ABSTRACT
In the global village all humans become each other’s genetic competitor, regardless of intent. Ethnic kinship (ethnic genetic interest) only exists in relation to other ethnies as genetic competitors. Ethnic genetic interest is lost when all or part of an ethny is replaced by another ethny. Immigration effectively replaces part of the native population when it does not permanently raise the territory’s carrying capacity by an amount sufficient to allow for the immigrants. Hamilton’s theory allows us to express ethnic genetic interest as an equivalent number of children. Asymmetric immigration between closely related ethnies replaces native children in the receiving population by a small amount while immigration from genetically distant populations has large effects.
