Sheep are able to recognize people (in photographs)

He recognition of human faces from photographic portraits, and even the identification of the image of your trainer without prior training, is a skill that can be trained in sheep, according to a recent study carried out by the University of Cambridge and published in Royal Society: Open Science.

Human faces

As with dogs and monkeys, sheep can recognize other sheep and known human beings, according to researchers from the Cambridge Department of Physiology, Development and Neuroscience trained eight sheep to recognize the faces of four celebrities from photographic portraits shown on computer screens.

The sheep correctly chose the face of the celebrity eight times out of ten. This happened with the front faces, if the faces were shown at an angle, the yield was only reduced by 15%.

All this, in addition, has a practical value, as he explains Jenny Morton, who led the study:

Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand brain disorders, such as Huntington's disease, that develop over a long time and affect cognitive abilities. Our study gives us another way to monitor how these skills change, particularly in sheep that have the genetic mutation that causes Huntington's disease.
