Wild elephants can discern the languages humans are speaking, such as the those of the Masai group in Kenya (who occasionally kill elephants) and Kamba group (who don't pose as much of a threat). When scientists played recordings of Masai men speaking, elephant herds were about twice as likely to retreat than if they heard the voices of Kamba men.

Elephants show cooperation, according to an experiment by researchers in Thailand. In the study, elephants figured out how to work as a team to lower a platform holding food. Two elephants had to tug on the ends of a rope simultaneously -- if only one elephant pulled on the rope, the cord unthreaded from the platform and the treat remained out of reach.
