Natural selection certainly operates. It explains how bacteria will gain antibiotic resistance; it will explain how insects get insecticide resistance, but it doesn't explain how you get bacteria or insects in the first place.

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.

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

But the very fact that Darwinism is true makes it even more important for us to fight against the naturally selfish and exploitative tendencies of nature.We can do it.Probably no other species of animal or plant can. We can do it because our brains (admittedly given to us by natural selection for reasons pf short-term Darwinian gain) are big enough to see into the future and plot long-term consequences.
