Charles Darwin is often credited with discovering evolution through natural selection, but the idea was not his alone. The naturalist Alfred Russel Wallace, working independently, saw the same process at work in the natural world and elaborated much the same theory. Their important scientific contributions made both men famous in their lifetimes, but Wallace slipped into obscurity after his death, while Darwin’s renown grew. Dispelling the misperceptions that continue to paint Wallace as a secondary figure, James Costa reveals the two naturalists as true equals in advancing one of the greatest scientific discoveries of all time.

Analyzing Wallace’s “Species Notebook,” Costa shows how Wallace’s methods and thought processes paralleled Darwin’s, yet inspired insights uniquely his own. Kept during his Southeast Asian expeditions of the 1850s, the notebook is a window into Wallace’s early evolutionary ideas. It records his evidence-gathering, critiques of anti-evolutionary arguments, and plans for a book on “transmutation.” Most important, it demonstrates conclusively that natural selection was not some idea Wallace stumbled upon, as is sometimes assumed, but was the culmination of a decade-long quest to solve the mystery of the origin of species.

Wallace, Darwin, and the Origin of Species also reexamines the pivotal episode in 1858 when Wallace sent Darwin a manuscript announcing his discovery of natural selection, prompting a joint public reading of the two men’s papers on the subject. Costa’s analysis of the “Species Notebook” shines a new light on these readings, further illuminating the independent nature of Wallace’s discoveries.

In Why Lyrics Last, the internationally acclaimed critic Brian Boyd turns an evolutionary lens on the subject of lyric verse. He finds that lyric making, though it presents no advantages for the species in terms of survival and reproduction, is “universal across cultures because it fits constraints of the human mind.” An evolutionary perspective— especially when coupled with insights from aesthetics and literary history—has much to tell us about both verse and the lyrical impulse.

Boyd places the writing of lyrical verse within the human disposition “to play with pattern,” and in an extended example he uncovers the many patterns to be found within Shakespeare’s Sonnets. Shakespeare’s bid for readership is unlike that of any sonneteer before him: he deliberately avoids all narrative, choosing to maximize the openness of the lyric and demonstrating the power that verse can have when liberated of story.

In eschewing narrative, Shakespeare plays freely with patterns of other kinds: words, images, sounds, structures; emotions and moods; argument and analogy; and natural rhythms, in daily, seasonal, and life cycles. In the originality of his stratagems, and in their sheer number and variety, both within and between sonnets, Shakespeare outdoes all competitors. A reading of the Sonnets informed by evolution is primed to attend to these complexities and better able to appreciate Shakespeare’s remarkable gambit for immortal fame.

What does it mean to be female? Sarah Blaffer Hrdy--a sociobiologist and a feminist--believes that evolutionary biology can provide some surprising answers. Surprising to those feminists who mistakenly think that biology can only work against women. And surprising to those biologists who incorrectly believe that natural selection operates only on males.

In The Woman That Never Evolved we are introduced to our nearest female relatives competitive, independent, sexually assertive primates who have every bit as much at stake in the evolutionary game as their male counterparts do. These females compete among themselves for rank and resources, but will bond together for mutual defense. They risk their lives to protect their young, yet consort with the very male who murdered their offspring when successful reproduction depends upon it. They tolerate other breeding females if food is plentiful, but chase them away when monogamy is the optimal strategy. When "promiscuity" is an advantage, female primates--like their human cousins--exhibit a sexual appetite that ensures a range of breeding partners. From case after case we are led to the conclusion that the sexually passive, noncompetitive, all-nurturing woman of prevailing myth never could have evolved within the primate order.

Yet males are almost universally dominant over females in primate species, and Homo sapiens is no exception. As we see from this book, women are in some ways the most oppressed of all female primates. Sarah Blaffer Hrdy is convinced that to redress sexual inequality in human societies, we must first understand its evolutionary origins. We cannot travel back in time to meet our own remote ancestors, but we can study those surrogates we have--the other living primates. If women --and not biology--are to control their own destiny, they must understand the past and, as this book shows us, the biological legacy they have inherited.
