1. Much of our behavior is typical of the species yet individually different, even unique. Choose a specific form of one behavior, such as blinking, eating, or speaking, that probably evolved biologically but varies in different people. Suggest an explanation for its constancy in the species and its variability among individuals. It doesn’t have to be an example I mentioned. Choose whatever interests you.
NOTE: You’ll have an easier time with tiny behaviors: a startle reflex, urination, or breathing. Feel free to take on larger traits like problem-solving and mate selection if you wish.
2. When we say that behavior is inherited, we mean that the behavior is influenced by our genes. How do our genes and the environment interact to guide behavior?
