Also from Doyle’s ebook, a brief introduction to ‘biological information’:
"The Biology of Free Will
Perhaps physics now puts no limits on human freedom, but what about biology? Each of us gets a significant amount of genetic information from our parents, which at least predisposes us to certain behaviors that have evolved to improve our reproductive success, sexual behavior, for example.
Are we completely “determined” by a combination of our biological nature and the social nurture of our environmental conditioning? Is biology itself all a causal process that is simply unfolding from a distant past that contained all the information about the one possible biological future?
Information biology says no. While the stability of biological systems is extraordinary, and while their error-free performance of vital functions over many-year lifetimes is astonishing, their dependence on randomness is clear. Biological laws, like physical laws, are only adequately determined, statistical laws.
At the atomic and molecular level, biological processes are stochastic, depending on thermal and quantal noise to deliver the “just-in-time” parts needed by assembly lines for the basic structural elements of life, such as the amino acids needed by the ribosome factories to assemble proteins.
So our question is how the typical structures of the brain have evolved to deal with microscopic, atomic level, noise. Do they simply ignore it because they are adequately determined large objects, or might they have remained sensitive to the noise because it provides some benefits?
We can expect that if quantum noise, or even ordinary thermal noise, offered benefits that contribute to reproductive success, there would have been evolutionary pressure to take advantage of the noise.
Many biologists argue that quantum-level processes are just too small to be important, too small for the relatively macroscopic biological apparatus to even notice. But consider this evidence to the contrary." . . . see the chapter titled "The Biology of Free Will," following the chapter on the physics of free will.
