Demosponges were one of the first multicellular animals. Chemical fossils of distinctive steroids made by demosponges show that the group dates back to the Neoproterozoic era, significantly predating the Cambrian explosion. In PNAS: https://ow.ly/qNB750XaAmV

First post here to show a bit the work I did with Joëlle Barido-Sottani and Hélène Morlon on phylogenetic diversification models with heterogeneous rates in a Fossilized BD Framework
🦴:
www.biorxiv.org/content/10.1...
The paper is still under review but the method is already available in BEAST 2 !

The Fossilized Birth Death Process with heterogeneous diversification rates unravels the link between diversification and specialisation to a carnivorous diet in Nimravidae (Carnivoraformes)

Bayesian phylogenetic inference uses more and more complex diversification models as tree priors to test new macroevolutionary hypotheses. However, those models are usually developed in a neontologica...

Classic macroecological laws-long held as signatures of biological systems-also emerge in economic and geological systems. The real signal lies not in the static universal patterns, but in how those patterns shift with scale 🌐🧪 #scaling #macroecology journals.plos.org/plosone/arti...

Separating Macroecological Pattern and Process: Comparing Ecological, Economic, and Geological Systems

Theories of biodiversity rest on several macroecological patterns describing the relationship between species abundance and diversity. A central problem is that all theories make similar predictions f...

I am extremely happy to see that our review on fossil tip-dating is out in early view in Systematic Biology! A huge thanks to all the authors of this massive project (@heckeberg.bsky.social, @basantakhakurel.bsky.social, Gustavo Darlim, and @hoehna.bsky.social)! academic.oup.com/sysbio/advan...
