It does if you view "complexity" as a whole-istic entity. Complexity can
be defined a multitide of ways, which, as is the case with
"evolutionary-direction", is essentially meaningless.
You just put ONE criterium as the definition for "complexity": our large
brains. That has an ominous tone of the Old Testament view of man as the
"apex" of what life is all about. Fine. I choose a more technical
definition: one that embraces adaptation, geological longevity, species
diversity, structural apomorphies, how many niches a species can fill, etc.

Have you ever looked at the number of chemical steps there are during the
process of photosynthesis?
