The Natural History of Inbreeding and Outbreeding

Theoretical and Empirical Perspectives

Edited by Nancy Wilmsen Thornhill

University of Chicago Press, 1993

Inbreeding, the mating of close kin, and outbreeding, the mating of distant relatives or unrelated organisms, have long been important subjects to evolutionary biologists. Inbreeding reduces genetic diversity in a population, increasing the likelihood that genetic defects will become widespread and deprive a population of the diversity it may need to cope with its environment. Most plants and animals have evolved behavioral and morphological mechanisms to avoid inbreeding. However, today many endangered species exist only in small, very isolated populations where inbreeding is unavoidable, so it has become a concern for conservationists. In this volume, twenty-six experts in evolution, behavior, and genetics examine the causes and consequences of inbreeding.

The authors ask whether inbreeding is as problematic as biologists have thought, under what ecological conditions inbreeding occurs, and whether organisms that inbreed have mechanisms to dampen the anticipated problems of reduced genetic variation. The studies, including theoretical and empirical work on wild and captive populations, demonstrate that many plants and animals inbreed to a greater extent than biologists have thought, with variable effects on individual fitness. Graduate students and researchers in evolutionary biology, animal behavior, ecology, and conservation biology will welcome this wide-ranging collection.

The Nature of Selection

Evolutionary Theory in Philosophical Focus

Elliott Sober

University of Chicago Press, 1993

The Nature of Selection is a straightforward, self-contained introduction to philosophical and biological problems in evolutionary theory. It presents a powerful analysis of the evolutionary concepts of natural selection, fitness, and adaptation and clarifies controversial issues concerning altruism, group selection, and the idea that organisms are survival machines built for the good of the genes that inhabit them.

"Sober's is the answering philosophical voice, the voice of a first-rate philosopher and a knowledgeable student of contemporary evolutionary theory. His book merits broad attention among both communities. It should also inspire others to continue the conversation."-Philip Kitcher, Nature

"Elliott Sober has made extraordinarily important contributions to our understanding of biological problems in evolutionary biology and causality. The Nature of Selection is a major contribution to understanding epistemological problems in evolutionary theory. I predict that it will have a long lasting place in the literature."-Richard C. Lewontin

Nature's Prophet

Alfred Russel Wallace and His Evolution from Natural Selection to Natural Theology

Michael A. Flannery

University of Alabama Press, 2018

An astute study of Alfred Russel Wallace’s path to natural theology.

A spiritualist, libertarian socialist, women’s rights advocate, and critic of Victorian social convention, Alfred Russel Wallace was in every sense a rebel who challenged the emergent scientific certainties of Victorian England by arguing for a natural world imbued with purpose and spiritual significance. Nature’s Prophet:Alfred Russel Wallace and His Evolution from Natural Selection to Natural Theology is a critical reassessment of Wallace’s path to natural theology and counters the dismissive narrative that Wallace’s theistic and sociopolitical positions are not to be taken seriously in the history and philosophy of science.

Author Michael A. Flannery provides a cogent and lucid account of a crucial—and often underappreciated—element of Wallace’s evolutionary worldview. As co-discoverer, with Charles Darwin, of the theory of natural selection, Wallace willingly took a backseat to the well-bred, better known scientist. Whereas Darwin held fast to his first published scientific explanations for the development of life on earth, Wallace continued to modify his thinking, refining his argument toward a more controversial metaphysical view which placed him within the highly charged intersection of biology and religion.

Despite considerable research into the naturalist’s life and work, Wallace’s own evolution from natural selection to natural theology has been largely unexplored; yet, as Flannery persuasively shows, it is readily demonstrated in his writings from 1843 until his death in 1913. Nature’s Prophet provides a detailed investigation of Wallace’s ideas, showing how, although he independently discovered the mechanism of natural selection, he at the same time came to hold a very different view of evolution from Darwin.

Ultimately, Flannery shows, Wallace’s reconsideration of the argument for design yields a more nuanced version of creative and purposeful theistic evolution and represents one of the most innovative contributions of its kind in the Victorian and Edwardian eras, profoundly influencing a later generation of scientists and intellectuals.
