New paper out in Proceedings of the Royal Society B: we apply linguistic tools to sperm whale vowels. The result: sperm whale vowels do not just look like human vowels. They also behave like them. We found several parallels. Like in Latin, whales have short and long vowels.

Very nice and timely paper on phylogenomic model choice. Strong evidence that mixture models outperform homogeneous and partitioned approaches, with CAT-GTR showing robust performance across conditions. Highly relevant for difficult phylogenetic problems.

🚨 Why can’t mammals regenerate limbs like frog tadpoles or salamanders? In our new paper in

Species-specific oxygen sensing governs the initiation of vertebrate limb regeneration
Why mammals cannot regenerate limbs like amphibians do presents a long-standing puzzle in biology. To uncover the underlying differences, we compared amputation responses of embryonic mouse (Mus musculus) and Xenopus laevis tadpole limbs. Lowering ...

Apply now to join us in December for our workshop "Rethinking Cell Differentiation and Development: A Unicellular Perspective". This will be an intimate meeting (30 people total) and we hope will be a great place to discuss this topic.
add a skeleton here at some point

Did you know sponges are among the oldest animals on Earth? They're over half a billion years old! New research has helped to narrow down when they first evolved - and it could reveal more about the first ever animals! Find out more about these marine marvels 👇

Sponges are notoriously difficult to understand in evolutionary biology terms. I think this paper is a big step forward :

Independent origins of spicules reconcile paleontological and molecular evidence of sponge evolutionary history
Sponges have a cryptic Ediacaran history because ancestral sponges were soft-bodied and had low fossilization potential.
