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

@NHMdinolab Yes indeed. And that was partly the inspiration for this paper - particularly answering the question: do different coding strategies give different results? I would have thought so, but actually model and outgroups seem to be more important.

@evopalaeo Looks a lot like the conclusions we reached in Campione et al. (2020)!

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. biorxiv.org/content/10.110…

@sahinmy @nrken19 If you are referring to mammalian hair, almost certainly the former. If you are talking about pterosaur fuzz, our study suggests that it independently evolved from scales, although the minority of models support a single origin of feathers/fuzz, followed by multiple losses.

@evopalaeo @nrken19 Did hair and feathers evolve separately from scales or do hair and feathers have a common ancestor closer than scales?

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!
