It is always slightly amusing to read these articles of researchers discovering we're not the only intelligent species on earth, that insects can learn, that other mammals can transmit knowledge, use tools etc. I have learned a lot from watching my chickens, my dog and my cats - they self medicate with specific plants (for example, chewing Tansy[1] leaves, which is a powerful medicine, or any of the myriad other wild herbs growing in our garden), and they learn from each other which plants are the interesting ones. I don't know that this behavior has an intellectual, cerebral aspect, but it's certainly there. [1] https://en.wikipedia.org/wiki/Tansy https://en.wikipedia.org/wiki/Tansy
