This is exactly what findMRCA in phytools does, but I wrote it a while
ago so I'm not sure how fast it is....

Hi All,
The 'mrca' function in Ape provides a method for finding the common
ancestor of a pair of taxa. What I would like have not found is a function
where you can pass a (long) list of tips from a phylogeny and find the node
which represents the common ancestor to all these tips.
Does such a function exist? Or could the 'mrca' function be expanded to
loop over all the taxa within a list a somehow boil down to what is the
common ancestor that way?
Thanks,
Nick
