During the early twentieth century, scientists were keen to find some evidence that would prove the link between ‘early man and apes. In 1912 that evidence seemed to have been found while Dawson and Woodward were digging ‘on a site in Piltdown, in the south of England. As soon as they saw the jawbone and the skull, they decided that this ‘must be the evidence science needed. Woodward claimed that both bones belonged to a human being who had, lived about half a million years ago, during what is known as the Lower Pleistocene period. Most scientists accepted this opining until nearly forty years later when is was discovered that the Piltdown Man was a fake. Meanwhile Dawson who most people consider responsible for making the fake had died. The Piltdown Man hoax truly damaged science because by the time the hoax was discovered scientists had wasted nearly forty years believing a lie.
