Intelligence in the animal world

Although humans are the only species that can make fire, communicate through letters and notes, can read a map and can count, our brains do not differ much from those of monkeys and other mammals.

The two biggest differences are that we have more nerve cells in our pleated cerebral cortex than animals, and that our nerve cells are surrounded by a thicker layer of insulation, so that the nerve signals can run faster.

That is why most researchers think that our intelligence is not essentially different from that of animals, but that we have only developed it to a higher level.

Many animals have intelligent traits: they use tools, work together, communicate or take care of peers, but humans do all this to a much higher degree.

However, animal intelligence is difficult to measure because they cannot tell us what they think, so we have to guess what the most intelligent animals are.

Primates

Chimpanzees are as intelligent as a child of three, because they can express themselves with sounds, facial expressions and gestures, manipulate and invent snares to benefit from it and understand the order and size of numbers.

Marine mammals

Dolphins, such as the bottlenose dolphin, can learn complex tricks, perform them synchronously with other dolphins and pass them on to other species. They can also learn to understand simple artificial languages ​​and express themselves in them.

Mammals

The Indian elephant can make simple additions: if you have two baskets with 3 and 5 apples respectively (and the elephant can look in the baskets), and then put 2 extra apples in each basket, the elephant will go to the basket with 7 apples walk.

Birds

The seesaw crow uses all kinds of tools in the hunt for food. For example, he sometimes throws nuts on a traffic road, so that cars drive over it and the hard caps crack.

Invertebrates

The veined octopus or coconut octopus turns two half coconuts into a house, where it hides itself when there is a danger.

Fish

The cleaning slip fish does its extra best to rid a fish of parasites if other fish are watching, which may therefore also want to make use of its service.

Brains of prehistoric monkey were ready to grow

More than 3.6 million years ago a southern monkey lived in present-day South Africa. Just like us, she walked upright, on two legs, and was one of the earliest known branches of our family tree, the so-called Australopithecus. Researchers baptized her 'Little Foot', and now they have gained insight into her brain thanks to scans of the inside of the skull.

Mammoet collapsed genetically

He is known as a big, proud giant from prehistoric times with meters long tusks and a thick fur that could withstand the lowest temperatures. There are, however, indications that our image of the woolly mammoth, which was still roaming the earth just 4,000 years ago, is incorrect. At least not from his last years of life.

Mammoths must save the Arctic

Several research teams are currently working to revive the mammoth by cloning or genetically modifying it. And if it is possible to bring the mammoths back to life, then the Russian geophysicist Sergey Zimov has a plan with the giant beasts. They have to save the Arctic by slashing the ground.
