This chapter outlined four reasons why behavior is not determined by genes in the sense of "if you have this allele, you will act this way":
1. The transcription of genes is regulated, so expression of an allele is a function of action by hormones, neurotransmitters, and other signals.
2. Gene products function only in concert with many other gene products, so their effect varies with the amount and identity of these other molecules.
3. Individuals frequently have a large repertoire of different types of behavior; which behavior is used depends on the social environment and other types of conditions.
4. Genetic differences among individuals invariably produce statistical differences in behavior, not either-or responses.
Using the data reviewed in this chapter, or other examples you are aware of, provide a case that illustrates each of these four points.

To study how displays or other types of behavior have changed through time, why must researchers know the phylogeny, or evolutionary history, of the species involved?
