dog's eyes evolve to appeal to humans

    If a dog has eyes that seem to be telling you something or demanding your attention, it could be evolution's way of manipulating your feelings. Researchers have found that dogs have evolved muscles around their eyes, which allow them to make expressions that particularly seems  to be human expressions. Previous studies have shown how such canine expressions can appeal to humans, but this research from the UK and US shows there has been an anatomic change around dogs' eyes to make it possible.
