What is a chimpanzee thinking?
Shares ninety-eight percent of your DNA. Spends it entirely differently.
Chimps make and carry tools - stripped twigs for termites, stones as hammers - and different communities use different techniques passed down socially, which is culture in the technical sense.
They also beat us at one thing outright. In a numerical memory task where digits flash on a screen for a fraction of a second, young chimps recall the positions more accurately than adult humans do.
