And the same with raising children. Group goals are met by everyone becoming a specialist in what they do best, as long as it contributes in some way. Eugenicists can be classified as breeders, enforcers, or nurturers. That is, there will be those who want to participate but not necessarily pass on their own genes for various reasons. Everyone will be productive and further the cause, but not everyone needs to do it in the same manner.
Specialization is efficiency.
And our genes run throughout the tribe, not in individual families, though family cohesiveness will not be frowned upon as a natural instinct. V. Racial purity is not a valid concept for a eugenicist. Since we are breeding and genetically splicing our way into a new species, racial components are ever changing. The only valid concept is one of group cohesiveness. We want to be with people who are like us, that is similarity in phenotype bonds the group together, not racial purity.
