Looking at both population and land tenure dynamics in their historical context, this study challenges the view that the 1969 conflict between El Salvador and Honduras was primarily a response to population pressure. The author demonstrates that land scarcity, a principal cause of the war, was largely a product of the concentration of landholdings. The analysis focuses on the emigration of 300,000 Salvadoreans to Honduras in the years before the war, inquiring into the reasons for the emigration, its impact on local agricultural economies, and its relation to the conflict. Answers to these...

Is inbreeding harmful? Are human beings and other primates naturally inclined to mate with their closest relatives? Why is incest widely prohibited? Why does the scope of the prohibition vary from society to society? Why does incest occur despite the prohibition? What are the consequences? After one hundred years of intense argument, a broad consensus has emerged on the first two questions, but the debate over the others continues. That there is a biological basis for the avoidance of inbreeding seems incontrovertible, but just how injurious inbreeding really is for successive generations...

Charles Darwin's "On the Origins of Species" had two principal goals: to show that species had not been separately created and to show that natural selection had been the main force behind their proliferation and descent from common ancestors. In "Coevolution," the author proposes a powerful new theory of cultural evolution--that is, of the descent with modification of the shared conceptual systems we call "cultures"--that is parallel in many ways to Darwin's theory of organic evolution.
The author suggests that a process of cultural selection, or preservation by preference, driven chiefly...
