Young children invent tools, just like great apes
Children spontaneously invent tools, they don't just learn to use them
In an experiment based on 12 known types of tool use by chimps and orangutans, 50 children, between the ages of 2 and 3 1/2, were challenged to solve simple problems - such as retrieving a sticker from a box using a stick - without any prior instruction.
Most of the children successfully completed their tasks in a matter of minutes, by using a previously unknown tool. The study concludes that spontaneous tool use in humans begins much earlier than previously thought.
