Biological factors and aggression.
AbstractNotes that the publication of Darwin's theory of evolution in 1859 (Darwin, 1859/1936) had a profound impact in grounding human behavior in evolutionary history. The implication was that much human behavior might be explained in terms of the same mechanisms that cause behavior in other organisms. Among the biological factors that have been posited to cause aggressive behavior are instincts, genes, pain-elicited reflexive fighting, hormones, brain structures, and an inborn aggressive drive. We examine research carried out on these factors to ascertain their impact on human aggression. (PsycINFO Database Record (c) 2009 APA, all rights reserved)
