Talking dogs and singing all the voices of birds, a neighbor's cat crying under the window in an unnatural voice: 'Come out Murka' … All this is not a dream scenario and not the next blockbuster, and possible future of our blizheshee. Genetics of from University of California at Los Angeles and Emory made a otvetstvennot answer the question: Why people can talk, but our brothers are smaller, including monkeys, which are most similar to human, no? Searching for researchers compared the brain response, the speech apparatus and the genomes of humans and apes. And they found an answer why proihodit. It's all about, as it turned out, is human DNA. Experts have managed to isolate the gene responsible for our speech. The name of this Gene – FOXP2. As it became known to the affected people 'speech' genome, no matter what efforts are not attached are unlikely to ever learn to speak or pronounce certain sounds.

Exactly the same gene was found in our younger brothers, but only several vidoizmenneny. It is not enough to just two of some amino acids. What was the reason for inability to talk to animals. This small defect blocks in animals can make precise movements mouth and throat muscles. And as a consequence makes it impossible for the emergence of spoken language in animals. – In addition, we found out that the brains of people have already been prepared at birth to speech – says the discovery of Dr.

Daniel Geshvind. – A chimp babies does not have such. Scientists have determined that the 'voice' gene in humans began to work about 200 000 years ago. Which gave the person stand out from all the inhabitants of the earth and take a dominant place in the sun. The experts had experience and have implemented a human version of the gene in mouse DNA. After that ekspirementa rodent vocalization changed and squeak became more meaningful. Biologists led by Genevieve Konopka and Daniel Geshvinda University of California at Los Angeles went on the job. They introduced a single mouse brain cells without the gene FOXP2, and the other with a gene FOXP2. Because of this they were able to vydilt 116 genes controlled 'colloquial' genome. Using the results of an experiment in the future for, you can create drugs that will help people get rid of the 'speech problems' and even learn to talk to 'our younger brothers'.
