Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.

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.

It is a shock to us in the twentieth century to discover, from observations science has made, that the fundamental mechanisms of life cannot be ascribed to natural selection, and therefore were designed. But we must deal with our shock as best we can and go on.

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