Dolphins show signs of language-like communication Martin Strmiska/Alamy
Dozens of dolphins have been recorded making specific whistle sounds that seem to refer to a shared meaning, expressing either questioning or alarm. Some researchers are claiming this shared usage is the best evidence yet that these intelligent marine mammals have a language-like communication system.
We know that dolphins make many 鈥渋nformation-carrying鈥 whistling noises, and may communicate extra detail by changing the volume of their whistles, but until now researchers have avoided claiming the animals 鈥 indeed, any other non-human animals 鈥 have a language.
