Questions I previously missed

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
