this is an interesting result of a recent study. Here, the researchers trained eight sheep to recognize photos of celebrities and found that these animals actually have a pretty good face recognition ability.

in the study, they used photos of former US President Barack Obama, news anchor Fiona Bruce, actors Emma Watson and Jack Gyllenhaal to familiarize sheep with the faces of these celebrities. First of all, the researchers will first show "familiar faces" and pictures of black screens or objects, and as long as the sheep choose "familiar faces", they will be rewarded accordingly.

then, the researchers added new strange faces to it for the sheep to identify. As a result, the sheep correctly chose the "familiar faces" they had seen before 79% of the time. Even if the portrait in the photo changes its angle, the sheep will not be completely hooked: this time, their accuracy is 66%, which is much higher than random selection.

researchers have confirmed for the first time that sheep can translate a two-dimensional image into a three-dimensional image, which helps them identify the same face from different angles. Perhaps this human-like facial perception is more common in the animal world than we think.

the image of sheep staring at Obama may only seem ridiculous, but the researchers say they do have a serious purpose. They hope to use the sheep to study a range of diseases such as Huntington's disease, in which the inability to recognize faces is an important symptom.
