On the other hand, phytools does have a function - the somewhat
imprecisely named fastMRCA - which can find the MRCA of just a pair of
species much faster than getMRCA (however still slower than or only
about as fast as Joseph & Klaus's solutions).

Juan. findMRCA was written before getMRCA existed, but the latter was
faster so now it just calls getMRCA internally. All the best, Liam

Package phytools includes a function, findMRCA, that is supposed to work
very efficiently with large trees. you may wish to compare it with your
function.
