Quotes

 * Darwinian evolution is most unlikely to get even one polypeptide [chain of essential life substances] right, let alone the thousands on which living cells depend for survival. This situation is well known to geneticists and yet nobody seems to blow the whistle decisively on the theory.
 * Fred Hoyle and Chandra Wickramasinghe in their book Evolution From Space.
 * Sir Fred Hoyle and Chandra Wickramasinghe assert that the chances of life’s springing from some ancient random mixing of chemicals are so “outrageously small” as to be absurd “even if the whole universe consisted of organic soup.”
