The mammals presented in the nature more than 4 thousand by types differ from each other in the body weight, forms, dwelling conditions. The class of mammals is considered the cleverest among the animals inhabiting the planet. In their numerous families meet such at which mental abilities are developed very strongly.
Monkeys
The family of primacies where it is necessary to carry gorillas, a chimpanzee, monkeys, orangutans, baboons, gibbons, by right heads the list of the cleverest mammals. It is not casual, the person – the most reasonable being on the Globe also treats this group.
According to the biologist Edward Wilson, on development of intelligence first place among primacies is won by chimpanzees. They very much resemble people the habits, "traits of character". Chimpanzees have fine memory. They can show human qualities: ability to empathize and help others, to show feelings of joy and anger.
At primacies cerebral hemispheres are well developed, rather quite good language skills promoting communication with individuals of the look are peculiar to them. Monkeys are wonderful parents and tutors: very much make thrifty use of the cubs, train them in all known skills. They are capable to transfer perfectly each other different information. Instruments of labor are necessary not only to people, but also monkeys: these animals quite often use them, for example, in the course of getting of food.
Dolphins
People learned about surprising abilities of dolphins in the middle of the twentieth century when these mammals began to be studied and accustomed to training comprehensively. Dolphins, as well as at people, have a social life, mother female within several years teaches the cubs to rules of existence in dolphin "state". These mammals have very difficult language which people try to solve. As show experiments, typically human line – consciousness is peculiar to dolphins. High I.Q. of dolphins-afalin was observed by scientists in the Pacific Ocean. In search of food these animals showed really human invention: before overturning stones on a seabed, they wrapped the gentle nose in a sea sponge. The nature allocated a brain of dolphins with the most unique property: cerebral hemispheres sleep in turn as it should be responsible constantly for breath, forcing an animal to emerge from time to time on a water surface at night.
Dogs
The devoted friend of the person – the dog, began to serve truly people 10 thousand years ago, always is nearby and any minute is ready to come to the rescue of the owner. But dogs - also very clever pets. They perfectly understand many words of people and their gestures, easily give in to training. For example, dogs it is possible to teach to make the simplest mathematical operations, to distinguish images in photos. Among representatives of a large number of breeds of dog carry poodles to number of the cleverest.
Pigs
Intellectual level of pigs is comparable to mental capacities of dogs and cats, and in something can even surpass them. For example, as a result of the experiment made by scientists which assumed training of pigs in movement of the cursor at the screen of a pig chimpanzees coped with the task put before them not worse. These pets live on a certain daily routine, very well feeling time of day. They worry in several minutes before feeding, and derogation from an established order for a short time can cause in them negative reaction. Therefore the academician I. Pavlov marked out a pig as the most "nervous" animal.
The most obedient animal
The one who considers silly animals of domestic sheep is mistaken. The erudite zoologists investigating them proved the return: sheep clever and bright and the intelligence concede to cats and dogs only a little. These animals are capable to distinguish geometrical figures and colors, have excellent memory. Sheep without effort select feeding troughs with a forage according to their color, quickly distinguishing from empty. Once the acquired information is stored in memory of sheep about three years. They know well in the grazed dense flock of the fellows whom sometimes the shepherd hardly can distinguish. Sheep - not the silliest, and obedient animals.
