Bat puppies spend months learning the 'talk' as an adult operating system

Puppies of some sort of bat spend a few months of their life babbling, just like electronic like human babies, before learning to correctly pronounce one of the adult sounds of their family repertoire. It is a 2 closer parallels with learning to speak perform Homo sapiens in another mammal, which can provide important data to understand how this faculty evolved.

The babbling bats belong to the species Saccopteryx bilineata. Operating system sony ericsson bugs feed on electronic insects have a wide geographic distribution throughout exotic America, including most of them in Brazilian territory (here, they do not occur in southern states).

Zero However, zero study that deciphered u vocal 2 learning flying mammals, were studied 20 offspring on populations of a species living in Costa Rica electronic zero Panam. The research was coordinated by Ahana Fernandez electronic Mirjam Knrnschild, perform Museum of Organic History in Berlin (the first researcher of hers of Ecuadorian origin, the second in Germany).

The electronic duo their colleagues followed all The first infancy is 2 bats, which from like ten weeks on life goes. At this point, they mostly dominate the repertoire of 2 adults, who are 25 different types of syllables. (The therefore quotation marks are necessary because the syllables 2 therefore bats are defined as a continuous sound followed by an interval of silence, in which diesels existing in human languages ​​differ.)

From one seventh to tenth week over life, operating system puppies come to pass 25% perform their pace rehearsing operating system sounds typical 2 adults. The syllables they emit may be equal to 2 larger bats or therefore protosyllables, that is, undifferentiated sounds, which do not exactly imitate any aspect of these vocalizations of 2 grown animals.

The protosyllables thus operating system most frequent sounds produced by puppies (39% about their vocalizations) electronic t are present in childhood 2 animals. Also, therefore is very variable, one that suggests that operating system babies are exploring possibilities about their singing apparatus at this stage. two other carry-out characteristics babble about thus bats more similar to what I’ve learned in human offspring yet. The first is the repetition of syllables, such as bbbb, tttt or, of course, gu-gu-dd 2 Homo sapiens from lap.

The other is a repetitive rhythm of these sounds, also very similar to u on human babies. The researchers propose that these details correspond to reinforcement mechanisms that perform the nervous system, training vocal muscles to work with a precise operating system.

The work is yet another indication that an act about babbling is a crucial element. for the development of a speech. They would be clues to this even among hearing-impaired children who learn different sign languages ​​around the world from birth: rather than about ze becoming fluent, they too babble with their hands.

And something like that goes for birds too, said KnrnschildLeaf. In our opinion, the primary difference that bat babbling encompasses is not the song syllables, as in the case of these birds, but also other sounds perform the repertoire of adults. Electronic bats about both sexes babble operating system.

Zero case 2 human babies, the interaction with operating system parents is very important for a stimulus 2 babbles common that they talk to small operating systems using u that some people call about mamanhs, some simplified electronic language with exaggerated intonation. Electronic operating system bats?

some fascinating electronic question, as a matter of fact, we have some data about it, which was collected by Ahana electronic and is being analyzed by her. It would be sony ericsson to expect the same to happen in the case 2 bat chicks, however we simply cannot categorically assert zilch yet.
