This is an interesting comparison from David Hillis.
The EGO diagram is a somewhat accurate illustration of one common perspective that places humans, and especially male humans, at the top of a hierarchy…although I don’t think most people would place whales so high. Cats and dogs would be somewhere just below Noble Man, but distant animals that are rarely seen in day-to-day life wouldn’t rank so highly.
The ECO diagram is a step in the right direction, but as Hillis points out, it’s still grossly vertebrate-centric. But then, the ecologists I know wouldn’t favor that diagram, either — they’d stock it with trees and grasses and insects and bacteria and fungi.
The EVO diagram is the best of them all, but has the problem that it’s also the least easily understood and the most complicated. But then if you reduced it to a smaller number of branches to make it more graphically appealing, you’d have to choose where to prune, and unfortunately for us humans, we wouldn’t be represented at all on a fair and simplified illustration of biodiversity.
