The ToE works with populations, not individuals. Outside the impact an individual will have on the gene frequencies within a population, evolution doesn't 'care' about the individual. The success of the species as a whole is what evolution 'cares' about.
Therefore, the primary implication of evolution is that we should focus on the advancement of our species more so than ourselves. It is only through a weak understanding of evolution that one is able to hold the simple minded view that evolution promotes selfishness and survival of the fittest (individual).
Humans are no longer bound by the ToE as are other species. We now adapt our enviornment to suit us, we evolve culturally and technologically. Who cares if homosexuals exist because they made great babysitters back in our hunter/gatherer days? You live now, the ToE can suggest that maybe that's why we have homosexuals but it cannot force you to play that part. Why define yourself by what a theory says about how we came to be anyway? It may be more to do with the developmental enviornment than genes anyway!
