Lie - in Other Species

In Other Species

The capacity to lie has also been claimed to be possessed by non-humans in language studies with great apes. Even Koko, the gorilla made famous for learning American Sign Language has been caught red-handed. After tearing a steel sink from the wall in the middle of a tantrum, she signed to her handlers that a cat did it, while she pointed to her kitten. It is unclear if this was a joke or a genuine attempt at blaming her tiny pet. Deceptive body language, such as feints that mislead as to the intended direction of attack or flight, is observed in many species including wolves. A mother bird deceives when it pretends to have a broken wing to divert the attention of a perceived predator—including unwitting humans—from the eggs in its nest to itself, most notably the killdeer.
