"Girls are often considered to mature faster than boys. The same appears to be true among chimpanzees, according to new research to be published in the journal Animal Behavior [0]. Elizabeth Lonsdorf of Lincoln Park Zoo, Chicago, observed young chimps in Gombe National Park, Tanzania, along with their mothers over a period of four years. She found young female chimps tended to watch intently as their mothers fished termites out of earthen nest mounds using sticks. As a result, young females mastered the technique at about a year and a half old. Males, on the other hand, paid little attention to the finer points of termite fishing. As a result, they needed about two years longer to acquire this skill. The findings are supported by Lonsdorf's preliminary research on captive chimps at the zoo.
