The Most Surprisingly Smart Animals

Many believe that cats are much smarter than dogs. And who of the animals can communicate in sign language? And are the sheep really stupid?

The criterion is Encephalization quotient (stands beside in brackets next to each animal name).

This scientific term is intended to approximately characterize the development of the intelligence of the animal.

The index of encephalization is used to identify trends in development, as well as the potential of various species.

Sheep (0.7)

In the 10 place – a sheep! The animal was domesticated about 8,000 years ago in the Middle East. The sheep does not show high intelligence, and it will not work with her. A clear outsider.

Horse (0,8)

The horses are well developed memory. Also in these animals, conditioned reflexes are perfectly developed and fixed. This is the basis for the practical use of horses.

Cat (0.9)

Some researchers believe that the intelligence of cats is close to the intelligence of two-year-old children. Cats are able to adopt some behavior of the owners and adapt to it.

Squirrel (1.0)

Squirrels settled comfortably between cats and dogs. Thanks to their intelligence, they learned to survive well in the wild. Researchers have found that brave ears for the winter even dried mushrooms.

Squirrels are the real gurus in the field of keeping stocks for the winter. Do not know how to save nuts? Share them with proteins. Not the fact that they will return, but they will keep it for sure.

Dog (1,2)

Psychological researchers Elliston Reid and John Pilley of the College of Woughford in Spartanburg were able to train a border collie named Chaser to verbal perception of more than 1,000 objects.

The dog also knows how to classify the functions and shapes of objects, which is comparable to the intellectual abilities of a three-year-old child.

African Elephant (1.4)

The brain of an African elephant weighs about 5 kg. This is a record. The brain has a whale less than an elephant! Scientists believe that elephants can experience grief, joy, compassion; developed cooperation, self-awareness, as well as playfulness.

Studies have shown that elephants excel people in tracking several objects in space. Already collected enough data demonstrating the altruism of elephants in relation to other species, for example, rescuing dogs.

These massive giants observe funeral rituals, revering dead relatives.

Gorilla (1.6)

The intellect of gorillas is an order of magnitude lower than that of chimpanzees. But the gorillas developed a primitive communication, which is based on 16 sound combinations. Some gorillas have learned the language of gestures.

Pygmy marmoset (1,8)

This animal lives in the forests of the Amazon. Pygmy marmoset are quite often found and are not under threat of extinction. The ratio of the volume of the brain to the body of the primate is one of the largest.

Chimpanzee (2.2)

Chimpanzees learned to communicate in sign language. They are able to use words in a figurative sense, they can create new concepts.

A distinctive feature of the chimpanzee is the presence of a sense of humor. These monkeys actively use tools, and also recognize themselves in the mirror. In addition to using tools, chimpanzees have learned to create primitive tools.

For example, they make special sticks for catching ants.

Dolphin (5.2)

And now a surprise: it turns out that the human encephalization coefficient is 7.6. Not so far people left the dolphins. What can a dolphin do? Much.

The dolphin learned to correlate the image of his body with the structure of the human body, using analogies. Can understand new sequences in an artificial language.

Is able to generalize rules and build abstract concepts. Disassembles symbols for different parts of the body. Understands index gestures. Recognizes himself in the mirror.
