[ExI] Out breeding

[Tara Maya]

I assume humans could figure it out the same as other animals, not through cognition but through evolution. 

The thing I find odd about our species is that the females leave the pack and travel. In almost all mammals, males leave and travel to find females. This is because females provide the majority of childcare. For humans to have reversed it implies that human males, or at least the parents of human males, provide a great deal more childcare than in most extant mammals. In fact, I think grandparents are even more rare than male child-care patterns.
