God or evolution?

Evolution? Why is this an isolated case? Why hasn't any of the known primates evolved into some kind of Australopithecus?

Why immediately primates? For many centuries, all sorts of animals have been constantly evolving. At least, I believe this more than I believe that there is a male being in the heavens, thinking about the well-being of every person. I also really enjoy reading about how people will burn in hell for gluttony, lust, and something else (that is, we will all be there), while God is merciful, hallelujah!
