Questions I previously missed
| Question | Answer |
|---|---|
| Physical anthropologists seek to | study humans from a biological and cultural perspective |
| Adaptive radiation occurs when | species radiate to different environments and adapt to the varying environments |
| According to Darwin, natural selection operates at the level of | individuals |
| Evolutionary synthesis is | a combination of the inheritance of acquired characteristics and natural selection |
| Mendel's plant hybridization experiments demonstrated that | traits inherited from each parent blended together in the offspring |
| The exchange of genes among populations through interbreeding is known as | gene flow |
| Chromosome number is reduced during | meiosis |
| Hox genes | appear to function in similar ways across diverse groups of organisms |
| Dark skin is likely a response to ultraviolet radiation, because UV radiation can cause | skin cancer |
| A skull with a foramen magnum positioned at the back belongs to | an individual that is fully quadrupedal, such as a dog |
| The Y-5 molar morphology is present in | chimpanzees |
| Relative to body size, primate brain size | is larger among great apes than among other primates |
| Primates have long growth and development periods because | they have higher intelligence and larger brains relative to other animals |
| While at the zoo you see an exhibit with a small group of primates and notice they have wet, snout-like noses., indicating | a species of strepsirhini that retain a rhinarium found only in prosimian primates |
| Speech, advanced cognition, and complex material culture | do not define a hominin |
| The first recognizable ancestors of the lineage leading to humans include | Sahelanthropus tchandensis |
| Beginning more than 3 mya, at least two lineages of hominin evolution emerged, one that led to the genus Homo and one that | included the now extinct descendants of Au afarensis |
| The Oldowan Complex includes tools like | choppers, cobbles, flakes and bone tools |
| East Africa robust australopithecines are also called | Papanthropus |
| Australopithecus robustus was likely the longest-surviving species of australopithecine in SA, it had | large molars, a big face and a sagittal crest |
| The ravine in northern Tanzania where many early hominin fossils have been recovered (the cradle of humankind) is | Olduvai Gorge |
| Thick dental enamel in________ helps with crushing food | australopithecines |
| Bipedalism's advantages over quadrupedalism include | an increased ability to see greater distances, and run faster |
| An increased ability to see greater distances is one of the adaptions to | bipedalism |
| Homo habilis experienced a major shift to new environments that was characterized by | tool use for obtaining and processing food |
| What species became increasingly specialized to foods requiring heavy chewing | Australopithecus |
| Some Homo erectus specimens had very large and robust bones while others | were gracile |
| If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, Then A is considered older than B. This is based on | The principle of geolayering |
| During crucial periods of human evolution, the Pleistocene was characterized by | massive glaciation then warm interglacials |
| Which of the following is NOT an ideal environment for fossilization | acidic soil (as in a jungle) |
| Monkeys underwent massive _________ in the Pliocene and Pleistocene | adaptive radiation |
| A species that is adapted to a wide range of environments, climates and diets is | biologically diverse |
