Elephant from Smartest Animals in The World

Elephants first appeared in Africa about 23 million years ago. At that time dominant herbivores were horses. Through centuries, elephants have evolved into extremely large herbivores, which was the consequence of their struggle with horses for the same food. They are famous for their ability to use various tools in nature, while they are obedient quick – learners in captivity. Elephants have more brain cells per square centimeter than any other species of animals, which explains their capability to learn and remember. They are also very curious and well-behaved, they clean their food before eating it. What sets them apart from other animals is their compassion and concern towards their own, and other species, and this indicates well-developed intelligence.
