It is known from theoretician in the field of kin selection that kin selection (inclusive fitness theory) and group selection are actually two sides of the same coin. In other words, these two concepts are actually only one single process.

**Questions**

* Is group selection equivalent to kin selection for any evolutionary game or exclusively for the prisoner's dilemna?
* Can you please provide an intuitive explanation of why kin- and group-selection are the same thing?
