[QUOTE="Gez, post: 1867949, member: 1328"] You can make a biological graph, but it won't be a tree. (A tree is a special kind of graph where there is only one path from the source (root) to any particular end (leaf).) For example, take a Gryphon. It is descended from both birds (giant, or at least large, eagles) and lions. Up to (or down to, if you prefer) eagles and lions, you have a biological tree. If you go toward the root, you'll see both converge toward a same origin, since they're both vertebrates. But, upon arriving at Gryphon, you have two branches of the tree that are merging into one! And then, at Hippogriff, a third branch (horse) merges in, too! But it's not all, since you have the Sphinxes, which, biologically, are close to the griffons (same lion body, same eagle wings). But the sphinxes have a head that's either human (andro-, gyno-), ovine (crio-), or avian --specifically, falcon-- (hieraco-). So, sphinxes are descended from gryphons (hence lions and eagles), humans, rams, and falcons. And then, you have the Lammasu, which could probably be put in the Sphinx family. But the Shedu, which are said to be cousins of the Lammasu, have a bovine body! [/QUOTE]
