YOU CANNA CHANGE THE LAWS OF BIOLOGY: What I got out of this neat little article (concerning a panel divided between physicists working on time, and other researchers taking biological approaches to investigating time) is that while physicists continue to debate the exact nature of time, and what direction it goes in, or if it has a direction, biologists don't even question that time goes one way. Evolution doesn't work without time's arrow! And evolution "has also produced brains that seem extremely adept at navigating a world in which time's arrow is real."
