Natural selection generally favors behaviors thatEnhance survival and reproduction
Sexual dimorphismConcerns differences in body size and canine size
Sexual selection is best defined asNatural selection by traits attractiveness to opposite sex
Altruistic behaviorIs behavior that aids others; disadvantage to individual
Vocalization in chimp groupsIs unique to specific groups or regions
Gibbons demonstrate the lack of sexual dimorphismDue to decreased competition for mates in monogamous society
