A surprising new description of how Homo sapiens originated in Africa and spread around the world.
In his first book, Reich (Genetics/Harvard Medical School) describes the revolution in his specialty, genomics, the branch of molecular biology that analyzes our genes, units of DNA that transmit hereditary information from parent to offspring. Since 2001, when scientists sequenced the human genome for the first time, technology has massively reduced the cost of the procedure. At the same time, researchers have become incredibly adept at extracting DNA from bones as old as 400,000 years. Readers who pay close attention will understand Reich’s explanation of what this reveals. As generations pass, strings of DNA in the genome split and recombine, and errors (mutations) appear in individual genes. Comparing one genome to another reveals the relationship between populations more accurately than comparing bones. Mutations appear at a regular rate, allowing researchers to measure time elapsed as evolution proceeds. “Since 2009,” writes the author, “…whole-genome data have begun to challenge long-held views in archaeology, history, anthropology, and even linguistics—and to resolve controversies in those fields. The ancient DNA revolution is rapidly disrupting our assumptions about the past.” Most agree that migrants from Turkey brought agriculture to Europe about 8,000 years ago. They once agreed that these migrants brought Indo-European languages spoken throughout most Western nations, but the studies in genomics reveal that the languages arrived with later migrants: a “ghost population” from the Russian steppes who also moved east and contributed genes to American Indians. Throughout the book, Reich includes numerous timelines, graphs, maps, and diagrams to assist readers in visualizing his material, but those who are not scientifically inclined may find the narrative difficult to follow—though ultimately rewarding.

A neurosurgeon with a passion for literature tragically finds his perfect subject after his diagnosis of terminal lung cancer.
Writing isn’t brain surgery, but it’s rare when someone adept at the latter is also so accomplished at the former. Searching for meaning and purpose in his life, Kalanithi pursued a doctorate in literature and had felt certain that he wouldn’t enter the field of medicine, in which his father and other members of his family excelled. “But I couldn’t let go of the question,” he writes, after realizing that his goals “didn’t quite fit in an English department.” “Where did biology, morality, literature and philosophy intersect?” So he decided to set aside his doctoral dissertation and belatedly prepare for medical school, which “would allow me a chance to find answers that are not in books, to find a different sort of sublime, to forge relationships with the suffering, and to keep following the question of what makes human life meaningful, even in the face of death and decay.” The author’s empathy undoubtedly made him an exceptional doctor, and the precision of his prose—as well as the moral purpose underscoring it—suggests that he could have written a good book on any subject he chose. Part of what makes this book so essential is the fact that it was written under a death sentence following the diagnosis that upended his life, just as he was preparing to end his residency and attract offers at the top of his profession. Kalanithi learned he might have 10 years to live or perhaps five. Should he return to neurosurgery (he could and did), or should he write (he also did)? Should he and his wife have a baby? They did, eight months before he died, which was less than two years after the original diagnosis. “The fact of death is unsettling,” he understates. “Yet there is no other way to live.”

PERSPECTIVES
Occasionally wonky but overall a good case for how the dismal science can make the world less—well, dismal.
“Quality of life means more than just consumption”: Two MIT economists urge that a smarter, more politically aware economics be brought to bear on social issues.
It’s no secret, write Banerjee and Duflo (co-authors: Poor Economics: A Radical Rethinking of the Way To Fight Global Poverty, 2011), that “we seem to have fallen on hard times.” Immigration, trade, inequality, and taxation problems present themselves daily, and they seem to be intractable. Economics can be put to use in figuring out these big-issue questions. Data can be adduced, for example, to answer the question of whether immigration tends to suppress wages. The answer: “There is no evidence low-skilled migration to rich countries drives wage and employment down for the natives.” In fact, it opens up opportunities for those natives by freeing them to look for better work. The problem becomes thornier when it comes to the matter of free trade; as the authors observe, “left-behind people live in left-behind places,” which explains why regional poverty descended on Appalachia when so many manufacturing jobs left for China in the age of globalism, leaving behind not just left-behind people but also people ripe for exploitation by nationalist politicians. The authors add, interestingly, that the same thing occurred in parts of Germany, Spain, and Norway that fell victim to the “China shock.” In what they call a “slightly technical aside,” they build a case for addressing trade issues not with trade wars but with consumption taxes: “It makes no sense to ask agricultural workers to lose their jobs just so steelworkers can keep theirs, which is what tariffs accomplish.” Policymakers might want to consider such counsel, especially when it is coupled with the observation that free trade benefits workers in poor countries but punishes workers in rich ones.
