English scientists have discovered that bees can recognize human faces and remember them, sometimes even after a few days.
|But will this bee have recognized the face of former US president Bill Clinton?|
Adrian Dyer and his team at the University of Cambridge (England) have discovered that bees can recognize human faces and remember them, sometimes even after a few days. The group of scholars placed bees near four photos of human faces. The experiment consisted in rewarding with a sugary substance the bees that approached one of the four images. Once the reward was removed, the bees continued to approach the photo in question: five of the seven bees involved in the experiment "recognized" the exact face in eighty percent of the attempts.
It would therefore seem that these insects have a minimal capacity to recognize faces and to memorize them even in the long term. Not bad for an animal without a cerebral cortex (the area of the brain responsible for human recognition) and with 0.01 percent of human neurons.
Narcotics. In the past, some experiments had shown that bees possess complex faculties: they communicate very precisely through "complex dances" and very complex vaults and would seem able to count. They would also have a certain self-awareness of themselves: in a 2002 experiment, some bees had been marked with color and placed in front of a mirror. As soon as they saw themselves in the mirror, they tried to get rid of the extraneous color off them.
