The second half of the 20th century was a golden age of molecular biology, and it was one of the golden ages of the history of science. Molecular biology was so successful and made such a powerful alliance with the medical scientists that the two together just flourished. And they continue to flourish.

But I feel music has a very important role in ritual activity, and that being able to join in musical activity, along with dancing, could have been necessary at a very early stage of human culture.

Secular humanists can sit around and talk about their love of humanity, but it doesn't stack up against a two-millennium-old funeral high mass.

Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.

The genes hold culture on a leash. The leash is very long, but inevitably values will be constrained in accordance with their effects on the human gene pool. The brain is a product of evolution. Human behavior-like the deepest capacities for emotional respone which drive and guide it-is the circuitous technique by which human genetic material has been and will be kept intact.

Real biologists who actually do the research will tell you that they almost never find a phenomenon, no matter how odd or irrelevant it looks when they first see it, that doesn't prove to serve a function. The outcome itself may be due to small accidents of evolution.
