Elephants recognize each other after years apart,and even seem to mourn their dead.Bees communicate using a special waggle dance to indicate the location and quality of a food source to other bees.Chimpanzees engage in complex deception schemes,suggesting not only do they think,but they understand that others do, too.And then there is Alex the Grey Parrot,who could use human language to distinguish the colors and shapes of absent objects,and even understand abstract concepts,like bigger and smaller.That sounds a lot like intelligence,and not just the work of mindless machines.
