Elephants imitate sounds as a form of social communication
Elephants learn to imitate
sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for mainta...
Autism linked to mirror neuron dysfunction
...rocesses language, for instance, or being able to imitate
