- 1. Why is it better to have evolution on organisms?1. There are two main groups of bats: Smaller “microbats” navigate by using sonar, and larger “megabats” rely on vision. Mammalogists once thought that both kinds of bats evolve from insectivorous mammals. But similarities between the visual systems of megabats and primates have led some researchers to think that megabats may have evolved from primates, perhaps lemurs. What results would support the hypothesis that the two groups of bats have a common origin? Separate origins?Evolutionary biologist Neil Shubin once said, "In one sense, evolution didn't invent anything new? It's using the old to make the new, and we call that tinkering." How does the concept of the evolution of the complex eye and the idea of exaptations support Dr. Shubin's statement? Explain and give an example.

Does evolution prove there is no God? No 5. Did humans evolve from apes? No1. Cells are the basic unit of life. 2. Genes are the basic units for passing traits from parent to offspring. 3. Evolution by natural selection is the process that has led to the great diversity of species on Earth. 4. Living things maintain the environment within their cells and bodies. 5. Living things have the ability to acquire and transform energy.1. WHY DO SCIENTISTS CONSIDER VESTIGIAL STRUCTURES EVIDENCES FOR EVOLUTION.

- WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.1. What is true of natural selection? The only way to eliminate harmful mutations is through natural selection. Mutations occur at random; natural selection can preserve and distribute beneficial mutations. Natural selection creates beneficial mutations. Natural selection is a random process. All changes saved11. Which of the following is NOT true: A. natural selection should favor the weeding out of harmful genes B. If changes to the DNA do not alter a gene's protein, they are more likey to get weeded out C. Scientists still aren't sure how DNA sequences results in a four dimensional animal D. There are more mutations and genetic differences between species BETWEEN genes than WITHIN genes 12.Whose discovery made the dating of ancient materials possible? A. Charles Darwin B. Francis Crick C. Marie Curie D. Gregor Mendel E. William Paley 13. Charles Darwin is responsible for discovering which of the following: A. the laws of inheritance B. the theory of natural selection C. the classification of living organisms D. all of the above 14. Sometimes a species' trait is not actually an adaptation because: A. it result from other properties B. hitchhiker effect C. it is an exaptation D. all of these 15.
