Scientist Gabriel Georgevich claims that sea creatures that were thought to be silent in the past can communicate through vocals. According to Cohen, 53 species in the ocean are capable of sending messages that human beings have never tried to hear.
Using a microphone, Cohen recorded the vocalizations of several species, including turtles. He found out that these aquatic creatures make vocalizations to communicate during breeding and hatching.
The results of the research also showed that all vertebrates that breathe through the nose and use sound to communicate are descended from a common ancestor 400 million years ago. Moreover, the findings of this research claim that all that we know about evolution needs to be rewritten.
Cohen, a Ph.D. student at the University of Zurich, Switzerland, began his research with the idea that marine animals might be able to communicate through sound. The researchers used audio and video equipment to record the sounds of 53 aquatic animals in artificial environments around the world, including Chester Zoo in England. These aquatic animals included 50 turtles, a sea lizard, a lungfish, and a caecilian. Video recordings of the noises helped the researchers compare the sounds with associated behavior to distinguish them from accidental sounds that weren’t made to send a message.
Cohen believes that the sea animals that were thought to be silent in the past, are not silent but their sounds are rather difficult to detect. We know that birds chirp. No one has to tell anyone that, we can all hear it, but some animals are not very vocal, they vocalize or communicate every couple of days or at a frequency that is inaudible to the human ear. Cohen further criticized that humans are more biased toward land-dwelling creatures and therefore ignore underwater species.
