When Belligerent Baboons Die, The Troop Turns Harmonious For Decades

A very strong argument for a widespread committee for aesthetic deletions action on all neo-cons.

The victims were all dominant adult males that had been strong and snarly enough to fight with a neighboring baboon troop over the spoils at a tourist lodge garbage dump, and were exposed there to meat tainted with bovine tuberculosis, which soon killed them. Left behind in the troop, designated the Forest Troop, were the 50 percent of males that had been too subordinate to try dump brawling, as well as all the females and their young. With that change in demographics came a cultural swing toward pacifism, a relaxing of the usually parlous [- perilous, precarious] baboon hierarchy, and a willingness to use affection and mutual grooming rather than threats, swipes and bites to foster a patriotic spirit.

Remarkably, the Forest Troop has maintained its genial style over two decades, even though the male survivors of the epidemic have since died or disappeared and been replaced by males from the outside. (As is the case for most primates, baboon females spend their lives in their natal home, while the males leave at puberty to seek their fortunes elsewhere.) The persistence of communal comity suggests that the resident baboons must somehow be instructing the immigrants in the unusual customs of the tribe.

"We don't yet understand the mechanism of transmittal," said Dr. Robert M. Sapolsky, a professor of biology and neurology at Stanford, "but the jerky new guys are obviously learning, 'We don't do things like that around here.' "

The report also offers real-world proof of a principle first demonstrated in captive populations of monkeys: that with the right upbringing, diplomacy is infectious. Dr. Frans B. M. de Waal, the director of the Living Links Center at the Yerkes National Primate Research Center of Emory University in Atlanta, has shown that if the normally pugilistic rhesus monkeys are reared with the more conciliatory stumptailed monkeys, the rhesus monkeys learn the value of tolerance, peacemaking and mutual hip-hugging.

Dr. de Waal, who wrote an essay to accompany the new baboon study, said in a telephone interview, "The good news for humans is that it looks like peaceful conditions, once established, can be maintained," he said.

"And if baboons can do it," he said, "why not us? The bad news is that you might have to first knock out all the most aggressive males to get there."
