How Baboons Think

Dorothy Cheney and Robert Seyfarth, a husband-and-wife team of biologists at the University of Pennsylvania, have spent 14 years observing the Moremi baboons. Through ingenious playback experiments performed by themselves and colleagues, the researchers say they have worked out many aspects of what baboons use their minds for, along with their limitations. Reading a baboon’s mind affords an excellent grasp of the dynamics of baboon society. But more than that, it bears on the evolution of the human mind and the nature of human existence. Dr. Cheney and Dr. Seyfarth have summed up their new cycle of research in a book titled “Baboon Metaphysics.” Their conclusion, based on many painstaking experiments, is that baboons’ minds are specialized for social interaction, for understanding the structure of their complex society and for navigating their way within it. “Monkey society is governed by the same two general rules that governed the behavior of women in so many 19th-century novels,” Dr. Cheney and Dr. Seyfarth write. “Stay loyal to your relatives (though perhaps at a distance, if they are an impediment), but also try to ingratiate yourself with the members of high-ranking families.” NY Times
