Re: Freewill
It's not all genes. Plenty of it is environment. And "genes" don't really exist without environment. Genes are sequences of nitrogenous bases in an alternating sugar-phosphate chain that makes up a long molecule called a chromosome. Physical damage to the chromosome can change the genes. As can errors when the chromosome is splitting in two or when the gene is being turned into a protein. And the proteins created from the gene can still be damaged and affected by the environment. Which proteins are created is often a matter of environmental factors. Hell, when all of these proteins, interacting in the appropriate ways, result in the brain itself, that brain is highly subject to environmental factors. And then the life of the individual person - the organism that brain is attached to - can proceed in many different ways depending on the environment. And I've skipped a few steps.
DNA is just a molecule, not some "magic map" of the future.
