During a discussion with a friend, I was asked a question about evolution and neither of us had an answer. Maybe someone here could explain.
If evolution is a naturally occurring event, why don’t some DNA strands rotate in the opposite direction?

Darned if I can cite the source off the top of my head, but it had something to do with circularly polarized cosmic rays coupling more efficiently to one direction of a helix and preferentially disrupting its function?

The Left Hand of the Electron, by Isaac Asimov, chapter 5, The Asymmetry of Life.
Beta particles when slowed down by passing through water emit left-circularly polarized gamma rays. That means D-amino acids are less easily formed and more easily destroyed.
