Question Description



Directions: Answer the short-essay questions with a minimum of three (3) key terms and their definitions in one paragraph. Write each definition in a separate sentence in the paragraph. Begin each question with a topic sentence that answers the question. (You can re-phrase the short-essay question as a statement, for example). Define each key term in a separate sentence. The third question is optional and it is worth five points of extra credit.

  1. What are Primates? Answer both “a” and “b” below:
    • a. What are three features about primates that differentiate them from other mammals?
    • b. What are traits present in the Strepsirrhini suborder that are absent in the Haplorrhine suborder? Name an example species of each suborder.

      Key terms: Primate, Strepsirrhini, Haplorrhine, Platyrrhine, Catarrhine,Tarsiirformes, Simiiformes (or “Anthropoidea”), Lemuriiformes, arboreal adaptation, dietary plasticity, parental investment, rhinarium, incisors, canines, premolars, molars, dental formula, loph, biliophodont molar, Y-5 molar, clade, primitive characteristics, derived characteristics, Stereoscoptic (binocular) vision, diurnal, nocturnal, hominin.

  1. What are at least three traits of New World monkeys (Platyrrhine) that are absent in Old World monkeys (Catarrhine)?

    Key terms: Primate, Platyrrhines, Catarrhines, Anthropoidea, rhinarium, incisors, canines, premolars, molars, dental formula, prehensile tail, premolars, loph, bilophodont molar, X-4 molar, Y-5 molar, clade, primitive characteristics, derived characteristics, diurnal, nocturnal, and Stereoscopic (binocular) vision.

  1. What are the characteristics of chimpanzee alpha males and females? How do you (or a chimpanzee) become an alpha male or female? What are the costs of being an alpha male or female? In your opinion, how are chimpanzees similar to humans? (TEDTalk by Frans de Waal (2012) & (2017))

    Key terms: Primates, social learning, male competition, coalitions, dominance hierarchy, sexual dimorphism, altruism, pro-social behavior, consoler in chief, socioecology, sexual selection, polygynous, polyandrous, monogamous, fitness.
