Every year, many species make the journey from one place to another, following the same paths and ending up in the same places. Every year since boyhood, the acclaimed scientist and author Bernd Heinrich has done the same, returning to a beloved patch of western Maine woods. Which led him to wonder: what is the biology in humans of this primal pull toward a particular place, and how is it related to animal homing? In The Homing Instinct, Heinrich explores the fascinating mysteries of animal migration: how geese imprint true visual landscape memory; how scent trails are used by many creatures to locate their homes with pinpoint accuracy; and how even the tiniest of songbirds are equipped for solar and magnetic orienteering over vast distances. And he reminds us that to discount our human emotions toward home is to ignore biology itself.
“A graceful blend of science and memoir . . . [Heinrich’s] ability to linger and simply be there for the moment when, for instance, an elderly spider descends from a silken strand to take the insect he offers her is the heart of his appeal.” — Julie Zickefoose, Wall Street Journal
“Deep and insightful writing.” — David Gessner, Washington Post
A revelatory look at why we dehumanize each other, with stunning examples from world history as well as today's headlines
"Brute." "Cockroach." "Lice." "Vermin." "Dog." "Beast." These and other monikers are constantly in use to refer to other humans—for political, religious, ethnic, or sexist reasons. Human beings have a tendency to regard members of their own kind as less than human. This tendency has made atrocities like the Holocaust, the genocide in Rwanda, and the slave trade possible, and yet we still find it in phenomena such as xenophobia, homophobia, military propaganda, and racism. Less Than Human draws on a rich mix of history, psychology, biology, anthropology and philosophy to document the pervasiveness of dehumanization, describe its forms, and explain why we so often resort to it.
David Livingstone Smith posits that this behavior is rooted in human nature, but gives us hope in also stating that biological traits are malleable, showing us that change is possible. Less Than Human is a chilling indictment of our nature, and is as timely as it is relevant.

In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.
An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.
