Scientists have arranged such here competition between house pupils

The winner is found. Whether will put it the end to disputes on the superiority of one over others?

And conducting scientific yes zoopsychologists undertook to judge dumb animals on 11 nominations.

ROUND 1. THE BRAIN

At a dog the brain weighs 64 grams. At a cat - 25 grams. But after all and the usual dog is much heavier than a cat. And to define mind on weight of a brain concerning weight of a body it is incorrect. The quantity of the neurons participating in processing of the information is important. In this sense of a cat do dogs with the devastating account. At cats - 300 million neurons. At dogs only 160 million.

As we considered: the Points earned by cats... 1-0... And dogs

ROUND 2. WHO EARLIER?

Researchers have compared DNA of dogs and gray wolves as the most their close relatives, to try to define precisely time of their domestication. In 1997 scientists under the direction of Robert Wayne at University of California, Los Angeles, have considered that gray wolves, close relatives of dogs, have been cultivated 135 000 years ago. But the new version has been then put forward: the pier, it happens at least 50 000 years ago. Other researchers believe that the domestication has occurred even later - approximately 16 thousand years ago.

When have tamed cats, too up to the end it is not clear. Drawings on ancient Egyptian tombs specify that cats were popular in houses at least for 3 thousand years B.C. Still the scientific assume that cats have come to people at once as soon as there was an agriculture. Because there where grain is stored, mice are got. And where mice, there and cats. In 2007 have compared DNA of cats in all territories where there was a first agriculture, and have found out that at least 9500 years ago cats already were the best friends of people. It proves to be true also that пушистиков buried together with owners. The earliest skeleton of a kitten near to a skeleton of the person has been found out in Cyprus.

1-1

ROUND 3. LOVE TO THE OWNER

Zoopsychologists assimilate communication of the pupil and his owner with relations between the parent and the child. When the father-mum nearby, the kid is happy and bravely investigates all around. When the parent nearby isn't present, becomes unfortunate, is beaten to the first comer to the stranger.

- The tested dogs have shown such behavior. And here cats, - Adam Miklozi from University in Budapest speaks, - such haven't shown.

And remains secret, how much strongly cats are adhered to the owner. It is known only that they don't like to leave a habitual residence. They are more independent, than dogs, and in general at heart singles. And here dogs are more inclined to life with people. Zoopsychologists have found out that if to a 4-month's puppy to give a choice - the person or a dog in partners the puppy with большей probability will choose the first.

1-2

ROUND 4. POPULARITY AT PEOPLE

Experts have counted up, whom people prefer to hold houses is more often. Here again cats have come out winners with huge overweight. It is impossible to spend exact census of all house pupils in the world, the livestock пушистиков in the EU countries therefore has been approximately estimated. Calculations are that: on 204 million cats only 173 million dogs.

2-2

ROUND 5. INTELLIGENCE

Dogs of breed of a collie in a condition to understand more than 200 words. But even representatives of breeds with smaller abilities can answer set of commands, and they distinguish not only words, but also human gestures, a ducking, a mimicry. Dogs also hold visual contact to people. They in general seem more located to to mutual understanding with the person. Cats are less obedient and are motivated on that so to aspire to understand the person. If it is a question of food dogs aspire to deserve it. And her cats will demand, if till now couldn't find.

2-3

ROUND 6. THE DECISION OF PROBLEMS

Neither cats, nor a dog haven't passed the majority of tests for the decision of problems with food search. That scientists wanted, that animal fur-trees food slices in a certain order, but they stupidly absorbed all successively. That tried to teach to define the hidden food on special markers. Cats and dogs didn't react to labels. The cleverest wolves, cousins of dogs who learned have shown themselves to open a door, only once having observed, as it was made by other wolf. Dogs could look many years behind how someone opens a door, but and not to learn it to do independently.

But all the same this round is won by dogs for the reason that they can be guides for blind. And cats you will not force it to do.

2-4

ROUND 7. THE VOCAL

Dogs bark, cats mew, using "voice" for interaction with people. However, the vocal repertoire of cats is rather limited in comparison with dogs, at which more than vocal flexibility. Obviously, to it promoted life among people and necessity to communicate with the owners. After all wolves only bark and howl, more than any sounds.

But all the same cats have found one sound cunning for which them award cream and caress more. They catch people on silent singing-purring which cherishes our hearing. At subconscious level he is perceived by people as a frequency range of sounds of the child. And in it cats are ingenious. For what with shine win this round.

3-4

ROUND 8. TRAINING
Dog

Dogs are easier trained, than other animals. The chimpanzee and dolphins study emulation, that is observe of the person and try to repeat the same. And dogs - as human babies, through pedagogical manual. They react to remarks, visual contact, gestures, a voice.

To cats it is far to results of dogs. Him as though all the same. And dogs really want to make that ask them. They with a great interest and more seriously concern the person.

Besides, to dogs as the group of researchers of University of Colorado has found out, it is possible to impart ethical standards. That is they can be well brought up unlike cats.

3-5

ROUND 9. SUPERFEELINGS

Sight, sense of smell and hearing - the most important feelings for both kinds. People have deduced infinite quantity of breeds of dog to use with benefit their talents. And it is logical to expect that at them they will be is better developed, than at cats. The nose of a police dog, for example, contains 300 million receptors of a smell in comparison with 5 million at people. At cats on the average 200 million receptors of a smell. But cats perfectly see in the dark (six times better, than the person, and dogs "only" in five). The acoustical range мурзиков is much wider, than at dogs, he is stretched from 45 to 64 000 hertz (бобики perceive a sound only to 45 000 hertz).

4-5

ROUND 10. INFLUENCE ON THE NATURE

Only in Great Britain cats kill more than 180 million wild animals every year - birds, small rodents. But dogs concede to them a little. Because of them population of a rare European goatsucker is strongly lowered, they ruin nests, and even their presence at the nature is capable to reduce a biodiversity. And they not only eat, but also spoil. Scientists have calculated, how many a place it is necessary for a dog and how many a cat. Also named these calculations «ecological trace». The area of the earth about 0,84 hectares annually is required to a dog of the average size. Even to such crumb as a chihuahua, 0,28 hectares are necessary. And here it is necessary for a cat only 0,15 hectares. They are scientists believe virtue.

ROUND 11. ADVANTAGE

Dogs can hunt, graze and protect herds. They will smell drugs or a bomb in luggage. Serve as guides of the blind. Participate in sports races, pull sledge, help children to study and sometimes even are capable to predict earthquakes. Cats are good only that exterminate rodents.

- Probably, this estimation is unfair! - scientists speak. - eventually we love house pupils for other reasons. Cats are beautiful and soft, and their stroking as show researches, reduces pressure and even treats. Though dogs too remove stress. Can lower a blood pressure and cholesterol level. Therefore British magazine «health Psychology» named dogs much more useful to health.

5-6

TOTAL: with the minimum advantage have won dogs. But it is all - scientific calculations. And for someone there is no more lovely a favourite purring creation. Well and scientists start up get to itself whom want.
