Yeah... But it's not fully true to use a tree shape. Languages have "horizontal gene transfer" as well (some call it "extensive contact" or whatever), and the branches come in and out more easily than what the prescriptive method shows.
Same for actual speciesation, on every level. On homo species, on any other species, even all the way down to the origin of eurcaryota, it's all a network. The tree was never the correct model, just a "neat" model.
