1.) Which questions by a student would lead to a better understanding of the difference between the theories of Darwin and Lamarck? Which scientist's theory came first? Which scientist’s theory requires genetic diversity? Which scientist’s theory involves the inheritance of useful traits? Which scientist’s theory involves change in organisms over time? Explain your choice. Darwin’s Theory of Natural Selection states that there is a struggle to survive as organisms compete for resources and try to avoid predation. Over time, the organisms best adapted will survive and pass their traits on to offspring. Which of the following is the best explanation of the role mutations play in natural selection? Mutations provide variation within a population and environmental pressures select for or against these adaptations. Mutations are always harmful and organisms with mutations will be selected against, leaving those that are best adapted to pass their traits on to offspring. All mutations in somatic cells are passed on to offspring and over time as mutations are passed down through generations, populations will change. Mutations that occur in gametes are always fatal to offspring which prevents new traits from entering into a gene pool.

Expert Solution

Answer

Evolution is the change in the characteristics that are acquired over generations and will lead to new species. There are three types of evolution: divergent, convergent and parallel evolution. There are various theories of evolution: Lamarck's theory, Darwin's theory and De Vries theory.
