Biological Anthropology

Order Description
Each this questions should be on one page :
2. Why are chimpanzees frequently held up as a model for understanding human evolution? What morphological and behavioral similarities might they have with early hominins? Is it reasonable to explain these similarities as common adaptations in both species, i.e. Pan and Homo? Why or why not?
3. Some people think that researchers will eventually find the “missing link,” i.e., one organism or species that will clearly tie humans to the other apes and show how they evolved into a new species. Why is it unlikely, from an evolutionary standpoint, that a fossil or set of fossils that perfectly fit the “missing link” scenario will be found?
4. From an evolutionary standpoint, is it logical to expect to find one selective pressure primarily responsible for the appearance of bipedality? Why or why not? What type of selection pressures could affect an organism’s locomotary pattern? Could other evolutionary forces (mutation, gene flow, genetic drift) have influenced the evolution of bipedality? How?
5. Why did Homo erectus successfully expand in and out of Africa? What sort of evidence exists to answer this question?
6. Why are anthropologists so excited about finding evidence of burials or personal adornment in the fossil record? Why is there a time lag between the appearance of modern human morphology and the appearance of the complex symbolic behavior we associate with modern humans? Is there an evolutionary explanation for this?
7. What role do popular misunderstandings about biology and genetics play in modern, everyday conceptualizations of human differences and “race”? First identify two misunderstandings and then explain how they could be dispelled using evidence from modern paleoanthropology.
8. Consider the following statement, “The discipline of anthropology focuses on a bio- cultural approach to explain human diversity, past and present.” How would you explain this statement to someone unfamiliar with the discipline of anthropology? What examples would you use?
