Book Description
Over half of all births to young adults in the United States now occur outside of marriage, and many are unplanned. The result is increased poverty and inequality for children. The left argues for more social support for unmarried parents; the right argues for a return to traditional marriage. In Generation Unbound, Isabel V. Sawhill offers a third approach: change "drifters" into "planners." In a well-written and accessible survey of the impact of family structure on child well-being, Sawhill contrasts "planners," who are delaying parenthood until after they marry, with "drifters," who are having unplanned children early and outside of marriage. These two distinct patterns are contributing to an emerging class divide and threatening social mobility in the United States. Sawhill draws on insights from the new field of behavioral economics, showing that it is possible, by changing the default, to move from a culture that accepts a high number of unplanned pregnancies to a culture in which adults only have children when they are ready to be a parent.

Book Description
Introductory guide to human population genetics and microevolutionary theory Providing an introduction to mathematical population genetics, Human Population Genetics gives basic background on the mechanisms of human microevolution. This text combines mathematics, biology, and anthropology and is best suited for advanced undergraduate and graduate study. Thorough and accessible, Human Population Genetics presents concepts and methods of population genetics specific to human population study, utilizing uncomplicated mathematics like high school algebra and basic concepts of probability to explain theories central to the field. By describing changes in the frequency of genetic variants from one generation to the next, this book hones in on the mathematical basis of evolutionary theory. Human Population Genetics includes: Helpful formulae for learning ease Graphs and analogies that make basic points and relate the evolutionary process to mathematical ideas Glossary terms marked in boldface within the book the first time they appear In-text citations that act as reference points for further research Exemplary case studies Topics such as Hardy-Weinberg equilibrium, inbreeding, mutation, genetic drift, natural selection, and gene flow Human Population Genetics solidifies knowledge learned in introductory biological anthropology or biology courses and makes it applicable to genetic study.

Book Description
The advances made possible by the development of molecular techniques have in recent years revolutionized quantitative genetics and its relevance for population genetics. Population Genetics and Microevolutionary Theory takes a modern approach to population genetics, incorporating modern molecular biology, species-level evolutionary biology, and a thorough acknowledgment of quantitative genetics as the theoretical basis for population genetics. Logically organized into three main sections on population structure and history, genotype-phenotype interactions, and selection/adaptation Extensive use of real examples to illustrate concepts Written in a clear and accessible manner and devoid of complex mathematical equations Includes the author's introduction to background material as well as a conclusion for a handy overview of the field and its modern applications Each chapter ends with a set of review questions and answers Offers helpful general references and Internet links

Book Description
"A dazzling debut, establishing Namwali Serpell as a writer on the world stage."--Salman Rushdie, The New York Times Book Review Longlisted for the Center for Fiction First Novel Prize - "Clear-eyed, energetic and richly entertaining."--The Washington Post NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New York Times Book Review - Time - Tordotcom - Kirkus Reviews - BookPage 1904. On the banks of the Zambezi River, a few miles from the majestic Victoria Falls, there is a colonial settlement called The Old Drift. In a smoky room at the hotel across the river, an Old Drifter named Percy M. Clark, foggy with fever, makes a mistake that entangles the fates of an Italian hotelier and an African busboy. This sets off a cycle of unwitting retribution between three Zambian families (black, white, brown) as they collide and converge over the course of the century, into the present and beyond. As the generations pass, their lives--their triumphs, errors, losses and hopes--emerge through a panorama of history, fairytale, romance and science fiction. From a woman covered with hair and another plagued with endless tears, to forbidden love affairs and fiery political ones, to homegrown technological marvels like Afronauts, microdrones and viral vaccines, this gripping, unforgettable novel is a testament to our yearning to create and cross borders, and a meditation on the slow, grand passage of time. Praise for The Old Drift "An intimate, brainy, gleaming epic . . . This is a dazzling book, as ambitious as any first novel published this decade."--Dwight Garner, The New York Times "A founding epic in the vein of Virgil's Aeneid . . . though in its sprawling size, its flavor of picaresque comedy and its fusion of family lore with national politics it more resembles Salman Rushdie's Midnight's Children."--The Wall Street Journal "A story that intertwines strangers into families, which we'll follow for a century, magic into everyday moments, and the story of a nation, Zambia."--NPR

Book Description
Now updated for its second edition, Population Genetics is the classic, accessible introduction to the concepts of population genetics. Combining traditional conceptual approaches with classical hypotheses and debates, the book equips students to understand a wide array of empirical studies that are based on the first principles of population genetics. Featuring a highly accessible introduction to coalescent theory, as well as covering the major conceptual advances in population genetics of the last two decades, the second edition now also includes end of chapter problem sets and revised coverage of recombination in the coalescent model, metapopulation extinction and recolonization, and the fixation index.
