Ants have a intrinsic instinct to help the whole colony mostly because they are related the the entire colony. I may have an evolutionary interest in supporting my nieces since they are my sister's children. However, I probably don't have an evolutionary interest in supporting my nephew since he is my wife's sister's child. Biologically I have zero relation to him.
