This book is a success story. It explains two long-running puzzles of the theory of natural selection. How can natural selection favour those, like the ant, that renounce tooth and claw in favour of the public-spirited ways of the commune? How can it explain the peacock's tail, flamboyant and a burden to its bearer; surely selection would act against useless ornamentation? Helena Cronin's enthralling account blends history, science and philosophy in a gripping tale that is scholarly, entertaining and eminently readable. The hardback edition was selected by Nature as one of the best scientific books in 1992. Also the New York Times chose it as one of their best books of 1992. The author divides her time between the Philosophy Department at the London School of Economics and the Zoology Department at Oxford.
A new novel from Angela Cervantes that uses the story of Frida Kahlo to help readers discover the true power of heritage, art, and family.

Darwin identified the existence of separate male and female gametes as one of the central mysteries of evolutionary biology. 150 years later, the question of why male gametes exist remains an intriguing puzzle. In this, the first book solely devoted to the evolution of anisogamy, top theorists in the field explore why gamete dimorphism characterizes nearly all plants and animals. Did separate male and female gametes evolve as a result of competition, or does anisogamy instead represent selection for cooperation? If disruptive selection drove the evolution of anisogamy, with male gametes focused on search and fusion, and female gametes provisioning the new zygote, why do some algal species continue to produce gametes of a single size? Does sperm limitation, or escape from infection, better explain the need for extremely small, highly mobile sperm? Written by leaders in the field, this volume offers an authoritative and cutting-edge overview of evolutionary theory.

A collection of animal fables told by the Greek slave Aesop.
Male-male rivalry and female passive choice, the two principal tenets of Darwinian sexual selection, raise important ethical questions in The Descent of Man--and in the decades since--about the subjugation of women. If female choice is a key component of evolutionary success, what impact does the constraint of women's choices have on society? The elaborate courtship plots of 19th century Spanish novels, with their fixation on suitors and selectors, rivalry, and seduction, were attempts to grapple with the question of female agency in a patriarchal society. By reading Darwin through the lens of the Spanish realist novel and vice versa, Travis Landry brings new insights to our understanding of both: while Darwin's theories have often been seen as biologically deterministic, Landry asserts that Darwin's theory of sexual selection was characterized by an open ended dynamic whose oxymoronic emphasis on "passive" female choice carries the potential for revolutionary change in the status of women.
