Three ways of looking at living entities

A Faccebook user, David Hillis, made this interesting three-part chart:

• The EGO section, inspired by the egoism of Homo sapiens, places a male human being at the summit, while more modest creatures (such as a human female) are located further down.

• The ECO section, inspired by an ecological outlook on various kinds of living creatures, includes the above-mentioned pair of human beings, together with various specimens of living creatures and plants that exist in the vicinity of humans.

• The EVO section, inspired by an evolutionary approach, is a slice of a tree trunk whose circular rings designate groups of living entities whose members are equally distant, timewise, from the start of life.
