Most contemporary ethologists view Elephants as among the world's most intelligent animals. Having a mass of more than 5 kg (11 lb), elephant brains have more mass than others of any other land animal, and even though the biggest whales have body masses twenty-fold the ones from a normal elephant, whale brains are barely twice the mass of the elephant's brain. Additionally, elephants possess a total of 300 billion neurons. Elephant brains act like humans' regarding general connectivity and areas. The elephant cortex has as much neurons like a mind, suggesting convergent evolution.
Elephants manifest a multitude of behaviors, including those connected with grief, learning, mimicry, play, altruism, use of tools, compassion, cooperation, self-awareness, memory, and communication. Further, evidence suggests elephants may understand pointing: the ability to nonverbally communicate a physical object by extending a finger, or equivalent. Such behaviors declare that elephants are highly intelligent; it can be thought they're equal with cetaceans and primates in connection with this. As a result of such claims of high intelligence and due to strong family ties of elephants, some researchers argue it is morally wrong for humans to cull them.The standard Greek philosopher, Aristotle, once asserted the elephant was "the animal which surpasses others in wit and mind."
However, several elephant researches, and a few ethologists, point to experimental and anecdotal evidence which apparently contradict the vista that elephants are self-aware, can think, and still have a theory of mind.
