Your Answer: Explanation Monogamy is the practice of having a single sexual partner during a period of time. Sexual dimorphism is low because males and females cooperate in territorial defense. Question 35 of 55 Among orangutans, females associate with their infants while males are solitary. Males are solitary, but attempt to maintain a territory that includes several females.

Your Answer: Explanation Male-male competition probably explains the high size sexual dimorphism in orangutans. Question 36 of 55 All primates exhibit pentadactyly (they have five fingers), a generalized dental pattern, and a primitive (unspecialized) body plan. Your Answer: Explanation Another distinguishing feature of primates is fingernails. Opposing thumbs are also a defining primates feature, but are not limited to this order; opossums, for example, also have opposing thumbs. Question 37 of 55 The anatomical and behavioral features that distinguish primates from members of other mammalian orders include a lack of strong specialization in structure; prehensile hands and feet, usually with opposable thumbs and great toes; flattened nails instead of claws on the digits; acute vision with some degree of binocular vision; relatively large brain exhibiting a degree of cortical folding; and prolonged postnatal dependency (longer dependence on the parents after birth). Your Answer: Explanation No primate exhibits all these features, and indeed the diversity of primate forms has produced disagreement as to their proper classification. Question 38 of 55 The smallest primates are weighed in tens of grams, while the Gorilla typically weighs 140 to 180 kilograms (300 to 400 pounds). Your Answer: Explanation Nonhuman primates are found throughout the tropical areas of India, Africa, Asia, and South America. A few species also live in temperate latitudes, but lack of winter food supply limits their adaptability to these climates. Question 39 of 55 Most primates have binocular vision and forward-facing eyes, two characteristics that are necessary for depth perception. Your Answer:

Explanation Although their vision is highly developed, primates have shortened muzzles and a correspondingly reduced sense of smell. Question 40 of 55 Except for two species, all primates have five digits on each hand and foot. All have prehensile (grasping ) hands, and all except man have prehensile feet. Your Answer: Explanation Although the opposable (freely moving) thumb is present in most primates, it is particularly developed in man, making him capable of delicate manipulation. Question 41 of 55 A trend in primate evolution has been toward a more elaborate brain. In higher primates, the neocortex functions to receive, analyze, and synthesize information from the senses.
