For 926 persons aged 5 years and over, a large majority of the population of three western Newfoundland communities, associations of ocular refraction with inbreeding (Wright's F) have been evaluated. Some evidence was found among children of a tendency towards myopia with increasing homozygosity and a strong such tendency in the elderly (over 60) was found. No relationship of refraction to F was apparent for persons aged 15–60 years. When the strong relationship of refraction value to nearwork activity was taken into account the relationship to F was enhanced. [ABSTRACT FROM PUBLISHER]

The article presents a review of studies in the physical anthropology of the modern man which concerns papers that have appeared in the period from mid-1969 to mid-1971. This literature review aims to show how much activity there is in each major topic of investigation in the biological study of populations of man that exists, and to pick out any trend in investigation that may be detectable. To limit the range of the study, several topics including behavior studies, psychometric investigations, descriptive osteometry, and epidemiological works relating to particular disease states have been excluded.
