Article from Telegraph.co.uk:
"A laboratory experiment trained Diana monkeys to insert a token into a slot to obtain food.
A male who had grown to be adept at the task was found to be helping the oldest female who had not been able to learn how to insert the token.
On three occasions the male monkey picked up tokens she dropped and inserted them into the slot and allowed her to have the food."
