I love these things, though I am yet to see one that wasn't essentially pulled out of some racist's arse.

I would like to see one done with clades, where the total width represents the total energy available on earth. The width of clades would be calculated based on the irrevocable energy loss of that clade.

Sort of a history of who wastes the most energy, which would be a substitute for the "dominance" these things like to show.

The whole thing done with raw biomass would also be interesting.

Seems like a lot of work though. It would also be largely guesswork, I suppose.
