Answer:
Facial behavior has an innate, unlearned component.
Explanation:
The debate of nature vs. nurture is one of the most important ones in the social sciences. "Nature" states that some traits are innate to humans, and are already within us the moment we are born. On the other hand, "nurture" refers to the idea that it is society that teaches us some of our traits, and we adopt them based on our culture. What this research wants to show is that human facial behaviour has a component that is innate and unlearned.
