Seasonality has effects on a wide range of human functions and activities, and is important in the understanding of human-environment relationships. In this volume, contributors including human biologists, anthropologists, physiologists and nutritionists consider many of the different ways in which seasonality influences human biology and behaviour.

This volume looks at the relationship between specific aspects of Third World cities and human health. Rapid and extensive urbanization of the less developed nations is perhaps the most dramatic demographic phenomenon of our times, but its impact on human biology is not well understood. Here, a cross-section of work is presented on this subject allowing human biologists, urban planners, public health workers, and other specialists to assess our knowledge and the current approaches available to increase it. Contributions fall into two groups: studies of urban ecology including the social,...

The public is now paying considerable attention to the use of molecular evidence in studies of human diversity and origins. Much of the early work in this area was based on evidence from mitochondrial DNA, but this has now been supplemented by important new information from nuclear DNA from both Y chromosomes and the autosomes. The bulk of the material available is from living populations, but this is being extended by the study of DNA from archaic populations. The underlying models used in interpreting this evidence are based on the neutral theory of molecular evolution, but also consider...
