Dr. Alan McElligott led a study at Queen Mary University of London that determined goats react to human facial expressions. Dr. McElligott found that goats prefer smiling or happy faces to ones that were angry. The study also showed that they also use the left hemisphere of their brains to process emotions.
Previous studies have shown that dogs, cats and horses and many other animals also recognize facial expressions in humans and react to them accordingly. With each study we learn more about the animal kingdom and how alike in many ways all animals are.
