What is heritability? What scientific approaches can be used to determine heritability of a trait? Heritability is when anything is capable of being passed from generation to generation. A trait is heritable because the formation of the brain and specific circuits, even the potential to learn, all require information before learning: genetic information. Any variation in that genetic information is heritable. What examples/pieces of evidence do you know of that show that behaviors can be heritable? Artificial selection, purebred strains, and twin studies. Explain what is meant by “the scientific method.” What is it better than other methods at uncovering the explanations for a particular observation? Includes hypothesis, predictions, data, and tests. Put forward a hypothesis with a prediction difference from that of alternative hypothesis. Collect data. Check results against eh prediction: refute either hypothesis of alternatives. It is very successful and excludes bias. In what ways can the question “Why does animal X show behavior Y?” be answered? Give an example. Which types of questions are called ‘proximate questions’ and which are called ‘ultimate questions’? Proximate (how): physically don’t mate with each other because of body odors. Ultimate (why): incest would increase. Genetic disease would evolve. What are the similarities and differences between selfish, altruistic, mutualistic, and spiteful behavior? They all benefit from the person doing those behaviors, despite whether they are helping other or not. Why is altruism often said to be an ‘evolutionary

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
