More than a hundred years ago, Darwin not without surprise, said: "the Brain in all domesticated rabbits in comparison with the brain of a wild rabbit, reduced in size..." But what is it with cats? Here's the answer: conclusion Darsky was universal, it applies to all domestic animals, whether it be rabbits, donkeys or camels.
However, that the brain of the domestic cat "lost", to speak shunned - it easily escape and will mingle with their uncivilized brethren. In 1972 Professor C. Geptner and E. Matyushkin was measured head Leningrad, wild forest and steppe cats and domestic cats, the remains of which were found during the excavations in Novgorod. It was found that in XIII-XIV centuries Novgorod roofs howled Hilo create. To the XIX and the XX century these four-legged was corroded, pokrupney. But gray matter have not increased absolute and relative size of the cerebral capsule more than half a Millennium did not rise. Even the skinny ragged forest cat by volume of the brain will give odds glossy apartment cat. Even the wild steppe cat, "brain" more than at home purring, although the way of life they live is not very different (between brain volume and complexity of motor functions have a direct link).
And not it is noteworthy that this "intellectual" difference does not depend on life experience: the difference in brain volume appears, barely kittens begin to change the milk teeth.
And another, as they say in science, domestication sign. We are talking about the indentation of Swaggy - hole, where the cat's nose meets the forehead. This hollow can be found on the muzzles almost all home and half wild cats, and the forest it is rare, and the hollow they have shallow, barely noticeable. Expressed the opinion that this hole also demonstrates the degradation of domestic cats as predators.
