Which concept is best illustrated in the flowchart below?  \nA. natural selection  \nB. genetic manipulation  \nC. dynamic equilibrium  \nD. material cycles  \n2. The diagram below illustrates possible evolutionary pathways of some species.  \nWhich statement is a valid inference based on the information in the diagram?  \nA. Species A is the common ancestor of all life on Earth.  \nB. Species D is more closely related to species E than to species F.  \nC. Species B is the ancestor of species F.  \nD. Species C is the ancestor of species that exist at the present time.  \n3. Base your answer to the question on the diagram below, which represents possible relationships between animals in the family tree of the modern horse, and on your knowledge of biology.  \nOne possible conclusion that can be drawn regarding ancestral horses A and B is that  \nA. A was better adapted to changes that occurred during the Pliocene Epoch than was B  \nB. the areas that B migrated to contained fewer varieties of producers than did the areas that A migrated to  \nC. competition between A and B led to the extinction of Pliohippus  \nD. the adaptive characteristics present in both A and B were insufficient for survival  \n4. Base your answer to the question on the diagram below, which represents possible relationships between animals in the family tree of the modern horse, and on your knowledge of biology.  \nMiohippus has been classified as a browser (an animal that feeds on shrubs and trees) while Merychippus has been classified as a grazer (an animal that feeds on grasses) . One valid inference that can be made regarding the evolution of modern horses based on this information is that  \nA. Eohippus inhabited grassland areas throughout the world  \nB. Pliohippus had teeth adapted for grazing  \nC. Equus evolved as a result of the migration of Pliohippus into forested areas due to increased competition  \nD. ecological succession led to changes in tooth structure during the Eocene Epoch  \n5. The bones in the forelimbs of three mammals are shown below.  \nFor these mammals, the number, position, and shape of the bones most likely indicates that they may have  \nA. developed in a common environment  \nB. developed from the same earlier species  \nC. identical genetic makeup  \nD. identical methods of obtaining food  \n6. Information related to the organisms found on Earth during various geological time periods is represented in the chart below.  \nWhich statement concerning the first appearance of the organisms over the time period represented in this chart is most likely correct?  \nA. Life on Earth has remained the same.  \nB. Life on Earth has changed from primitive organisms to more complex organisms.  \nC. Life on Earth began with complex organisms and changed to more complex organisms.  \nD. Life on Earth has changed rapidly.  \n7. Which process is correctly matched with its explanation?  \n\n|  | Process | Explanation |\n| --- | --- | --- |\n| A. | extinction | adaptive characteristics of a species are not adequate |\n| B. | natural selection | the most complex organisms survive |\n| C. | gene recombination | genes are copied as a part of mitosis |\n| D. | mutation | overproduction of offspring takes place within a certain population |\n\n8. The information below was printed on a calendar of important events in the field of biology.  \n1859  \nDarwin Publishes  \nOn the Origin of Species by Natural Selection  \nThis information is most closely associated with  \nA. an explanation for the change in types of minerals in an area through ecological succession  \nB. the reasons for the loss of biodiversity in all habitats on Earth  \nC. an attempt to explain the structural similarities observed among diverse living organisms  \nD. the effect of carrying capacity on the size of populations  \n9. The Florida panther, a member of the cat family, has a population of fewer than 100 individuals and has limited genetic variation.
