PALEOFANTASY

WHAT EVOLUTION REALLY TELLS US ABOUT SEX, DIET, AND HOW WE LIVE

Zuk (Univ. of California, Riverside; Sex on Six Legs: Lessons on Life, Love, and Language from the Insect World, 2011, etc.) takes on those who say we are ill-suited to modern life because we are trapped in our Stone Age bodies.

That’s pure “paleofantasy,” writes the author, and a denial of evolution. Humans emerged in the Pleistocene, beginning 1 million years ago, and have continued to evolve since. Zuk cites dozens of studies of changes in gene frequencies (the mark of evolution) when our genomes are compared with ancient DNA. One classic example is the ability of many adults to digest milk, thanks to the retention of a working lactase enzyme. Prior to the birth of agriculture and the domestication of animals—only a few thousand years ago—the lactase gene was turned off in early childhood. Adaptations to living at high altitudes are also recent, and genetic analyses show that Andean dwellers accomplish it differently than Tibetans. These and countless other examples attest to the continued interactions of our species and cultures with nature and the environment, with consequences that affect diet, disease risk/resistance and lifestyles. So it makes no sense that we should eat the “paleo” diet of meat and root vegetables like hunter-gatherers, run barefoot (as in pursuit of game) or take as models of sex behavior what our primate friends do. Zuk is particularly sharp in this area, pointing to how diverse sexual behavior is for chimps, bonobos, gorillas, gibbons and orangutans. The mistake that the back-to-paleo folks make is the belief that human evolution stopped at some point thousands of years ago. Zuk explains that evolution (in all organisms) can and does happen by genetic drift (an isolated group may, over time, concentrate particular genes), by gene inflow (when new groups mix with an existing group), by mutation (gene errors) and by natural selection, which looks at traits associated with greater reproductive success. Nothing beats good hard data to debunk myths, and Zuk offers plenty.

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.”

A moving meditation on mortality by a gifted writer whose dual perspectives of physician and patient provide a singular clarity.

A PEOPLE'S HISTORY OF THE UNITED STATES

For Howard Zinn, long-time civil rights and anti-war activist, history and ideology have a lot in common. Since he thinks that everything is in someone's interest, the historian—Zinn posits—has to figure out whose interests he or she is defining/defending/reconstructing (hence one of his previous books, The Politics of History). Zinn has no doubts about where he stands in this "people's history": "it is a history disrespectful of governments and respectful of people's movements of resistance." So what we get here, instead of the usual survey of wars, presidents, and institutions, is a survey of the usual rebellions, strikes, and protest movements. Zinn starts out by depicting the arrival of Columbus in North America from the standpoint of the Indians (which amounts to their standpoint as constructed from the observations of the Europeans); and, after easily establishing the cultural disharmony that ensued, he goes on to the importation of slaves into the colonies. Add the laborers and indentured servants that followed, plus women and later immigrants, and you have Zinn's amorphous constituency. To hear Zinn tell it, all anyone did in America at any time was to oppress or be oppressed; and so he obscures as much as his hated mainstream historical foes do—only in Zinn's case there is that absurd presumption that virtually everything that came to pass was the work of ruling-class planning: this amounts to one great indictment for conspiracy. Despite surface similarities, this is not a social history, since we get no sense of the fabric of life. Instead of negating the one-sided histories he detests, Zinn has merely reversed the image; the distortion remains.
