I suspect, should the human race disappear from the cosmos, it will be because our tool making ability (read the ability to make war) grew faster than our intelligence or our morality. Like everything else weapons that can kill millions become ever more available to more and more people. Eventually someone (and yes, I suspect it will be some brand of religious fanatic) will get their hands on a truly deadly weapon, probably biological, and ignite an conflict that pushes civilization to the brink of collapse.
Even if we survive the current bought of madness, "the human race" is a temporary resident in the cosmos. Evolution hasn't stopped, our species is not the end of some predetermined road. Should we ever manage to take to space and spread, it will not be many generations before the species, adapting to radically different environments to the ones we have known so far, branches along multiple adaptive paths.
