Genetics is the study of genes and the variation of characteristics that are influenced by genes—including physical and psychological characteristics. A Harvard professor teaching genetics and behavior had invited Hamer to submit a pamphlet describing his research as an example of "conceptual advances" in "modern behavior genetic studies." People normally have 46 chromosomes in each cell. A … The amazing story of adaptation and survival in our species, Homo sapiens, is written in the language of our genes, in every cell of our bodies—as well as in the fossil and behavioral evidence.

Those listed here, including Rutter 2006 and Kim 2009, are intended to be fairly general and cover a broad array of behaviors.In addition, Segal, et al. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?.
