    The claim you're purporting isn't there. It only concerns the fitness benefits of avoiding consanguinity.

    Of course any notion of genetic diversity would include consanguinity: by definition, less consanguinity = more genetically diverse. The reporting as well as the study's authors explicitly say "diverse genetic backgrounds," meaning that the study's range far exceeds the effects of inbreeding.


    Those who are born to parents from diverse genetic backgrounds tend to be taller and have sharper thinking skills than others, the major international study has found.

    The effect is pretty small though, so maybe who cares??

    That's not the definition:

    "In clinical genetics, consanguinity is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0.0156.where (F) represents the proportion of genetic loci at which the child of a consanguineous couple might inherit identical gene copies from both parents.[18]It is common to distinguish first-degree cousins, second-degree cousins, and often also third-degree cousins. Since comparatively few people can trace their full family tree for more than four generations, the identity of fourth-degree cousins often cannot be established. Also, at a genetic level, half-fourth cousins typically do not exhibit greater genetic similarity with one another than with any other individual from the same population.[19]


    It's a major problem in Arab populations:

    In other words, relating to genetic diversity.
