Not true. The process we call evolution has a two very clear and sensible goals/directions - one from the point of view of the gene and the other from the point of view of the individual (sometimes these are in conflict), but both strive towards maximum reproductive success.
Culture, social interactions, dominance hierarchies, mate selection-retention strategies, and investment in offspring are all play important aspects of human culture and evolution.
BTW this podcast course (http://oyc.yale.edu/ecology-and-evolutionary-biology/principles-of-evolution-ecology-and-behavior/) is a really great introduction to the field. Highly recommended.
Class #13 is releveant to this discussion on culture and evolution.
