Life in the Universe Accident Chance or Preconceived


Richard Dawkins
It's no accident that we see stars in the sky, says famed Oxford biologist Richard Dawkins: they are a vital part of any universe capable of generating us. But, as Dawkins emphasizes, that does not mean that stars exists in order to make us."It is just that without stars there would be no atoms heavier than lithium in the periodic table," Dawkins wrote in The Ancestors Tale -- A Pilgrimage to the Dawn of Evolution, "and a chemistry of only three elements is too impoverished to support life. Seeing is the kind of activity that can go on only in the kind of universe where what you see is stars."

"It's an astonishing stroke of luck that we are here." That was Dawkins' evolutionary message at a recent speech to a packed auditorium at the Christchurch, New Zealand. "Every animal owes its existence to an astonishing list of contingencies that might not have happened. With so much chance and luck it might be thought that evolution itself is a process of pure chance, but nothing could be further from the truth."


It was predictable, for example, that eyes and ears would develop in different species, and they had done so independently several times over, Dawkins said. "Natural selection is the great engine of the predictable side of life, but it cannot start without certain prerequisites."


Dawkins said it was his gut feeling that there has been another stroke of luck that would have developed life elsewhere in the Universe.


"There are billions and billions of planets out there, so there could be millions of planets that have life on them, but the origin of life could still be a staggeringly good stroke of luck," he said.


To Richard Dawkins believing in God is like believing in a teapot orbiting Mars. Dawkins said that a sense of gratitude had developed as an essential part of human societies. This meant humans had an overwhelming desire to give thanks, even when there was no-one to give thanks to and this, in part, had given rise to religion.


Dawkins sees himself as a "religious non-believer" who's career has revolved around Darwin's view that all was 'produced by laws acting around us' described so powerfully by Darwin in the Origin of the Species:


"Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving -- namely, the production of the higher animals -- directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."
