A study revealed on Wednesday, Researchers have found that Goats can distinguish smiling human faces from angry ones on photos, and actively seek out pictures of happier individuals they had never met before.
Shown two pictures of the same person — one with a happy expression and the other angry — 20 domesticated goats in an experiment were more likely to approach the smiling image and touch it with their snout, said researchers from Europe and Brazil.
“Goats looked and interacted on average 1.4 seconds with the happy faces and 0.9 seconds with the angry faces,” study co-author Christian Nawroth of the Queen Mary University of London said.
“That means that goats spend approximately 50% more time to look and interact with happy images compared to angry ones.”
The study, published in Royal Society Open Science, claims to provide the first evidence of goats reading human emotional expression. The findings suggested “livestock species have very sophisticated minds to interpret their environment,” said Mr. Nawroth.
“The study has important implications for how we interact with livestock and other species,” said Mr. Nawroth’s colleague Alan McElligott
