Phylogenetics, bryophytes and fossils 🌿🪨... and a bit of music and rock climbing 🧗♂️🎸
Excited to share our latest paper — we describe Corsiniopsis kurtzii, a fertile marchantioid fossil from Argentina that sheds light on the evolution of xerophytic lineages and their unique reproductive traits. #FossilFriday #bryophytes

Great article by @philipcball.bsky.social about recent work on LUCA, quoting Tim Lenton and UIUC alum Rika Anderson. Glad to see mention of early horizontal gene transfer as a driver of evolution.

Luca is the progenitor of all life on Earth. But its genesis has implications far beyond our planet
New research into the single-celled organism is providing clues about what the early planet looked like – and raising the prospect that we may not be alone in the universe

I was checking some "old" files and came across this beautiful Devonian landscape by Carmen F. Ulivarri (ig: @ilustra.botanica.uel).
It showcases a hypothetical "ancestral" #bryophyte – a tiny Blasia-like liverwort, that had pretty much the same features of modern simple thalloid liverworts. 👉

Our new paper on the #phylogeny of Osmundales is out. We reviewed the phylogeny of the group by taking into account character dependence and found that most of the recognised groups are hardly when dependencies are ignored. Check it out

New sabertooth paper!
Dr Tahlia Pollock & her team of #evobio wizards look at how optimality landscapes may have driven the evolution of saber teeth. Also, they underscore that there aren't just 1 or 2 saber-shapes; nature is varied!

Functional optimality underpins the repeated evolution of the extreme “saber-tooth” morphology
Saber teeth are a classic example of convergence, having evolved repeatedly throughout mammalian history. Using 3D morphometrics, biomechanical testing, and a Pareto optimality analysis, Pollock et al. identify functional optimality as a key driver underpinning the repeated evolution of extreme saber-tooth morphologies.
