Differences in physique in men called ‘Smith’ or ‘Tailor’ considered as results of a genetic effect dating back over several centuries

Differences in answers on a questionnaire regarding weight, ‘solidity’, putative suitability for sports involving strength as opposed to agility, occupations calling for strenght or agility respectively, and personal preferences of hobbies demanding strength or agility were ascertained between 110 male bearers of the name Smith and the same number of bearers of the name Tailor. Observed differences were related to a hypothesis involving genetic effects going back over centuries and depending on bodily characteristics related to the professions of smith and tailor respectively. The size of the observed differences is such as to suggest assortative mating with respect to the traits involved, as well as the isolation of special breeding populations.
