Sure, it’s pretty common, and it never ceases to amaze me. But what I find particularly interesting about treehood is that it’s just so unexpected: I would never have expected that palm trees, aloes and gum trees (to take two random examples) not only both independently evolved from unrelated nontrees, but also evolved completely different ways of structuring themselves to do so, to end up with practically indistinguishable results. (Yes, I know they can be distinguished, but it takes some practice and still isn’t obvious.)
