16. During preliminary analyses a set of 100 trees (covering all major uncertainties in the Stein et al. phylogeny) was generated randomly from the full tree set, with each tree pruned to match the ecological dataset using the function match.phylo.data in package picante21 in the R ...
tree (Supplementary Fig.1). Interestingly, we found that all Y-type sequences (those with Tyr at standard position 187, corresponding to position 170 in ancestral sequences) all form a relatively late branching clade in the phylogenetic tree (Supplementary Fig.1). By contrast, D-type sequence...
