Final answer:
Research after the original universality studies on facial expressions found that contempt is another universally recognized facial expression, adding to the previously identified emotions like disgust and anger.
Step-by-step explanation:
After the original universality studies on facial expressions, research demonstrated evidence that contempt was also a facial expression universally recognized. This conclusion extends the work of Paul Ekman, who identified seven universal emotions with distinct facial expressions: happiness, surprise, sadness, fright, disgust, contempt, and anger. These findings suggest that there are consistent facial expressions across different cultures that convey specific emotions, pointing to the genetic and evolutionary roots of our emotional expressions.
