Natural Selections

During the Depression the Canadian National Parks Branch was under pressure to make the park system truly national, to bring the advantages of parks to all provinces. In Atlantic Canada, however, it found itself dealing with an environment that was far different from what it was accustomed to in Western Canada. The land areas were smaller, flatter, and, having been settled for generations, could hardly be considered wild. Wildlife was smaller and less numerous.

Natural Selections traces the history of the first four parks in Atlantic Canada through the selection, expropriation, development, and management stages. Alan MacEachern shows how the Parks Branch's preconceptions about the landscape and people of the region shaped the parks created there. In doing so he details the evolution of the park system, from the conservation movement early in the century to the rise of the ecology movement. MacEachern analyzes Parks Canada's efforts to fulfill its twin mandates of preservation and use, arguing that the agency never favoured one over the other but oscillated between more or less interventionist in ensuring both. Touching on a wide range of matters - from landscape aesthetics to tourism promotion, from DDT to Martin Luther King - Natural Selections expands our understanding of the relation between nature and culture in the twentieth century.

In 1859 Darwin described a deceptively simple mechanism that he called "natural selection," a combination of variation, inheritance, and reproductive success. He argued that this mechanism was the key to explaining the most puzzling features of the natural world, and science and philosophy were changed forever as a result. The exact nature of the Darwinian process has been controversial ever since, however. Godfrey-Smith draws on new developments in biology, philosophy of science, and other fields to give a new analysis and extension of Darwin's idea. The central concept used is that of a "Darwinian population," a collection of things with the capacity to undergo change by natural selection. From this starting point, new analyses of the role of genes in evolution, the application of Darwinian ideas to cultural change, and "evolutionary transitions" that produce complex organisms and societies are developed. Darwinian Populations and Natural Selection will be essential reading for anyone interested in evolutionary theory

In his groundbreaking book ""Natural Selection"", Charles Darwin explained his theory that evolution is driven by adaptation of species to their environmental surroundings. From the tiniest microbe to the largest whale, all organisms have changed over vast expanses of time due to the forces of natural selection. This new title in the ""Science Foundations"" series provides an overview of the processes and causes that drive natural selection and the principles that explain how it operates, using numerous diverse organisms as examples. ""Natural Selection"" promotes a solid understanding of how organisms change over the course of generations and how current biodiversity came to be.

Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate.
