56-year-old chimpanzee gives birth
A 56-year-old chimpanzee has surprised officials at a zoo in north-east Kansas by giving birth.
Officials at Sunset Zoo in Manhattan announced that Suzie the chimp gave birth to a female on August 18 and that the mother and baby are in good health.
Zoo director Scott Shoemaker said Suzie was taken off birth control because of medical concerns - and because zoo officials didn't think she would get pregnant at her age.
Zoo curator Mark Ryan said he hasn't heard of any older chimpanzee who has given birth anywhere in the country.
Chimpanzees in captivity usually live to about 60 years of age.
