Question 5: Give us your thoughts (2 points total)

A) Choose one of the six quotes listed above, and tell us whether you agree or disagree with it based on what you have learned completing this report, and why.

(1 point: maximum suggested length = 100 words)

B) From your research, do you think aging is inevitable, and is this a positive or a negative? (As an aside, an interesting novel entitled “2030” by Albert Brooks is set in the future where most diseases such as cancer and Alzheimer’s have been cured, the world population is skewed towards old people, and explores the social consequences that ensue. Please note it is NOT required that you read this book – but it is fun!)

General Instructions This essay should be 400-500 words in length. You must use correct spelling and proper mechanics. You must include citations and a reference list for any resources used at the end of this essay. It is expected that you will use one to two references for this essay topic. Essay #2 Studies of identical and fraternal twins have yielded some very interesting information on the genetic basis of behavioral traits. Read both of the following articles from the web, and then complete the assignment below. · Do our genes make us popular? From Scientific American http://www.scientificamerican.com/article/popularity-genes/ · Minnesota Study of Twins Reared Apart, from the Minnesota Center for Twin and Family Research http://mctfr.psych.umn.edu/research/UM%20research.html Address the following questions in your essay: · What is most striking to you in the results presented in the two articles? · In the article on popularity, do you agree with the conclusion that there is a genetic basis to how popular people are? Explain why or why not. · In the twin studies, do you think that the behavioral similarities in identical twins raised apart from birth (like “the Jim Twins”) are due to inheritance? Explain why or why not. · Conclude by stating whether or not these two articles have changed the way that you think about genetics, and explain your answer.

An adaptation or adaptive trait is a trait/characteristic that has evolved in a population of organisms which provides a functional advantage. Adaptations increase the biological fitness of a population. Fitness is defined as the ability to survive and pass genes on to subsequent generations. For the purposes of this assignment, you are to choose an adaptive trait common to more than one species. For example, birds and bats both have wings. Write a 2-3 page (500 – 750 words, 12 point font) paper including the following elements. Be sure to compose your work with your own words. Do not copy and paste from any source. Describe what makes this trait an adaptation. Briefly describe how the trait evolved; e.g., mutation, genetic drift, migration and/or natural selection. Be sure to support your answer with evidence. What is the difference between homologous and analogous traits? How does your trait of choice fit either of these descriptions? What is convergent and divergent evolution? Describe whether the trait is a result of convergent or divergent evolution. Use in-text citation and provide source references for at least 3 sources. The textbook can be one source. When citing articles or other types of documents, follow standard guidelines as introduced on "Citing references in scientific research papers".
