- Discuss the validity of the statement “Evolution is an equal opportunity biological phenomenon”. Do you agree or disagree? Give examples that support or refute this statement.Discuss the significance of mutations and explain the role of the environment in the evolutionary process. (Hint: Consider Lenski's study and what is demonstrated. Do not re-tell Lenski’s study)Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question. Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________. What goes in the blank
- Why is it important to study evolution? Explain in three paragraphs.The following illustrations represent two different patterns of evolution. Briefly discuss the differences in these two patterns with regard to how evolutionary change (on the x axis) occurs with respect to time (on the y axis).Please use and cite any source(s) you can find to answer the following questions:1. Define "homologous structures," and explain how they help support evolutionary theory.2. Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificialselection? How is it different?3. For natural selection to work, there must be genetic variation within a population as well asmutations? Why must there be both?4. What is the difference between natural selection and sexual selection?
- Discuss at least two reasons why we cannot consider evolution by natural selection progressive.Briefly discuss the differences in how a selectionist (one that believes that Natural Selection is a strong evolutionary force) and a neutralist (one that believes that genetic drift is a strong evolutionary force) views the following: molecular clock, evolution of coding sequences, evolution of "pseudogenes".Find two examples in the media (internet, TV, etc.) of someone (organization, etc.) erroneously portraying Darwinian evolution using a Lamarckian approach. For both, provide the following: Its origin How are they misrepresenting Darwinian evolution? How do you know they're talking about Lamarckian evolution, not Darwinian?
- Most of the time, evolution seems to do a pretty good job of turning out living organisms with adaptations that help them survive and thrive. But sometimes it doesn’t entirely seem to make sense, or intriguing at the very least. In other words, evolution can fall well short of perfection. Add to the images above at least 2 examples of such "mistakes of evolution." Briefly explain how evolution screwed up in each case.
