While that's well known 2 people, it's a bit of a surprise for non-human primates. But a report 3 Monday's online edition of Proceedings of the National Academy of Sciences 4 that female baboons in Kenya raised in groups with their fathers matured 5 and had a longer reproductive life than other baboons. Males had not 6 thought to be engaged in a level of care that would make 7 difference to their offspring, said Susan Alberts, an associate professor of biology 8 Duke University. Alberts and colleagues studied groups of yellow baboons 9 near Kenya's Mt. Kilimanjaro. In these groups both males and females have several partners. 10 presence of the father in a group gave the daughters a jump-start 11 sexual maturity, a measure of fitness, the researchers said. "For young females, 12 their major opponents in life are adult females and fellow juveniles, the 13 of any adult male may be helpful," Alberts said in a statement. 14 do not share food after their mothers cease nursing, but the father's 15 during early maturity may still help daughters get more to eat if 16 father reduces any harassment of their offspring. "Sons also experienced accelerated maturation 17 their father was present during their immature period, but only if their 18 was high-ranking at the time of their birth," the researchers found. For 19 , the major competition for food is other males, so only the presence 20 a high-ranking father would help, the researchers said. The research was funded by the National Science Foundation and a Marie Curie Outgoing Fellowship.
