Richard Dawkins says the world would be changed by anything that blurs the boundaries between humans and chimps. Like, the discovery of a missing ancestor, or a lab-based chimera. Because the issue of human rights would have to be re-thought from scratch. The Guardian has helpfully published this as ‘Richard Dawkins: how would you feel about a half-human half-chimp hybrid?’. Which I’m sure does wonders for the public image of scientists.
