Dear colleagues,
I have a large species-level phylogeny in which the tip labels are
indicated as "Genus_species". All genera are monophyletic.
I have two things I'm struggling with:
(1) I'd like to drop all but one of the tips in each genus (i.e. to
generate a genus-level phylogeny). Given that all genera are
monophyletic, it shouldn't matter which species I pick.
(2) I'd like to establish an era (e.g. 25 Mya) and leave only one
representative of the clades there were present at that point in time.
Given that I actually have a post-burnin set of trees, once I figure out
how to do the steps above I could (hopefully) do that for all trees.
thanks so much for your help.
Susan.
