Document Summary

Behavior is study of how and why organisms respond to stimuli in their environment. How behavior occurs (genetic, neural, hormonal mechanisms, etc) Why behavior occurs (evolutionary history and function) Sender (send messages) and receiver (makes a decision and reaction) Sending of message depends on the environment and reaction to message depends on environment. Plants send message to animals to get food, then animal feeds. But not all messages convey truthful information. Batesian mimicry - a harmless species copies phenotype of species that is protected. Signals - traits fashioned maintained by natural selection because they convey information to other organisms. Honest (reliable) - signals contain correct/useful information. Those evolved to function to communication (signals) Flashing used to find mates - males and females have different flash patterns. Any male with a novel flash pattern would experience difficult obtaining a. Deceitful signals - stable if receivers typically benefit from responding to them.
