Which of the following is false concerning the evidence for evolution? Vestigial structures are a reduced structure or organ that was once useful to an ancestral species. The more closely related two species are, the fewer DNA base differences there is. In radiometric dating, fossils with more stable elements are younger than fossils with radioactive elements. Species that share a common ancestry will have homologous structures.

Below is a phylogeny depicting the relationship among eight animal species (A to H). Next to the species names are the tooth morphology of each species. For example, species A has prominent molar teeth, thus likely a herbivore. On the other hand, species C has prominent canine teeth, thus likely a carnivore. Which of the following statements is correct?       The most recent common ancestor for species A to H is probably a carnivore.     The most recent common ancestor for species A to H is probably a herbivore.     It is impossible to tell what the main food source is for the most recent common ancestor of species A to H.     For species C, D, E, F, G, there are four evolutionary events that lead to the evolution of canine tooth morphology.     IF the common ancestor of species C, D, E, F, G is a carnivore, then the molar teeth for species D is a plesiomorphy.

Explain the difference between macro and microevolution including how (or if) either (or both) are reflected in the fossil record.  Also, within your explanation provide examples of each. Explain the early ideas/foundations/paradigms of the theory of evolution.  Be specific and thorough with your answer. Describe the 'evolution of the idea of natural selection.  Be specific and thorough with your answer. Describe the conditions or circumstances when organic material (i.e. living things) would not be preserved.

Paleontologists at Grand Staircase-Escalante National Monument discovered a new ceratopsid skull. The skull has a moderate-sized neck frill, indicating a small body, and has two short horns. The table shows rock formations at the monument and the location of known fossils relative to those formations. Ceratopsid Fossil Locations Cretaceuos-Age Rocks MYA Formation Canaan Peak 70- Triceratops Torosaurus Kaiparowits 80- Centrosaurus Chasmosaurus Wahweap Straight Cliffs 90- Zuniceratops Tropic Shale Dakota San Rafael Swell 100 Protoceratopsid Based on the evolutionary relationship suggested by the anatomy of the skull, in which of the following formations was the skull found? Dakota Wahweap Kaiparowits Canaan Peak

Which of the following statements is correctly stated? Homology is due to ahared ancestry whereas analogy is due to convergentevolution. Analogy is due to shared anceatry whereas homology is due to convergent evolution. Homology is due to ahared biochemistry whereas analogy is due to shared molecular characteristics. Homology is due to shared morphology whereas analogy is due to shared molecular characteristics. S0000

Match the terms to their descriptors. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice. Two species evolve in different directions from a common starting point Divergent evolution Two species independently evolve similar structures Homologous structures Traits that look similar but were not inherited from a common Convergent evolution ancestor Analogous structures Traits that are similar because they were inherited from a common ancestor
