Q10. In his bооk 1830 Principles оf Geology, Chаrles Lyell described how geologicаl processes shаping the surface of the earth today (e.g. erosion and sedimentation) are also the processes that shaped the earth in the past. Given enough time, _________processes (not catastrophes) can explain most of the history of this earth as recorded in the geological record. During his voyage on the Beagle, Darwin read this book and began to conceptualize that gradual change happening over a long time scale might also explain the origin of new species. Q11. A hummingbird has a long, curved beak which is ideally suited for extracting nectar from flowers. While this kind of good fit between an organism and its environment was traditionally interpreted to be evidence of a supernatural “designer,” Darwin offered a naturalistic explanation for such “design.” Acting on the enormous variation present in natural populations, natural selection produces directional change in a species, making a species seem as if it were “designed” for its current environment. Darwin’s idea brought biological organisms under the umbrella of ___________explanation (extending the ___________revolution which began centuries earlier with physical phenomena like the rotation of the earth around the sun). [Note: The same word is used for both blanks] Q12. Darwinism is the name given to the idea that evolution is the result of the action of natural selection producing change in successive populations. ________is a more evolved version of evolutionary explanation which includes an understanding of the role of genetics in producing and redistributing the enormous amounts of variation found in natural populations. Q13. ________developed a highly successful system for classifying living organisms that placed every species within a nested series of hierarchically-arranged categories. Although he did not understand the reason why this pattern existed in nature, biologists would later explain this as evidence that all contemporary organisms are descended from a common ancestor. Q14. In his book The Descent of Man and Selection in Relation to Sex (1871) ________ introduced the concept of sexual selection to explain how a trait which makes an individual vulnerable to predation (such as the peacock’s tail) might exist in a species because females find it attractive. Q15. Gregor Mendel proposed a model of inheritance based on his observations of seven traits of simple inheritance in the garden pea plant (each of these seven traits was controlled by one gene locus). Population geneticists like Dobzhansky showed that Mendel’s model of discrete inheritance also applied to traits of complex inheritance such as skin color in which multiple ________ control the expression of the trait. Q16. In 1902, Walter Sutton proposed that Mendel’s hereditary factors (“genes”) ride on the _________he saw in the nucleus of each cell when he examined dividing cells with a light microscope. He pointed out that Mendel’s Laws of Segregation and Independent Assortment were consistent with the movement of _________ during meiosis. [Note: The same word is used in both blanks] Q17. Geneticists study inheritance at the level of population, organism, cell and ________. When there is good “fit” between knowledge generated at each level of analysis, scientists have increased confidence that they are describing a single reality and have a correct understanding of the relationship of genes, proteins and traits. Q18. The Human _________Project has completed its goal of sequencing all three billion base pairs found in the DNA of 46 human chromosomes. Scientists are still sorting out which segments code for proteins (i.e. which are genes) and how these proteins function in humans. The ________ of chimpanzees (our closest living relative) has also been sequenced (2005) and is being compared to that of humans. [Note: The same word is used for both blanks] Q19. ________studied adolescent girls in Samoa and wrote up her observations in the 1928 book Coming of Age in Samoa. She concluded that adolescence in Samoa included sexual experimentation that made this stage less stressful for Samoan females than it was for American adolescents (providing a dramatic example of cultural variation). After her 1977 death, Derek Freeman (1983, 1998) challenged this conclusion based on his own observations that Samoa was a sexually repressive society. He concluded that _______ had been the misled by her informants who told her fanciful stories that did not match the reality. This challenge to a widely-accepted conclusion about Samoan culture sparked intense debate in the anthropological community. It demonstrated that new evidence could lead to doubts about a social science conclusion (just as new evidence can always be used to cast doubt on any natural science conclusion).
