[ED. NOTE: The following interview with Harvard biological anthropologist Richard Wrangham was originally published eight years ago on Edge, on February 28, 2001. Given the media interest attending the publication of Wrangham's related book, Catching Fire: How Cooking Made Us Human, we are bringing the piece back for an encore.]
One of the great thrusts of behavioral biology for the last three or four decades has been that if you change the conditions that an animal is in, then you change the kind of behavior that is elicited. What the genetic control of behavior means is not that instincts inevitably pop out regardless of circumstances; instead, it is that we are created with a series of emotions that are appropriate for a range of circumstances. The particular set of emotions that pop out will vary within species, but they will also vary with context, and once you know them better, then you can arrange the context.... It's much better to anticipate these things, recognize the problem, and design in advance to protect.
Introduction
According to Harvard biological anthropologist Richard Wrangham, almost two million years ago humans emerged from a stock of pre-human apes. Remarkably, our species is still evolving today, faster than ever. "Why we evolved then, and why we are still changing, are problems that shape our souls," he says.
Wrangham believes that humanity was launched by an ape learning to cook. In a burst of evolution around two million years ago, our species developed the family relations that make us such a peculiar kind of animal. Cooking made us women, men and lovers.
"We behave like our two closest relatives," Wrangham says. "Chimpanzees and bonobos, because in spite of first appearances, we face somewhat similar kinds of problems to each of those species. Cooking makes our behavior partly chimpanzee-like because it intensifies a chimpanzee-like division of labor. Self-domestication, on the other hand, makes us bonobo-like by selecting for a youthful psyche. In both cases human behavior echoes the biology of our cousins, though never exactly copying it."
One of Wrangham's central ideas is that we should cherish the parallels between humans and other great apes, because they help us to understand our own behavior. "For all our self consciousness, we humans continue to follow biological rules. Life is easier if we understand those rules. Recognition of the deep contradictions in humanity binds us to our past, and also lights our future."
Other themes to his thinking: "We still have much to learn; We should not be afraid of biology; Dichotomous thinking (e.g. biology vs. culture; women vs. men) is almost always unhelpful "Evolutionary anthropology has excessively neglected females."

RICHARD WRANGHAM is a professor of biology and anthropology at Harvard University who studies chimpanzees, and their behavior, in Uganda. His main interest is in the question of human evolution from a behavioral perspective. He is the author, with Dale Peterson, of Demonic Males: Apes, and the Origins Of Human Violence, and Catching Fire: How Cooking Made Us Human.
