Flies also know fear like humans

New research by American scientists shows that flies can feel fear like humans and many other emotions.

Flies also know fear

Expert William Gibson and his team of California-Caltech Institute of Technology used darkness to study how flies react to things that are frightening. They put flies in a closed space, where they were screened multiple times with an aerial balloon. The results showed that the flies were startled and if they were flying, they increased their speed. Sometimes, they remain motionless in the same way as rodents react.

The darkness also left the hungry flies out of the area with food and it took some time for them to return to that place. The darker the shadow is, the longer it takes to "calm " the flies and return to the plate for longer.

According to ABC Science, the researchers identified this as the fly running away from the darkness not only to temporarily escape. It is a long physiological state as when people face fear. Gibson and his colleagues say that all of these characteristics are true in the study of flies, so they may actually be as frightened as humans.

This study helps scientists fundamentally understand the factors that create fear and other emotions in animals, especially humans.
