Richard Dawkins Quotes

The late Christopher Evans, a psychologist and author, calculated that if the motor car had evolved as fast as the computer, and over the same time period, "Today you would be able to buy a Rolls-Royce for £35, it would do three million miles to the gallon, and it would deliver enough power to drive the QE2 And if you were interested in miniaturisation, you could place half a dozen of them on a pinhead."

The likelihood is that, in 100,000 years time, we shall either have reverted to wild barbarism, or else civilisation will have advanced beyond all recognition – into colonies in outer space, for instance. In either case, evolutionary extrapolations from present conditions are likely to be highly misleading.

It is an article of passionate faith among "politically correct" biologists and anthropologists that brain size has no connection with intelligence; that intelligence has nothing to do with genes; and that genes are probably nasty fascist things anyway.

It may be that brain hardware has co-evolved with the internal virtual worlds that it creates. This can be called hardware-software co-evolution.

Another force driving progressive evolution is the so-called "arms-race." Prey animals evolve faster running speeds because predators do. Consequently predators have to evolve even faster running speeds, and so on, in an escalating spiral. Such arms races probably account for the spectacularly advanced engineering of eyes, ears, brains, bat "radar" and all the other high-tech weaponry that animals display.

There is no general reason to expect evolution to be progressive – even in the weak, value-neutral sense. There will be times when increased size of some organ is favoured and other times when decreased size is favoured. Most of the time, average-sized individuals will be favoured in the population and both extremes will be penalised. During these times the population exhibits evolutionary stasis (i.e., no change) with respect to the factor being measured. If we had a complete fossil record and looked for trends in some particular dimension, such as leg length, we would expect to see periods of no change alternating with fitful continuations or reversals in direction – like a weathervane in changeable, gusty weather.

If we want to postulate a deity capable of engineering all the organized complexity in the world, either instantaneously or by guiding evolution, that deity must have been vastly complex in the first place. The creationist, whether a naive Bible-thumper or an educated bishop, simply postulates an already existing being of prodigious intelligence and complexity. If we are going to allow ourselves the luxury of postulating organized complexity without offering an explanation, we might as well make a job of it and simply postulate the existence of life as we know it!

There is one particular property of living things, however, that I want to single out as explicable only by Darwinian selection. This property is the one that has been the recurring topic of this book: adaptive complexity.

This not only misses the point, it is the precise antithesis of the point.

There are people in the world who desperately want not to have to believe in Darwinism.

The successful scientist and the raving crank are separated by the quality of their inspirations. But I suspect that this amounts, in practice, to a difference, not so much in ability to notice analogies as in ability to reject foolish analogies and pursue helpful ones.

There has been progress in design, but not progress in accomplishment.

It is generally characteristic of arms races, including human ones, that although all would be better off if none of them escalated, so long as one of them escalates none can afford not to.

Evolution normally does not come to a halt, but constantly ‘tracks’ the changing environment.

Contrary to earlier prejudices, there is nothing inherently progressive about evolution.
