Chimpanzees and the dog, which is more like a glance mankind?, chimpanzees of flat face than a dog's long face more amiable.

If you consider the chimpanzee and human gene on over 95% of similarity, I would be happy to talk to Primate purpose chimpanzees not bark of Carnivora animals always fraternizing. However, prior to this invocation of a media Germany weekly news the dog than Gorilla more like humans. (However, the emergence of chimpanzees in the text without any regard to the description of the Gorilla, so the title should be "dog than chimpanzees more like humans," the translator is obviously do not know the difference between the gorilla and chimpanzee. ）

Dog smarter than chimpanzees?

I found the source of the news, an article entitled "behavioral science steering dogs looking for answers.

In this article, the author describes the evolution of the Max Planck Institute, Germany and the anthropological Institute of card-Zaton (JulianeKaminski) on the dog for a series of experiments. Card-Zaton has found that a dog has a remarkable ability to understand abstract language, for example, most notably — understanding human gesture and eyes.

In an experiment in front of the dog and chimpanzees are put on an empty box and a pretended food box.

When a laboratory technician fingers point to a box, the dogs will immediately understand that this is the prompt it there is food, walk past. And our close relatives of the chimpanzee, you silly stared laboratory personnel fingers, not so. When the laboratory personnel do not see the box but walls, dogs and even understand that this is not allowed to go to the box to find food, so he obediently, in contrast, chimpanzees students regardless of this, own's in the box to turn down. As a result of participation in experimentsof dogs but just weaned, did not have the human training, researchers believe that this understanding abstract language and the ability to communicate with people, seems to be portrayed in the genes in the dog.

From Wolf to dogs

A dog is man's earliest domestication of animals.

Kunming Institute of Zoology, Chinese Academy of Sciences of the chimerical has participated in a study of the origin and evolution of dog international cooperation projects, the world's scientists are collecting the local variety of breeds of dog and Wolf of gene analysis, ultimately to speculate that the dog is 15000 years ago by the East Asian human domestication from wolves. Another world over 400 varieties of dog genome comparison results show that originated in East Asia's hot dogs, dog, Akita and chaiquan is the most ancient breeds, the results of the study with Zhang yaping.

Although compact Kit dolls to mellows the Tibetan Mastiff looks quite all dogs are actually a subspecies of the Wolf.

We can even make a dog called "House of wolves." However the dog and the Wolf and the difference is obvious. Zoologists have found that the various characteristics of the dogs look more like a newborn Wolf. Physiology check also found the same situation, compared to adult Wolf, adult dogs of adrenaline sensitivity lower, which means that when faced with the pressure and irritation, the dog is more relaxing than Wolf response, less aggressive behavior occurs. All these differences is in ten thousand years of time, and other animals at millions of years of evolutionary history, this is just a moment.

Russia's biologists had reproduced the process.

Bell Guliyev (DmitryBelyaev) in 1959 launched a domestication of the Silver Fox. He is from a Silver Fox farms purchased 30-Fox and 100 to breed only Vixen, and from their offspring, according to certain criteria for selection are friendly to people crossing the little Fox continue. To the 10th generation, 18% of the little Fox has met the selection criteria, the first 20 generations that figure reached 35%, in 1999, after more than 50 generation of uninterrupted picking, 80% of the Silver Fox has become the masters around the spoiled little pets.

Dog King-one optional

Our ancestors in the last ten thousand years on dog did the same thing, the poor who are disobedient, and cooperation "Wolf" are being phased out, and the rest, which is able to accurately read the human gestures and eye's "dog".

This is a "dog King-one optional, the survival of the fittest" story. We choose according to their own standards. These animals brought some people's characteristics, what strange?

United States writer Wiseman (AlanWelsman) in his new book the world without us, "said that if one day people disappear, all dogs will inhabit.

However, Hungary biologists dense Cross (AdamMiklosi) feeding a Wolf and a dog. He taught these animals taken from the box, and then meat to the box lid sealing die. At this point, all dogs go to laboratory personnel present children eagerly watched the people seeking help, and wolves still dogged bite box. "Although the Wolf and the dog are voluptuous interested," Mi Cross said, "but, obviously know if a dog to ask for help, the meat will be easier to get. ”

If no one?
