Scientists have discovered that dolphins are capable of speaking like humans – at least something close.
It has always been known that dolphins are high intelligence animals who can communicate in groups, but their ability to communicate individually has never really been understood.
Researchers at the Karadag Nature Reserve, Feodosia, Crimea, have come up with a way to understand how they communicate individually.
According to the researchers, the clicks and whistles made by the animals are fully paid attention to before a response is made.
“Essentially, this exchange resembles a conversation between two people,” wrote lead researcher Dr Vyacheslav Ryabov.
Dr Ryabov explained that each pulse of a dolphin differs from another by time span and frequency.
“In this regard, we can assume that each pulse represents a phoneme or a word of the dolphin’s spoken language,” Dr Ryabov wrote.
“The dolphin’s speech unfortunately lies beyond the time and frequency characteristics of the human hearing, and is thus unavailable to humans.”
The study experimented on two adult Black Sea bottlenose captive dolphins called Yana and Yasha. They had lived in a swimming pool for 20 years. The swimming pool measured 27 metres by 9.5 metres and is four metres in depth. An audio system attached to the pool recorded their “conversations”.
The study noted that the sounds emitted between Yana and Yasha were quite different compared to sounds emitted among a school of dolphins.
Dr Ryabov said:
“The analysis of numerous pulses registered in our experiments showed that the dolphins took turns in producing pulse packs and did not interrupt each other, which gives reason to believe that each of the dolphins listened to the other’s pulses before producing its own.
“This language exhibits all the design features present in the human spoken language, this indicates a high level of intelligence and consciousness in dolphins, and their language can be ostensibly considered a highly developed spoken language, akin to the human language.”
The study was published in the journal Mathematics and Physics.
