A scientist has identified 53 species of sea creatures that ‘talk’ to each other but were previously thought to be silent or mute. Researcher Gabriel Georgovich Cohen believes that these sea creatures have always been sending messages to each other, but humans have never tried to listen. officerswiki
Gabriel used a microphone to record the sounds of animals that wanted to mate or hatch, including sea turtles. The information gained from this research is claimed to redefine our understanding of evolution.
The new information suggests that vertebrates that breathe through their noses and communicate with each other through sound share a common ancestor 400 million years ago. This is a huge claim for evolutionary biology, which argues that all living things started from a common ancestor.
Gabriel is a Ph.D. student at the University of Zurich in Switzerland. He began his research overwhelmed by the idea that marine animals might use sounds to communicate with each other. They captured and recorded 53 species of marine animals around the world with the help of audio and video recording equipment. Among the animals were 50 turtles, a tuatara (a chameleon-like animal with spine-like protrusions on its back), a lingfish and a caecilian.
These animals were thought to be mute, but Gabriel believes that their sounds have not reached us because they were difficult to detect. Talking to BBC News, he said that ‘when the birds chirp, we know. No one needs to be told what it is, but some of them are very quiet or make a sound once in two days.’
With the help of video, Gabriel explored the relationship between sound and the resulting behavior. This helped to isolate unintentional or accidental sounds. He says, ‘Sea turtles make sounds before hatching. In this way, several children go out together to avoid being preyed upon by other animals. They say that turtles make sounds when they want to meet for breeding. evolution
Gabriel also recorded a video of a tuatara (a chameleon-like animal with spine-like protrusions on its back) making sounds to deter anyone from entering its territory. Using phylogenetic techniques for analysis, Gabriel traced the interrelationships of vocalizing animals.
This method compares the behavior of different species and divides them into different groups. For example, as humans and non-humans produce sounds, it means that their common ancestors also used to produce sounds. Gabriel believes that the descendants of animals that communicate by sound are the same that lived in the Devonian period, 400 million years ago. This was the time when most living things lived below the surface of the water. It was previously thought that the use of sound for communication began 200 million years ago.
