Unlike humans, who came down from the trees and developed bipedal locomotion, chimpanzees have remained in the original habitat of our ancestors: the tropical rainforests of Africa.
In this book, Vernon Reynolds describes in detail the work of a large number of students and senior researchers on the wild chimpanzees of the Budongo Forest Reserve in Western Uganda. He presents a coherent and in-depth account of one chimpanzee community of more than 60 individuals living in the Sonso area in the middle of the Budongo Forest, which he and his colleagues have studied intensively over the...

What effect does the Islamic attitude toward abortion have upon the family size and growth of Muslim populations? How do the Sukuma people of Tanzania react to the birth of an abnormal child, and why do their reactions differ so radically from those of Roman Catholics in Pennsylvania? Why were one sixth of all brides in English rural parishes between the late sixteenth and early nineteenth centuries pregnant at marriage, and what does this tell us about Christian practices during that period?
No society exists in which religion does not play a significant part in the lives of ordinary...

Language is just one particularly highly developed form of primate communication. Recent years have seen increased attention to other forms: studies of animals in the wild, efforts to teach sign language to apes. This volume reflects perspectives from a variety of disciplines on the nature and function of primate signalling systems. Monkeys and apes, like people, live in a world in which they are constantly receiving and transmitting information. How can we interpret the ways in which they process it without imposing our own language-based categorizations? The problem is partly scientific,...

Fertility in animals directly reflects access to scarce resources, such as food and territory. In humans, the situation is more complex. Patterns of breast feeding, contraception and ideas about age of marriage and desired family size all affect fertility. This book explores the relation among these factors and access to scarce resources, via income, education and other forms of status.

In this book, the gap between socio-ecology and population demography is bridged, by showing how animals and humans adjust their fertility to environmental conditions.
