How were they altered you ask? Darwin's masterpiece will include a 50-page introduction that slams evolution and paints Darwin as both racist and misogynistic and explicitly highlights "Adolph Hitler's undeniable connection to the theory." (this awesome YouTube video addresses many of Cameron's ridiculous points, one by one)
Thankfully, evolutionary biologist Richard Dawkins answers back with a book of his own:
In "The Greatest Show on Earth", Richard Dawkins takes on creationists, including followers of 'Intelligent Design' and all those who question the fact of evolution through natural selection. Like a detective arriving on the scene of a crime, he sifts through fascinating layers of scientific facts and disciplines to build a cast-iron case: from the living examples of natural selection in birds and insects; the 'time clocks' of trees and radioactive dating that calibrate a timescale for evolution; the fossil record and the traces of our earliest ancestors; to confirmation from molecular biology and genetics. All of this, and much more, bears witness to the truth of evolution. "The Greatest Show on Earth" comes at a critical time: systematic opposition to the fact of evolution is now flourishing as never before, especially in America. In Britain and elsewhere in the world, teachers witness insidious attempts to undermine the status of science in their classrooms. Richard Dawkins provides unequivocal evidence that boldly and comprehensively rebuts such nonsense.
