Thank you for the detailed critique! The second model ensures that the probability to interact with kin varies over time. While the more recent mutations don’t have kin to interact with, older ones either die out or create an entire group of descendants, and the group itself interacts with itself and few neighbors. The bigger the group is, the smaller is r and the harder it is for defection to spread further.
