quote:
DNA on the other hand is very much less abstract. The code itself is entirely physical, and more than that the entire organism is created from this code. The organism isn't an environment for the code to run it, it is the result of "running" the code.
It is also the case that the majority of human brain development (the development of neural connections specifically) is not coded by DNA directly.
It seems that our DNA sets up several evolution-like stages of brain development in which it tells the body to make lots and lots of neural connections but it is the environment that determines which ones survive. The rest die off.
DNA and the environment work hand in hand to create our brains, and there seems to be no supernatural intervention.
