- While observing primates at the zoo, you notice that the particular monkey you are watching uses its hands, feet, and tail to grasp branches while moving throughout the trees in its enclosure. This is most likely a(n) A. New World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primates hands and feet B. Old World monkey, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feet C. New World monkey, because these are the only monkeys that live in trees D. Lesser ape, because many of these species have a tail with grasping abilities similar to those observed in nonhuman primate hands and feetarrow_forward. In white-crowned sparrows, social experience exhibits a very stronginfluence over the development of singing patterns. What observation led to this conclusion?a. Birds learned to sing only when they were trained by other birds.b. The window in which birds learn from other birds is wider thanthat in which birds learn from tape recordings.c. Birds could learn different dialects only from other birds.d. Birds that learned to sing from a tape recorder could change theirsong when they listened to another bird.arrow_forwardWhat is the status of the hypothesis that language evolved as a by-product of overall intelligence? a. It is supported by findings that total brain mass correlates highly with language ability. b. It is supported by findings that teaching language to other primates causes an enormous amount of brain expansion. c. It is contradicted by findings that brain damage has no effect on language. d. It is contradicted by findings that some people have normal intelligence without language, and others have normal language despite mental retardation in many other regards.arrow_forward
