Most teeth are for chewing or incising food, and thus I'd expect most teeth styles to be designed for diet. Canines aren't used for eating - they're used for killing. So I'd be surprised to learn that they evolved for diet only. I'm too lazy to do the research, but I'd be happy to be learn I'm wrong. A quick search turned up a somewhat relevant article about large canines in primates (not carnivorous): http://www.sciencedaily.com/releases/2008/06/080626145058.htm http://www.sciencedaily.com/releases/2008/06/080626145058.ht... It discusses whether they evolved the large canines for fighting or to impress females, but either way it wasn't related to diet.
