The tendency of humans towards eugenics is the species way of preserving the best possible genetic offspring through indentification of beauty. What you view as beautiful is what you have to access to or what your caste qualifies you to get. Deformities, differences, and things unlike your social caste or allele group are segregated.
If humans weren't all inbred every person would have a trillion ancestors after 1000 years (vs. the 300 million total humans on the planet at that time). Aesthetic beauty and familiarity trumps diversity in the limited and related population our ancestors lived.
Key criteria: Are they noticeably unlike the others (inbred)?
Counterintuitively, the more the population grows the more uniqueness and difference is valued as the need to have genetically superior non-inbred superbabies fades.
