How would we feel amused by the idea that people much smarter than animals, we’re still very much in common. For example, some animals like us are able to sacrifice themselves for the sake of their relatives. Moreover, many monkeys know how to use tools for hunting and eating food — they really like us! A couple of years ago, French scientists noticed that one of the rare species of pigs, too, has intelligence and uses the bark of trees as shovels for digging. These notches are then used for breeding.
Pigs that are able to use tools, are in the form of warty (Sus cebifrons). At the moment they are on the verge of extinction, so a family of male, female and two daughters, lives in the zoo of the Botanical garden in Paris. In 2015, the researchers, led by ecologist Meredith root-Bernstein noticed that a pregnant female has started to dig to build a nest with the snout, and then took in a mouth a small piece of bark and continued to dig the earth with it.
As far as pigs are intelligent animals?
The researchers continued to monitor the pigs and in the following years and tossed them pieces of bark and sticks. Time from time, all four pigs were really armed them and began to dig. However, scientists noticed that with the help of the snout pigs build nests much faster than using tools. To answer why they use such awkward methods of digging, scientists still can’t, but they do have one assumption.
As warty pigs are a critically endangered species and mostly live under the protection of the people, the scientists had virtually no opportunity to observe their behavior in nature. Perhaps living on the freedom of individuals do not know how to use the tools, and observed in zoos pigs learned an unusual skill have individuals from other zoos. Anyway, the fact that pigs can learn to use the tools is a scientifically proven fact.
Did you know that in China grow swine the size of a polar bear?
What animals use tools?
That animals are able to use tools, is not surprising. For example, people always know that elephants can clasp a trunk of a stick and scratching their back. They can also take a branch with leaves to fan it to deter flies and other insects. Anyway, everyone must have seen the online video where the elephants paint pictures using paint and brushes. You still have doubts about the mental abilities of animals?
Developed mental abilities, possess even insects. Anyone would be hard to believe, but tools are even tiny ants. For example, living in the southern United States leaf-cutter ants cut leaves and use them as containers for the transport of food and water. Also this kind of volume of interesting ant colonies — they can be millions of ants, the total weight of which is sometimes equal to the weight of adult cows. And the cows, by the way, can weigh more than 600 pounds.
As you can see, animals are still able to surprise us with his intelligence. If you are interested in this topic, from myself I recommend to read our material about the strongest animals in the world. Do you know what bird has the most developed muscles? I didn’t know.
