A new study shows that fish can detect the fear of other fish.
You will be surprised to know that one fish fishes Can find out the fear of. Not only this, feeling that fear, she herself also gets very nervous. One Study This thing has come to the fore. According to this study, our ability to take care of each other may be centuries old. In a study published Thursday in the journal Science researchers According to it, its roots can be traced back to the period millions of years ago when Human And the animals used to roam in the forests together.
Hans Hoffman, a neuroscientist at the University of Texas at Austin who was not part of the research, believes that some of the mechanisms by which we experience fear and love are apparently very ancient. Scientists generally refuse to believe that animals have feelings like humans. But it is also commonly accepted that many animals including fish have moods.
fish behave like humans
A new study has found that fish can detect the fear of other fish and then get scared themselves. This ability inside the fish is controlled by oxytocin. This is the same chemical that develops the ability of empathy within humans. The researchers demonstrated in zebrafish that the gene associated with the production and absorption of oxytocin had been removed from the brain. Please tell that zebrafish is a tropical fish which is often used for research. These fish were anti-social and failed to detect their behavior when other fish with them were worried.

Fish recognize fear with oxytocin
On the other hand, the fishes which were given oxytocin injection, those fishes were understanding the feeling of other fishes and this ability was also visible in their behavior. What scientists call emotional contagion. When the other fish with him got scared, he reacted. This information was given by Neuroscientist Ibukun of the University of Calgary, who is also the co-author of this study. It was also found in this study that they will pay more attention to those fish which are under stress. She does this to console them.
Hoffman explained that this brain processing may date back 450 million years, when you, me and these little fish had a common ancestor. Oxytocin, sometimes thought of as the love hormone, is actually more like a thermostat that determines what is socially salient in a particular situation.
