I recommend it because it is very relevant. For instance because altruism is one of the core values that drive social network use and bind people that relate to each other and do transactions, including commercial ones. And it is the basis for P2P co-operation and collaboration.
The famous Harvard scholar Martin A. Nowak explained in several books more fundamental processes in Evolutionary Dynamics which depend on altruism in groups : Supercooperators – Why Cooperation not Competition is the Key to Life – Mustread !!
