The question should be first, "will humans evolve?" That's impossible to say. We're not likely to have any genetic bottlenecks in the forseeable future, barring near-extinction events, societal collapses and subsequent isolations, or new colonizations of areas. Right now, the effective genetic pool you and I share extends to literally billions of people, and there are few genetic links to particular success in survival and breeding. If we do create future bottlenecks, though, some sort of evolution may occur.

The next question is, "will humans evolve in a way preventing war?" That's unlikely. War is, in my view, the near-unavoidable result of societies existing in a system in which at least one resource of some sort is limited. Humans, being highly social (and with societies having enormous advantages) are unlikely to evolve in such a way that societies no longer exist.

However, I think it's quite possible that war is ended. Such would require one of three things.

1. Humanity is merged into one effective society, that has one monopoly of force. Such can be either a utopia or a dystopia, or something in between.

2. There is no longer a limitation on resources. Either we find a way to achieve near-unlimited production, or a way to achieve zero population growth and adequate production.

3. There is no longer humanity in any significant number.
