  3. Charles Darwin 1809 - 1882 Attenborough on Darwin “……can we doubt (remembering that many more individuals are born than can possibly survive) that individuals having any advantage, however slight, over others, would have the best chance of surviving and procreating their kind? On the other hand, we may feel sure that any variation in the lease injurious would be rigidly destroyed. This preservation of favourable variations and the rejection of injurious variations, I call NATURAL SELECTION.” – On the Origin of Species

  8. Belief in evolution Untouched by the hand of God How people in various countries view the theory of evolution Feb 5th 2009 IT IS 150 years since the publication of Charles Darwin's theory of evolution, which suggested that all living things are related and that everything is ultimately descended from a single common ancestor. This has troubled many, including Darwin himself, as it subverted ideas of divine intervention. It is not surprising that the countries least accepting of evolution today tend to be the most devout. In the most recent international survey available, only Turkey is less accepting of the theory than America. Iceland and Denmark are Darwin's most ardent adherents. Indeed America has become only slightly more accepting of Darwin's theory in recent years. In 2008 14% of people polled by Gallup agreed that “man evolved over millions of years”, up from 9% in 1982 Ross and Phoebe
