"Science, and the rationalist movement in general, face a "sinister challenge" from leftwing thinkers who promote cultural relativism, according to evolutionary biologist Richard Dawkins.
He told a packed Hay Festival audience that although the threat from creationists and the religious right is well-documented, science is also under threat from the other end of the political spectrum: "I think we face an equal but much more sinister challenge from the left, in the shape of cultural relativism - the view that scientific truth is only one kind of truth and it is not to be especially privileged."
As an example, he cited Kennewick Man, the 9,000-year-old set of human remains found on the banks of the Columbia river in Washington State in 1996. The view of local native Americans that Kennewick Man was their ancestor, despite strong scientific evidence to the contrary, initially held sway, and they were able to put a stop to research."
