That’s from Phys.org. The lede:

Goats can differentiate between human facial expressions and prefer to interact with happy people, according to a new study led by scientists at Queen Mary University of London.

And:

The study, which provides the first evidence of how goats read human emotional expressions, implies that the ability of animals to perceive human facial cues is not limited to those with a long history of domestication as companions, such as dogs and horses.

Intersting. And intuitive. Everyone/thing appreciates a good smile! 🙂
