This volume considers the genetic variability of human populations, particularly in the tropics: its origins and maintenance, and its contribution to the phenotypic variability of complex characters. The first section deals with the ways of analysing genetic variation and provides a valuable review of relevant developments in molecular biology. The origin and maintenance of genetic diversity is considered in the second section with data presented for Pacific, African, Asian and Central American populations. The final section concerns characters in which the genetic contribution to variability is complex and shows how such characters may be used to elucidate biological problems of affinity and differentiation, of adaptation and survival. Published as part of the Decade of the Tropics research programme of the International Union of Biological Sciences, this volume will be of particular interest to human geneticists, physical and biological anthropologists.

This special symposium volume of the SSHB explores the biological effects of human isolation and migration, and how the situations to which they give rise help to elucidate a variety of biological problems, ranging from evolutionary change to disease etiology. The majority of the case studies presented here are by Asian investigators, and provide a uniquely accessible source of information. Besides documenting the results, the book illustrates the different methods employed in such studies. It will be invaluable to those contemplating similar investigations elsewhere, and will be of interest to researchers in a range of disciplines including epidemiology, clinical medicine, demography, anthropology, genetics and evolutionary biology.

Working capacity is the physiological key to understanding man's ability, in technically less advanced communities, to exploit his environment, and hence to understanding his role in the ecological balance. In this volume the knowledge of working capacity in tropical populations is reviewed in a series of illustrative papers. Topics cover the measurement of working capacity in populations: the functional consequences of malnutrition; growth, size and muscular efficiency; ethnic differences in working capacity; energy; expenditure and endemic disease; and energy flow in tropical ecosystems. These papers and their ensuing discussions lead to a series of recommendations on studies to be incorporated in the Decade of the Tropics research programme of the International Union of Biological Sciences.
