In theory, phylogenetic trees can be constructed to include every organism from single cells up to modern multicellular organisms, but in practice, such a tree would contain so much information and have so many branches that it would be unreadable.

These people tried. It's a PDF, so you can zoom in and in and in--the fuzz you start to see around the edge after a few zooms is actually the names of species.

Wow, that phylogenetic tree is truly amazing, although it looks like it includes only mammals. It’s also a little much for my poor computer to handle. :(
