Replicating human behavior accurately is still a challenge and is an active area of research in AI specifically because no one knows in detail the answer to your question.
In theory, you would use some or all of the above techniques in an attempt to evolve a similar (cooperation-heavy, communication-dependent) solution to the same kind of tribal and population survival problems under sensory and physcal limitations that the ancestors of humans evolved in response to.  
In practice it is not even clear how such tribal and population survival problems involving limited sensory information and physical limitations could be meaningfully implemented, much less how to model genetic selection in such an environment.
