I've seen no evidence of a god, so I'm not going to think about one. Being raised nonreligious made you free. You could look at the evidence. Whether… - James Watson

Our low gene count by no means invalidates a reductionist approach to biological systems, nor does it justify any logical inference that we are not determined by our genes. A fertilized egg containing a chimp genome still inevitably produces a chimp, while a fertilized egg containing a human genome produces a human. No amount of exposure to classical music or violence on TV could make it otherwise. Yes, we have a long way to go in developing our understanding of just how the information in those two remarkably similar genomes is applied to the task of producing two apparently very different organisms, but the fact remains that the greatest part of what each individual organism will be is programmed ineluctably into its every cell, in the genome.

Watson: Our society just hasn't faced up to this problem. In a primitive society, if you saw that a baby was deformed, you would abandon it on a hillside. Today this isn't permissible, and with our medicine getting better and better in the sense of being able to keep sick people alive longer, we are going to produce more people living wretched lives. I don't know how you get a society to change on such a basic issue; infanticide isn't regarded lightly by anyone. Fortunately, now through such techniques as amniocentesis, parents can often learn in advance whether their child will be normal and healthy or hopelessly deformed. They then can choose either to have the child or opt for a therapeutic abortion. But the cruel fact remains that because of the present limits of such detection methods, most birth defects are not discovered until birth. If the child were not declared alive until three days after birth, then all parents could be allowed the choice that only a few are given under the present system. The doctor could allow the child to die if the parents so chose and save a lot of misery and suffering. I believe this view is the only rational, compassionate attitude to have.

The finding that there is a substantial genetic component to our behavior should not surprise us; indeed, it would be far more surprising if this were not the case. We are products of evolution: among our ancestors, natural selection indubitably exerted a strong influence over all traits that have figured in our survival.
