Biology

The main place I discuss applications to biology is on pages 383–429 of Chapter 8, where I consider first general questions about biology and evolution, and then more specific issues about growth and pattern in biological organisms. I consider visual and auditory perception on pages 577–588, and the operation of brains on pages 620–631. I also discuss the definition of life on pages 823 and 1178, as well as mentioning protein folding and structure on pages 1003 and 1184.
