Live Long to Prosper

I've been delving into evolutionary psychology (just look at the books I've been reading recently). I plan on heading over to the library tomorrow to check out yet another book on the subject. I hope the next book does more than cast everything as part of the arms race to get one up on our competition to sire the next generation. Sure there may be a few factors on the margins that do have that role, but what was common to those that managed to reach reproductive age that gave them an advantage? Where are the investigations into this question? Besides, the evolutionary refrain that all things are directed towards attracting a mate gets a little tiresome after awhile. It feels flimsy, insubstantial, and incomplete. The fact that we managed to live long enough to even reach reproductive age seems like a factor that should take a more central role in the development of very interesting and compelling ideas. The evolutionary framework provides a perspective on human actions, which are guided by instinct far more often than reason, that tells us more about who we are than other theoretical constructs of human behavior. To reduce everything to a drive to get laid belittles our biological heritage.
