The fact that species X also has feature 3 tells us nothing about its
evolutionary history. In both cases, we need context--comparison with the
distribution of character states in other taxa, the distribution of taxa in
other areas. And I would venture (though John might disagree) that neither
phylogeny nor biogeography is satisfactory in the absence of the other. (As
a phylogeneticist, I am persuaded that phylogeny is more important to
biogeography that the reverse.)
