1 Evolution and Controversy

2 Evolution and Health

3 The virus If a person is infected and survives, they will have life-long immunity. If a person is infected and survives, they will have life-long immunity. They can steal genetic code from other viruses They can steal genetic code from other viruses Always seem to be at least one step ahead of everything Always seem to be at least one step ahead of everything

4 The Flu Influenza (flu) is a respiratory infection in mammals and birds. Influenza (flu) is a respiratory infection in mammals and birds. Rapid evolution of the influenza virus Rapid evolution of the influenza virus A zoonosis is an infection or infectious disease that is transmissible from vertebrate animals to people. A zoonosis is an infection or infectious disease that is transmissible from vertebrate animals to people.

5 The Swine Flu It appears the H1N1 swine flu may be a reassortment of the H (hemagglutinin) gene from typical North American pigs with the N (neuraminidase) and M (matrix) genes from European pigs It appears the H1N1 swine flu may be a reassortment of the H (hemagglutinin) gene from typical North American pigs with the N (neuraminidase) and M (matrix) genes from European pigs If so, this new virus is an example of the importance of recombination in evolution. If so, this new virus is an example of the importance of recombination in evolution.

10 Scientific Creationism Movement Creationism is just as much a science as evolution and evolution is just as much a religion as is creation. Creationism is just as much a science as evolution and evolution is just as much a religion as is creation.

11 Intelligent design Alternative to evolution. Alternative to evolution. Life is too complex for natural selection and must reflect intelligent design. Life is too complex for natural selection and must reflect intelligent design.

12 Why ID and CS are not in science class Explanations that cannot be tested and potentially rejected are not science. Explanations that cannot be tested and potentially rejected are not science. If someone invokes a nonnatrual cause in their research, and you decided to test it, can you think of any way to do so such that it could be falsified.

13 What do you think? About creation science and intelligent design being taught in science class? About creation science and intelligent design being taught in science class?
