We may prefer to think of ourselves as fallen angels, but in reality we are rising apes.

We never stop investigating. We are never satisfied that we know enough to get by. Every question we answer leads on to another question. This has become the greatest survival trick of our species.

There are one hundred and ninety-three living species of monkeys and apes. One hundred and ninety-two of them are covered with hair. The exception is a naked ape self-named Homo sapiens. The zoologist now has to start making comparisons. Where else is nudity at a premium.

Life is like a very short visit to a toy shop between birth and death.

There is nothing biologically unusual about a homosexual act of pseudocopulation. Many species indulge in this, under a variety of circumstances.

The female covers her breasts, and then proceeds to redefine their shape with a brassiere. This sexual signaling device may be padded or inflatable, so that it not only reinstates the concealed shape, but also enlarges it, imitating in this way the breast swelling that occurs during sexual arousal.

No matter how old we become, we can still call them 'Holy Mother' and 'Father' and put a child-like trust in them.
