  1. Communication • Anything that alters the behavior of another

  2. Message (signal) Sender Receiver Interference Feedback Communication model

  3. Which benefits from the communiqué (message) the sender or the receiver? • Example: A skunk raises its tail at a person. What does the person do? Did the receiver benefit from the communiqué? Did the sender benefit from the communiqué?

  4. Function of Communication • Leads to a higher level of predictability • The receiver can predict what will or will not occur • Allows organisms to lie • Ultimately allows organisms to alter their position in the world so they are more successful

  5. Success in Biology • Is measured in the number of offspring.

  6. Evolution of Communication All signals evolve in at least two steps • A signal comes from some adaptive behavior. • The signal becomes ritualized.

  7. Evolutionary Sources for Signals All signals come from 1 of 3 sources: • Autonomic response – a neuronal response, something that cannot be controlled. example: Blushing

  8. 2. Intention movement – a precursor to an action (something that is done before an action) example: forming a fist What is it a precursor to?

  9. 3. Displacement behavior – a misplaced behavior, something that doesn’t fit or belong in the situation. Releases pent-up energy. example: Biting fingernails when nervous
