The world鈥檚 largest study of chimpanzee behaviour has come to the rather negative conclusion that interactions with humans decrease the range of chimpanzee behaviours and may interfere with the way in which chimp parents pass skills to their offspring.
Chimps learn skills from swimming to digging for insects with sticks and exhibit a wide range of vocal communications. In environments where they may be living near humans such skills or behaviours are displayed less and may be replaced altogether with more human related activities such as raiding crops or rubbish dumps.
