“This touches on the issue of how vegans should handle the caveman argument. Many of us are tempted to strain credulity and torture the evidence to ‘prove’ humans are ‘naturally’ vegan. This is a trap, and one into which carnists (especially paleo-dieters) would love us to fall; the evidence isn’t on our side. There’s no doubt that hominids ate meat.... The argument for veganism has always been primarily ethical, and ought to remain that way. It’s based on a concern for the future, not an obsession about the past.”
