The broader implication extends beyond flowering plants. Many famous "rocks vs. clocks" debates may not require choosing sides. The challenge is finding better ways to let fossils and molecules speak to each other. Link to our latest: www.nature.com/articles/s41...

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.

🚨 Why can’t mammals regenerate limbs like frog tadpoles or salamanders? In our new paper in @science.org , we show that species-specific oxygen sensing acts as a gatekeeper for initiating limb regeneration 🐭🐸 🔗 www.science.org/doi/10.1126/... #EvoDevo

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 ...

Sponges are notoriously difficult to understand in evolutionary biology terms. I think this paper is a big step forward : www.science.org/doi/10.1126/...

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.
