A new study of young chimpanzees may risky behaviour in children. The study is from researchers at the University of Michigan in the USA. They over 100 wild chimpanzees in a national park in Uganda. The chimps ranged in age from 2 to 65 years. The researchers at how the animals swung through trees. The youngest chimps to do more dangerous things, like go of branches and letting themselves fall. Older chimps fewer risks and made sure they branches firmly.
