Further evidence that Hamilton was wrong about eusocial insects

What I find so fascinating about this study is that relatedness can actually under some scenarios undermine cooperation, and that when proper policing of cheating is possible, less-related individuals may have more incentive to cooperate. All that said, we are still talking about a “family” of insects, so relatedness still matters: Hamilton’s Rule may just be too simplistic.
