7 Richard Dawkins Quotes on Time

Richard Dawkins quotes on time

34. 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.

48. The river of my title is a river of DNA, and it flows through time, not space. It is a river of information, not a river of bones and tissues.

55. ... it seems that it would take less than half a million years to evolve a good camera eye ... It's no wonder 'the' eye has evolved at least 40 times independently around the animal kingdom ... It is a geological blink.

92. Molecular evidence suggests that our common ancestor with chimpanzees lived, in Africa, between five and seven million years ago, say half a million generations ago. This is not long by evolutionary standards ... in your left hand you hold the right hand of your mother. In turn she holds the hand of her mother, your grandmother. Your grandmother holds her mother's hand, and so on ... How far do we have to go until we reach our common ancestor with the chimpanzees? It is a surprisingly short way. Allowing one yard per person, we arrive at the ancestor we share with chimpanzees in under 300 miles.

105. But even with these conservative assumptions, the time taken to evolve a fish eye from flat skin was minuscule: fewer than 400,000 generations. For the kinds of small animals we are talking about, we can assume one generation per year, so it seems that it would take less than half a million years to evolve a good camera eye.

109. The shape of a constellation, moreover, is ephemeral. A million years ago our Homo erectus ancestors gazed out nightly at a set of very different constellations. A million years hence, our descendants will see yet other shapes in the sky, and their astrologer (if our species has not grown up and sent them packing long since) will be fabricating their oracles on the basis of a different zodiac.

145. If somebody believes that the world is only (...) a few thousand years old, when the true age of the Earth is of the order of a few billion years old, that means they are out by a factor of... a million. Which is not a trivial error.
