An important breakthrough occured In 2008: researchers in Great Britain and the United States created the CymaScope
It is making "CymaGlyphs," as they have been named: those are reproducible patterns that are expected to form the basis of a lexicon of dolphin language, each pattern representing a dolphin ‘picture word.’
The doctor Lilly made a lot of experiences with dolphins. He made this proposal: Human baby is: age brain weight imitating sounds 5/6 months 650 g first articulate word 9 months 770 g more complex vocabulary 12/13 months 990 g naming objects and images 18 months 1030 g combining words 21 months 1060 g doing correct sentences 2 years Finally he says that there is a link betwin the quantity of gray matter and the ability to have a complex and organized language.
In “Thoses Beautiful Intelligences : Big Monkeys and Dolphins.”, Maddalena Bearzi explained dolphins have complex behaviours. For exemple one of them ; Kelly, was able to make savings and investisments.
She (it) collected the object the tourists were losing to use them as a bargaining chip one by one to have more food. Then she manage to capture a gull with the fish and she had to eat then get a good reward for that. And finally she learned this to her children.
Discovered by Randy Wells from the Mote Marine Laboratory, the signature whistle is related to our humans name and first name.
It has 3 parts: the first half correspond to the name of the mother (“family name”), then one quarter for the group of belonging (“nationality”), and the last quarter is specific of the individual (“first name”).
This signature whistle can be sent out between 20 and 30 times per second. It informs the other dolphins about his emotional state.
