an ancestral mammalian pattern retained to some degree in most primate species
in Euocene primates (euprimates) the recognizable and modern derived primate traits are:
forward facing eyes opposable big toes
as an order, primates:
have generalized traits
in laboratory experiments, monkeys raised without mothers
displayed abnormal social behaviors
the primate emphasis on the visual sense is reflected in:
the reduction in the size of structure related to sense of smell presence of color vision in most species a more forward facing position of the eyes relative to most other mammals
the order primates is traditionally divided into two suborders:
prosimii and anthropoidea
What is seen in NW monkeys but not in OW monkeys
if females of a given primate group are philopatric, it means that females:
remain in one's natal group as an adult
different species that share the same habitat are said to be:
primatologists consider chimpanzee "termite fishing" an example of cultural behavior because ...
it is a learned behavior that continues as a within-group tradition it involves tool preparation and use
amicable behaviors that promote group cohesion are called ...
some taxonomists have developed an alternate system of classification in which tarsiers, monkeys, apes and humans are placed together in the suborder:
in the context of social groups, dominance hierarchies
impose a certain amount of order within the group
species that produce relative large numbers of offspring and invest littler parental care are said to be:
he traditional view of nonhuman communication has been that nonhumans, including primates:
communicate information relating tot heir emotional state only
which of the following hominids has the most primitive (ancestral) traits?
traditionally, primate characteristics have been explained as the result of adaptations to what kind of environment?
what is the study of the evolution of behavior, emphasizing the role of ecological factors as agents of natural selection?
a sagittal crest is:
a characteristic of some "robust" australopithecines a raised ridge of bone running along the midline of the cranium for the attachment of muscles
the Y-5 molar:
have 5 cusps with a groove running between them
paleoanthropologists are interested in nonhuman primate tool use because:
possibly resembles tool use in early hominins
what does a defect in Wernicke's area of the brain cause?
issue related to language comprehension
linguistic symbols, like English letters, do not resemble the object or concept they represent and are described as:
amicable behaviors that promote group cohesion are called ____ behaviors
taxonomists have developed an alternate system of classification in which tarsiers are removed from the ____ suborder and placed with monkeys, apes and humans in the suborder _____
when a male langur takes over another male's group, they sometimes kill the young infants. the evolutionary explanation for this behavior is that:
increases the reproductive success of the male causes the infant's mother to cease lactation and resume estrous/reproductive cycling mother becomes sexually receptive/available to the new, dominant male
in nonhuman primates, the most rapid period of brain development occurs:
