This is the core insight of evolutionary theory – that natural selection is selective in an impersonal, non-cognitive way.Natural selection is not selection at all - selection implies intelligent determination - unless you want to go for a kind of pantheistic interpretation, at which point you are still beginning to point towards intelligent design
If you take a shovel full of gravel, and dump it into a colander or similar sieve, you will see selection happening before your eyes – small stones fall through, and big stones remain. The sieve doesn’t think, it doesn’t choose or refuse based on any intelligence it has. It’s an inanimate object, and the selection of big stones is just an artifact of its physical structure – its holes permit small stones through, and won’t let stones bigger than its holes.
That’s a very simple bit of pedagogy, but it demonstrates the process of selection as description of impersonal, physical processes. Natural selection is a much more complicated, dynamic sieve, and the criteria for what “stones pass through” are much more complex than the simple, regular lattice of the colander under your sink, but the principle is the same - natural, impersonal processes doing their thing.
