In exile, at home 🇦🇷. Deep-time evolutionary biology, from genomes to fossils https://www.nmkphylo.com/
When I started my PhD ~10 years ago, only 2/5 echinoderm groups (the star-shaped sea stars and brittle stars) had genome-scale phylogenetic datasets. I am proud to say that the quest to complete the clade is now over doi.org/10.1098/rsos...
Phylogenomics of extant Crinoidea (Echinodermata) reveals extensive morphological homoplasies and a Permian origin
Abstract. Crinoids have Ordovician origins and are unique among living echinoderms in their attachment to the substrate. Most diversity is within Comatulid

Our latest paper, now how to conciliate apparently discrepant evolutionary rate patterns in squamates, but which may well apply to any study system with Stephanie Pierce and @7brumas.bsky.social #macroevolution academic.oup.com/sysbio/advan...
Evolutionary rate incongruences in squamates reveal contrasting patterns of evolutionary novelties and innovation
Abstract. Understanding the rate of phenotypic evolution can reveal fundamental aspects of organismal evolutionary trajectories. Hence, several studies hav

Inaccurate fossil placement does not compromise tip‐dated divergence times
Time-scaled phylogenies underpin the interrogation of evolutionary processes across deep timescales, as well as attempts to link these to Earth's history. By inferring the placement of fossils and us...

And finally have it in preprint: www.biorxiv.org/content/10.1... In it, we (@basantakhakurel.bsky.social, @brenenwynd.bsky.social, @peterjwagner3.bsky.social, and Christian Kammerer) took a look at estimating a phylogenetic tree of dicynodonts using both discrete and continuous characters.
Incorporating continuous characters in joint estimation of dicynodont phylogeny
Continuous characters have received comparatively little attention in Bayesian phylogenetic estima- tion. This is predominantly because they cannot be modeled by a standard phylogenetic Q-matrix appro...
