Dolphins can be the only creatures on Earth except people who give each other names and respond to them 
Open Source Researchers at St Andrews University of Scotland made another breakthrough in language learning dolphins, having first discovered proper names in it. Earlier it was believed that only a person can give names to relatives. Researchers analyzed whistles – the most advanced remedy. dolphin vocalizations: these animals can issue at least 32 different kinds of ultrasonic whistles. They recorded acoustic the signals exchanged by dolphins at sea, and found that a significant part of them falls on the so-called “names”. In one from experiments, scientists placed sound reproducing devices in pool and found out that dolphins do not respond to other people’s “names”, but but they react vividly when the recording in the speakers called them themselves. So Thus, we managed to isolate whistles from the dolphin language, which perform the same role as personal names in human speech. IN press release on the university website Stephanie King (Stephanie King) one of the researchers who conducted the experiments noted: “It has long been it has been found that animals can use sounds to alert predators or food, however, these cries appeared and took shape during evolution. Using new and learned sounds to signify things is rare in the animal kingdom. “Whistles spread in water up to a distance of 20 kilometers and allow dolphins maintain contact within the flock. “Usually people are shown in television movies that dolphins swim in clear water and few realizes that they spend most of their life in fact in the dark, where they cannot smell or see a partner, “- how noted in an interview with The Daily Mail, King’s colleague, Vincent Janick (Vincent Janik), dolphins would never be able to keep strong communication in packs, if not for whistling communication. At the same time, Yanik added that a similar ability to give names and respond to them not even the closest relatives of man, higher primates. Most scientists believe that dolphins have real the language in which they communicate with each other. It was possible to single out a series of acoustic signals whose value can be reliably to establish, however, a complete decoding of the dolphin language remains business of the future. July 23 is World Whale Day and dolphins. Initially, the festival was established to protect whales, however over time it turned into a day of protection for all marine mammals. The size of the dolphin population in the oceans has not yet ecologists fear, however, due to oil spills and fishing nets kill many of these mammals. Threatens them and overfishing, and in some countries, including Japan, Solomon and Faroe Islands still practice killing dolphins for eating. According to foreign materials MEDIA. Konstantin Kerubov
