Adaptation Natural Selection

Adaptation and Natural Selection - Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thought is a 1966 book by the American George C. Williams on evolutionary biology.

Natural selection - Natural selection is the metaphor Charles Darwin used in 1859 to name the process he postulated to drive the adaptation of organisms to their environments and the origin of new species. Natural selection, together with the rules of inheritance discovered by Gregor Mendel at about the same time, stand at the basis of modern evolutionary biology.

Adaptation - A biological adaptation is an anatomical structure, physiological process or behavioral trait of an organism that has evolved over a period of time by the process of natural selection such that it increases the expected long-term reproductive success of the organism. The term adaptation is also sometimes used as a synonym for natural selection, but most biologists discourage this usage.

On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection - Two scientific papers; On the Tendency of Species to form Varieties by Alfred Russel Wallace and on the Perpetuation of Varieties and Species by Natural Means of Selection by Charles Darwin were presented to the Linnean Society of London in 1858 that first publicised Darwin ā€” Wallace theory of evolution by natural selection. Darwin's On the Origin of Species would follow a year later.

Adaptation and Natural Selection: A Critique of Some Current Evolutionary Thought by George Christopher Williams,

Biological evolution is a fact--but the many conflicting theories of evolution remain controversial even today. In 1966, simple Darwinism, which holds that evolution functions primarily at the level of the individual organism, was threatened by opposing concepts such as group selection, a popular idea stating that evolution acts to select entire species rather than individuals. George Williams's famous argument in favor of the Darwinists struck a powerful blow to those in opposing camps. His "Adaptation adaptation natural selection and Natural Selection, now a classic of science literature, is a thorough adaptation natural selection and convincing essay in defense of Darwinism; its suggestions for developing effective principles for dealing with the evolution debate adaptation natural selection and its relevance to many fields outside biology ensure the timelessness of this critical work.

The Evolution of Darwinism: Selection, Adaptation and Progress in Evolutionary Biology

No other scientific theory has had as great an impact on our understanding of the world as Darwin's theory outlined in his Origin of Species. Yet the theory has been the subject of controversy from its very beginning. This book focuses on three issues of debate in Darwin's theory of evolution--the nature of selection, the nature adaptation natural selection and scope of adaptation, adaptation natural selection and the question of evolutionary progress. It traces the varying interpretations to which these issues were subjected historically through the fierce contemporary debates continuing to rage.
