It's still a mystery to me how it is possible, from a merely logical point of view, that two groups are more diverse internally than between them. Especially (but not necessarily) when all the elements of one group are different from the element of the other group for at least one constant characteristic.
- twa19999 9y agoIt's simple: there are just a few defining traits for each race: skin colour, hair, shape of the eyes and nose. There are just few genes that control those. There are also hundreds or thousands of genes that control other traits, such as genetically conditioned diseases, immune system, IQ, physical endurance, character traits, etc. That's why if you measure diversity by number of genes you can get such a seemingly paradoxical result.
