Isn't that like saying "because genetics" or "because chemistry" or "because biology"? It doesn't really answer the question that the article is asking.

Yeah, and also the brain's dopamine levels are not homogeneous. Your dopamine can be low in one part of the brain and high in another. Also, dopamine receptors can have low/high count in different areas.

That's a bit like saying that Newton's gravity law doesn't explain why the planets move. It's true that "because genetics" doesn't tell you why it happens, but it might be the deepest answer possible. We are servants to our genes.

  >We are servants to our genes If so then how do you explain phenomena like suicide and celibacy?

    It is commonly assumed that evolution tries to maximize its outcome using a greedy algorithm. In fact it seems to be a random walk across all possibilities, with unviable branches dying out over time. Suicide may also be a second order effect of other factors. For example, suicide usually has a cultural basis: you feel some sort of shame, or maybe you think your future outcomes aren't good culturally. But that means you care about society. Therefore suicide may be an indication that we have evolved to optimize society rather than ourselves. If we didn't care about society, perhaps there would be less suicides, but it would also make humans less dominant.

      >Suicide usually has a cultural basis Yes -- hence copycat suicides. But cultural, not genetic. Ideas, not genes.

        I would argue that culture is incorporated into our genes. For example, humans show signs of domestication, just like certain animals. But domestication is another name for cultural genetics.

        Wouldn't it be accurate to say apoptosis is incorporated into our genes?

    If evolution is the changing of statistical distributions of genes within a population, then reproduction isn't the only aspect of life that is germane. That's because your children are just one example of people whose genes correlate with yours. Practically anything you do affects other people in society who have some genes in common and therefore impacts the future distribution of genes. This is why being menopausal, infertile, homosexual, celibate, or whatever does not place you outside of or make you irrelevant to evolution.

Well I didn't meant it to be in negative way. Sorry its answering the `how` part of question not `why`, but whatever be the reason of `why`, the final thing that brain finds pleasurable is because of dopamine. For example, lets say a person like classical music but might dislike rap or metal. This is because his brain is accustomed to classical music and the more he listens to it, the more dopamine is released. However, in case of other genres, brain is not accustomed to it and thus the pleasure hormone might not work.
