Like Threaten Like in Mangabeys <i>and People?</i>

Abstract

AbstractAdult golden-bellied mangabeys (Cercocebus galeritus chrysogaster) housed in three structures directed more frequent aggressive facial displays toward human visitors of their same sex than toward humans of other sex. The human male visitors showed the same patterns as did the mangabeys, with men harassing males. Human females were the only ones that did not display this pattern. Infants and small juveniles did not threaten each other across species. All targets of aggression do not produce the same sex differences in mangabey facial threats.
