Reflecting on biology and quantum mechanics in my last post made me notice that they are based on a common principle: regularity and reliability arising out of fundamental randomness at bottom.
According to quantum mechanics, subatomic particles behave in unpredictable ways (even in ways that seem downright illogical); and the regularity we observe in the world arises because when you have a very large number of particles, the individual random behaviors cancel each other out and result in a very stable, predictable system.
Biology (here I am thinking mostly of biochemistry) operates on the same principle. It all works in terms of concentrations and averages; it’s never about deterministically making sure one particular protein does a particular job, but of adjusting concentrations so that on average “enough” of a particular reaction will occur. And at a larger scale, the way living organisms utilize random change in their genomes to adapt to an environment is absolutely incredible.
This is not enough to establish that there is one Mind behind both the laws of physics and biological life, but to me it’s a hint that there is.
