This is behind the Buddhist prayer of thanks "for this precious human body" — only in a human body can enlightenment be attained. Not gods, not animals, not demons, not angels: only with this human body can I awaken to the empty Ground that is equally present in all other sentient beings. This, too, is Aurobindo's and Murphy's emphasis on The Future of the Body, the precious human body. And that human body is, among many other things, the product of evolution.
