A major new book overturning our assumptions about how evolution works Earth’s natural history is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. But evolutionary biologists also point out many examples of contingency, cases where the tiniest change—a random mutation or an ancient butterfly sneeze—caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary flukes? And what does that say about life on other planets? Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be. Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

A dazzling tour of evolution in action that sheds light on one of the greatest debates in science The natural world is full of fascinating instances of convergence: phenomena like eyes and wings and tree-climbing lizards that have evolved independently, multiple times. Convergence suggests that evolution is predictable, and if we could replay the tape of life, we would get the same outcome. But there are also many examples of contingency, cases where the tiniest change - a random mutation or an ancient butterfly sneeze - caused evolution to take a completely different course. So are we humans, and all the plants and animals in the world today, inevitabilities or evolutionary freaks? What role does chance play in evolution? And what could it tell us about life on other planets? In Improbable Destinies, renowned researcher Jonathan Losos reveals what the latest breakthroughs in evolutionary biology tell us about one of the greatest ongoing debates in science. Evolution can occur far more rapidly than Darwin expected, which has opened the door to something that was previously thought impossible: experimental studies of evolution in nature. Drawing on his own work with anole lizards on the Caribbean islands, as well as studies of guppies, foxes, field mice and others being conducted around the world, Losos reveals just how rapid and predictable evolution can be. By charting the discoveries of the scientists who are rewriting our understanding of evolutionary biology, Improbable Destinies will change the way we think and talk about evolution.

Teen childbearing has risen to frighteningly high levels over the last four decades, jeopardizing the life chances of young parents and their offspring alike, particularly among minority communities. Or at least, that's what politicians on the right and left often tell us, and what the American public largely believes. But sociologist Frank Furstenberg argues that the conventional wisdom distorts reality. In Destinies of the Disadvantaged, Furstenberg traces the history of public concern over teen pregnancy, exploring why this topic has become so politically powerful, and so misunderstood. Based on over forty years of Furstenberg's research on teen childbearing, Destinies of the Disadvantaged relates how the issue emerged from obscurity to become one of the most heated social controversies in America. Both slipshod research by social scientists and opportunistic grandstanding by politicians have contributed to public misunderstanding of the issue. Although out-of-wedlock teen pregnancy rose notably between 1960 and 1990—a cause for concern given the burdens of single motherhood at a young age—this trend did not reflect a rise in the rate of overall teen pregnancies. In fact, teen pregnancy actually declined dramatically in the 1960s and 1970s. The number of unmarried teenage mothers rose after 1960, not because more young women became pregnant, but because those who did increasingly chose not to rush into marriage. Furstenberg shows how early social science research on this topic exaggerated the adverse consequences of early parenthood both for young parents and for their children. Researchers also inaccurately portrayed single teenage motherhood as a phenomenon concentrated among minorities. Both of these misapprehensions skewed subsequent political debates. The issue became a public obsession and remained so during the 1990s, even as rates of out-of-wedlock teen childbearing plummeted. Addressing teen pregnancy was originally a liberal cause, led by advocates of family planning services, legalized abortion, and social welfare programs for single mothers. The issue was later adopted by conservatives, who argued that those liberal remedies were encouraging teen parenthood. According to Furstenberg, the flexible political usefulness of the issue explains its hold on political discourse. The politics of teen parenthood is a fascinating case study in the abuse of social science for political ends. In Destinies of the Disadvantaged, Furstenberg brings that tale to life with the perspective of a historian and the insight of an insider, and provides the straight facts needed to craft effective policies to address teen pregnancy.
