Population genetics theory has continually expanded the range of biological phe nomena incorporated in its models. First random mating, then natural selection, genetic drift, and more recently linkage have been intensively investigated. Two of the most active areas of current work concern variable selection coefficients and FELSENSTEIN effects of geography. Together with work on linkage, on testing of the neutrality hypothesis, and on the population genetics of ecological phenomena, these areas account for a large fraction of the effort in contemporary theoretical population genetics. The reader will find the reviews by Christiansen & Feldman (13a) and Hedrick (53a) useful sources of further information. The review by Gould & John ston (4Ia) surveys empirical studies of geographic variation. SELECTION VARYING WITH TIME Infinite Populations It has frequently been claimed that environ mental variation, of whatever sort, has an inherent tendency to bring about or maintain genetic variability. The reasoning behind this is no more subtle, no more convincing, than a feeling that genetic variation is necessary to give the population options in the face of environmental variation. With respect to temporal variation in fitness values, the first successful attempt to deal with this question was the work of Dempster
