1. How is non-verbal communication explained?

3. Darwin’s Evolutionary Theory of Non-Verbal Communication
For a species to evolve, organisms must survive and reproduce
Genes that make an organism more likely to survive and reproduce are more likely to be passed on to the next generation
Adaptive organisms are more likely to survive and reproduce

4. Darwin’s Evolutionary Theory of Non-Verbal Communication
Serviceable habit (Initial physiological function that would increase the chance of survival)
Serviceable associated habit (evolved communication function)
Darwin’s Evolutionary Theory of Non-Verbal Communication

5. What was the original physiological function of these behaviors
What was the original physiological function of these behaviors? What communication function do they now serve?

6. Darwin also said some non- verbal behaviour is a result of our nervous system, e.g. adrenaline causes pupils to dilate making us look frightened, or blushing, or tap our feet when agitated

7. Is Non-Verbal Behaviour Learned or Innate?

8. Argument: Non-Verbal Behaviour is Innate

9. Argument: Non-Verbal Behaviour is Learned
