Document Summary
Some individuals care for ofspring that is not their own at the expense of their own reproducion. High skew only one breeding female and only one breeding male in the group and the reproducion is skewed to those few individuals. Some groups will have low skew where many individuals in the group will get the chance to reproduce, but will sill help with others" young. Joint nesing more than one female will lay their eggs in the same nest. Allocare/alloparental care caring for someone else"s ofspring. If both individuals are beneiing from cooperaive behaviour, there is no mystery. The issue is, is that most cooperaive acts that we see, there is a donor and recipient. One partner is doing costly things, and the other is beneiing. Way beter to hang back and allow others to do the costly acivity. Cheaing mutants spread because they can parasiize cooperaive behaviour.
