Natural Selection never made it come to pass, as a habit of nature, that an unsupported stone should move downwards rather than upwards. It applies to no part of inorganic nature, and is very limited even in the phenomena of organic life.

Natural selection is anything but random.

Natural selection eliminates and maybe maintains, but it doesn't create.

We have stopped natural selection from purifying the species because deep in our heart of hearts, we are all terrified that we won't make the cut.

Perhaps the most legitimately dispiriting thing about reciprocal altruism is that it is a misnomer. Whereas with kin selection the "goal" of our genes is to actually help another organism, with reciprocal altruism the goal is that the organism be left under the impression that we've helped; the impression alone is enough to bring the reciprocation.

Ideas percolate. Through natural selection, the best ones survive.
