Well no, 2 randomly selected trees for the same species are quite likely to have a recent common ancestor (contrasted with, say, a tree and fish) because they're the same species. I was under the mistaken impression that "tree" was a phylogenetic thing. Like, they're all descended from some distant great-grandmother-tree or something. The surprising thing was that this is not the case, and many separate species have all discovered how to tree individually.
