lower path) or by more rearrangements through trees only one step longer than the most parsimonious (upper path).

This project started during my postdoc interview when I asked @ucsdcooperlab.bsky.social "jerboa tails seem longer. Have you looked into that?". It turns out the jerboa tail is approximately 1.5x longer than the mouse, normalized to body length, but with 3-4 *fewer* vertebrae than in mice.

Vertebral skeletal diversity in mammals is remarkable. How do the differences between vertebral size and shape develop and evolve? See how we tackled this question in our paper published in @natcomms.nature.com today!

A 126,000-year-old butt-drag just made fossil history.
A tiny rock hyrax scooted across the sand of ancient South Africa, and that moment was preserved in stone.

Even the smallest acts can echo through time.

incredible how older taxonomic literature in paleontology will describe geologically old, plesiomorphic (and potentially paraphyletic) taxa as "an important root-stock in evolution"

Welcome back to #fossilfriday

Here is the fresh water Dastilbe elongatus. This specimen comes from the Lower Cretaceous (Aptian-Albian) Santana Formation in Serra de Araipe, Brazil. The Santana Formation is well known for its exquisite preservation of pterosaurs fossils.

I'm on the BBC talking about (how we won't be) evolving into crabs 🧪🦀

Also features Matt Wills (my academic older brother) and Ned Suesat-Williams (of the crab museum!). Unfortunately they were in London and I on zoom, so there was no time to tell Ned to join here

It's also not "just another" extinction, it's the first from mainland Europe in centuries. CENTURIES.

And there will be others within our lifetime.

That's biodiversity loss.

Well, it's official. After our paper last year (onlinelibrary.wiley.com/doi/full/10....), the Slender-billed Curlew is officially declared Extinct today.

When sex chromosomes turnover, they can reset the rules of genomic conflict.

How can mitophagy be an effective quality control mechanism if mtDNA mutations reach high enough levels to cause disease?

This question led us into a dark path, full of concepts of evolutionary genetics, germline stem cell biology and mito-nuclear compatibility.

I've been wondering if I was going to see these revolutionary impacts of AI in my coding since seeing this video last year. To be sure, I still don't prompt AI with the assumption it can do things like this, because even for simpler tasks I often see fails. www.youtube.com/watch?v=M9YO...

I feel like this isn't common enough of a result to teach assuming that AI is right and often useful. I think we should be mindful and critical of everything as scientists, but extra critical of AI because it randomly can be incorrect. Teaching students to think critically is fundamental.

Y'all. I just got ChatGPT to do everything in R for this manuscript. I mean EVERYTHING. And it's all legit and reproducible. I'm shook.

How are we mentoring our trainees in statistics now? Who needs to learn coding in R line by line, and who doesn't?

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution.
