Newest ethologists view Elephants as among the world's most intelligent animals. With a mass of approximately 5 kg (11 lb), elephant brains have an overabundance of mass compared to those of any other land animal, and although the largest whales have body masses twenty-fold that relating to a normal elephant, whale brains are barely twice the mass of an elephant's brain. Moreover, elephants have a total of 300 billion neurons. Elephant brains are like humans' with regards to general connectivity and areas. The elephant cortex has numerous neurons being a human brain, suggesting convergent evolution.
Elephants manifest a multitude of behaviors, including those associated with grief, learning, mimicry, play, altruism, using tools, compassion, cooperation, self-awareness, memory, and communication. Further, evidence suggests elephants may understand pointing: a chance to nonverbally communicate an item by extending a finger, or equivalent. Such behaviors advise that elephants are highly intelligent; it is thought they're equal with cetaceans and primates in this connection. On account 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 original Greek philosopher, Aristotle, once declared that the elephant was "the animal which surpasses all the others in wit and mind."
However, a few elephant researches, plus some ethologists, indicate experimental and anecdotal evidence which seem to contradict the scene that elephants are self-aware, can think, and possess a theory of mind.
