Notes from Two Scientific Psychologists: Did language emerge from the neural systems supporting aimed throwing? | Psychology and Brain News | Scoop.it

Aimed throwing is surprisingly uncommon in the animal kingdom. Humans do it par excellence, and otherwise it only shows up occasionally, even in our closest relatives. Chimpanzees will throw things (often faeces) but unlike humans don't throw things when hunting or trying to get food; when non-human animals throw things, it's usually part of a social encounter.
