Questions I got correct
| Question | Answer |
|---|---|
| Multiple biological traits | do not lead to clear-cut racial classifications |
| Children living at high altitudes develop a larger chest cavity by adulthood that children living at lower altitudes. This is an example of | Developmental adaptions that occur at the level of the individual during critical life stages |
| Although Allen's and Bergmann's rules most often explain body shape and morphology, we occasionally se variations from the correct patterns. This indicates that | The association between body shape and morphology does respond to environmental stressors |
| Allen's rule indicates that humans will have | Longer limbs in hot environments and shorter limbs in cold environments |
| The obesity pandemic is due to | the increased ability to produce and consume inexpensive, high fat foods |
| When epiphyses fuse to the diaphyses | full adult height is attained |
| Genetic Adaption | occurs at the population level via natural selection |
| Acclimatization | occurs at the individual level throughout an individual's lifetime |
| Melanin | is advantageous because it provides protection from solar radiation |
| Relative to people with a history of living in temperate climates, the Inuit and other cold-adapted populations | have short limbs and large bodies |
| Sexual dimorphism | refers to the difference in physical attributes of males and females |
| Natural Selection favored alleles for light skin in | Europe |
| The long limb measurements of Turkana pastoralists indicate that | The population is on the continuum of variation observed in Allen's rule |
| Which is a major contributor to the success of our species? | Human adaptability |
| A cline is | continuous variation that follows a continuum |
| Primate females | give birth to fewer offspring than do many other mammals |
| The suborder prosimians includes | diurnal and nocturnal lemurs |
| Anthropoids include | monkeys, apes, and humans |
| The genetic classification for apes and humans | includes three subfamilies within hominids: pongines, gorilines, and hominines |
| Relative to other primates, prosimian adaptions include | an enlarged olfactory bulb and enlarged scent glands |
| Prehensile traits | are present only in some platyrrhines |
| Arboreal adaption is | adaption to life in the trees |
| In class your professor shows you an MRI scan of a primate brain. The professor points out the relatively large size of the olfactory bulb beneath the frontal lobe. This suggests that | this may be a species of Old World monkey or ape, as the space in the teeth of the mandible suggests the presence of a canine-premolar honing complex |
| The rhinarium is present in | ring-tail lemurs |
| Living lemurs are found only in | Madagascar |
| Dietary plasticity in primates refers to | eating a wide variety of foods |
| Among all primates, humans have | the largest brains relative to body size |
| The cladistics approach to primate classification is | based on the use of anatomical and genetic evidence to establish ancestral lines |
| Phylogeny refers to | evolutionary relationships that are based on shared characteristics including physical traits, genetics, and behavior |
| The variation in living primates provides models for understanding | morphology, behavior, and adaption in the evolutionary past |
| Primates are characterized by | arboreal adaption, dietary plasticity, ad parental investment |
| Brachiation refers to | using the forelimbs to move from tree limb to tree limb |
| Catarrhines' nostrils are | close together and face downward |
| Modern primate are characterized by arboreal adaptions, including | opposable thumbs |
| Primates' enhanced sense of vision stems from | Both a and c (the fact that their eyes are rotated forward, their color vision) |
| Monogamous refers to | a social group that includes an adult male, an adult female and their offspring |
| Sexual selection | is the frequency of a atrait's attractiveness to members of the opposite sex |
| Grooming involves | bonding between two members of a social group, calming or appeasing the primate being groomed if he or she has a higher dominance |
| Kin selection refers to | altruistic behavior that increases the donor's inclusive fitness and that of the donor's relatives |
| Quality in feeding strategy refers to | a food's providing energy and protein that are readily digestible |
| The study of primate vocal communication | can give us insights into the selective pressures that may have shaped the evolution of language |
| Why are primates social in the long term | to reduce stress, promote longevity, and enhance reproductive success |
| Female Reproductive strategies emphasize | caring for young and ensuring access to food |
| Male reproductive strategies emphasize | competition between males for access to reproductive age females |
| A male and female gibbon that are similar in size are likely showing | the lack of sexual dimorphism due to decreased competition for mates in a monogamous social structure |
| Polyandrous residence patterns represent | a social grouping in which males cooperate in parenting activities |
| Male primates most often compete for mates while female primates compete for other resources, demonstrating that | reproduction places different energy demands on males and females, resulting in varying reproductive strategies |
| Natural Selection favors behaviors that enhance | survival and reproduction |
| Primatologists | explore the relationships between specific social behaviors and reproductive fitness |
| Sexual dimorphism | concerns differences in body size and canine size |
| Grooming invloves | Bonding between two members of a social group, calming or appeasing the primate being groomed if he or she has a higher dominance |
