Brown Nugget has just finished 20,925,000 ancestral state estimations. š«” I realise that without context, this makes no sense.

When did feathers evolve? Are bird feathers homologous with pterosaur tufts? Check out our new preprint, lead by the fantastic Pierre Cockx. We use different models, outgroups and coding strategies to clarify feather evolution.

Happy to share the preprint from part of my PhD thesis. The work behind this paper was massive and I couldn't have done it without the expertise and effort of my colleagues, collaborators, supervisors and friends!.

This is very much a work in progress and I'm keen to get feedback. Let me know what you think!.

There is also a function for computing tree to tree distances in parallel using the foreach package. This will allow you to visualise tree spaces with large numbers of trees!

You can also simulate a tree under the assumption of competitive exclusion, which produces topologies quite unlike those of birth-death trees. Optionally you can also simulate a mass extinction.

You can automatically extract tip priors from phylogenetic data, which can be used as inputs in a bunch of ancestral state estimation packages (e.g. phytools, corHMM, castor).

This function will also spit out the calibration as a MrBayes command, reporting the minimum age, mean age and standard deviation (e.g. offsetgamma(457.5, 496.2825, 38.7825);).

You can formulate fossil calibrations using exponential and gamma distributions. This is helpful for specifying how representative the oldest fossil is of the maximum clade age.
