Where was the picture taken? This is essential info for species identification questions, and can narrow down the possibilities quite a bit.

comment Does evolution head to some optimum?
The question is unclear in many ways. First, you seem to be assuming that all species are evolving in the same fitness landscape, when all species (and populations) exist in their own fitness landscape. Second (assuming that a global optima really exists), why would this imply that all species but one should go extinct? Third, other species (the entire foodweb) constitutes "the environment" for a particular species, which means that the environment is never stable (since all species evolve).
