Our reduced canines are visible examples of "human nature" as cooperative- people can wax poetic all they want in support of violent individualism, but we exist right now because we evolved to survive & thrive as a group, cooperativly. And thats not only true of US. Its true of many social animals.

Many things are natural and we can have debates all day about the existence and benefit of aggression but the core of human nature is that we survive together and we die alone. We are not solitary primates, we need each other and the fallacy of competition these guys are chasing after is killing us

seems like it!!! :D
