ABSTRACT
Why does life evolve so much complexity? Evolutionary biologists do not agree answering this question; some of them even reject it on the charge of implying an “anthropocentric bias” (Gould, 1994). It is curious that neuroscientists and social scientists have found similar troubles dealing with the term complexity. In what grounds a nervous system, or a society, is more “complex” than another? Part of the problem with the term lies in that, very often, it is taken as a synonym of “advanced.”
