Have you ever seen the mathematics on this? When so much is being selected "at the same time" it seems like most of the time it would never get selected in the wash. After all, selection works on an individual organism, and it's binary: either the organism survives, reproduces and passes on its genes, or not (we are not talking about DNA swapping between microorganisms here). This binary signal is supposed to be the "vote" for whether a particular combination of genes is more fit or not. But you can't just say "it's all possible given a really long time", you'd have to actually quantify what the chances are of say, the mechanism a single vote selecting simultaneously 1000 different traits, would increase the prevalence of all the "beneficial" traits. Do you have enough resolution to decide e.g. whether the bone density, color of skin or the length of legs was the factor that led to survival?
I am especially not sure why it would select the traits -- like a colorectal angle -- that would make an individual simply more comfortable rather than make a tangible difference to survival.
If we took the predictions of evolutionary theory seriously, then their contrapositive seriously too. In particular why would gay people exist if genetically homosexuality confers a much lower genetic fitness? Why do we say homosexuality is primarily genetic if evolution is true?
