Animal Personality
Animal personality has been studied for decades, and a recent renaissance in the field has revealed links to health and life outcomes that echo those found in humans. Some of this research is tied to the Five Factor Model—the predominant model of human personality—which informs animal personality research as well, and allows for comparative work that points to evolutionary pathways that delineate phylogenetic continuity. From personality facets and traits to factors, this work has implications for human and nonhuman animal genetics, life history strategies, survival, and well-being, as well as development and social relationships. Working together, scientists from a variety of fields who study personality can hope to puzzle out causality, use personality as a tool for health, and simply define personality, across species, and therefore evolutionary time.
