Talking dogs and singing all the voices of birds, the neighbor’s cat crying under the window is not my voice: ‘Murka exit’ All this is not a dream and not a script of the next blockbuster, and possible our future. Genetics of from University of California at Los Angeles and Emory undertook otvetstvennot answer the question: Why people can talk, but our smaller brethren, including monkeys, which are most similar to human, no? Searching for researchers compared the brain response, the speech apparatus and the genomes of people and apes. And they found the answer why so proihodit. The whole point, as it turned out, is human dna. Experts succeeded in isolating the gene responsible for our speech. The name of this Gene – FOXP2. As it became known to the people affected “speech” gene, no matter what efforts are not attached hardly ever learn to speak or pronounce certain sounds.
Exactly the same gene was found in our “little brothers, but only Several vidoizmenneny. Not enough in it only two of some amino acids. What was the reason for the inability of animals to speak. This little defect blocks in the animals ability to make precise movements muscles of the mouth and throat. 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 do not have anything of the kind. Scientists have determined that the ‘voice’ gene in humans began to work in about 200,000 years ago. Which gave a person stand out from all the inhabitants of the earth and take a dominant place in the sun. Experts had learned and implemented the human version of the gene in the mouse dna. After this ekspirementa rodents changed vocalization and squeak became more meaningful. Biologists led by Genevieve and Daniel Geshvinda the University of California at Los Angeles went on the job. They introduced a single mouse brain cells without the gene FOXP2, and the other along with the gene FOXP2. Because of this they managed to vydilt 116 genes controlled ‘colloquial’ genome. Using the results of an experiment in the future date, you can create drugs that will help people get rid of the ‘speech problems’ and even learn to speak “our” little brothers “.
