Book Description
The great evolutionist Mayr elucidates the subtleties of Darwin’s thought and that of his contemporaries and intellectual heirs—A. R. Wallace, T. H. Huxley, August Weisman, Asa Gray. Mayr has achieved a remarkable distillation of Darwin’s scientific thought and his legacy to twentieth-century biology.

Book Description
All But My Life is the unforgettable story of Gerda Weissmann Klein's six-year ordeal as a victim of Nazi cruelty. From her comfortable home in Bielitz (present-day Bielsko) in Poland to her miraculous survival and her liberation by American troops--including the man who was to become her husband--in Volary, Czechoslovakia, in 1945, Gerda takes the reader on a terrifying journey. Gerda's serene and idyllic childhood is shattered when Nazis march into Poland on September 3, 1939. Although the Weissmanns were permitted to live for a while in the basement of their home, they were eventually separated and sent to German labor camps. Over the next few years Gerda experienced the slow, inexorable stripping away of "all but her life." By the end of the war she had lost her parents, brother, home, possessions, and community; even the dear friends she made in the labor camps, with whom she had shared so many hardships, were dead. Despite her horrifying experiences, Klein conveys great strength of spirit and faith in humanity. In the darkness of the camps, Gerda and her young friends manage to create a community of friendship and love. Although stripped of the essence of life, they were able to survive the barbarity of their captors. Gerda's beautifully written story gives an invaluable message to everyone. It introduces them to last century's terrible history of devastation and prejudice, yet offers them hope that the effects of hatred can be overcome.

Book Description
In this lecture, the author points out that Nägeli's perspective on the evolution of the organic world has always struck him as surprising. He assumed that it had arisen from inherent internal forces and that external influences had only played a secondary and unimportant role, improving and modifying but not determining. This astute thinker stated unequivocally that, in his opinion, the course of development would have resulted in roughly the same outcome even if life conditions had remained unchanged since the beginning.

Book Description
This unique book looks at the biology of aging from a fundamentally new perspective, one based on evolutionary theory rather than traditional concepts which emphasize molecular and cellular processes. The basis for this approach lies in the fact that natural selection, as a powerful determining force, tends to decline in importance with age. Many of the characteristics we associate with aging, the author argues, are more the result of this decline than any mechanical imperative contained within organic structures. This theory in turn yields the most fruitful avenues for seeking answers to the problem of aging, and should be recognized as the intellectual core of gerontology and the foundation for future research. The author ably surveys the vast literature on aging, presenting mathematical, experimental, and comparative findings to illustrate and support the central thesis. The result is the first complete synthesis of this vital field. Evolutionary biologists, gerontologists, and all those concerned with the science of aging will find it a stimulating, strongly argued account.
