SCI 115 Week 7 Discussion STR
Select one of the following three topics for your primary post. In a primary post of at least 125 words, address the issues listed in the instructions. Also, make a substantive reply to a fellow student on any subject.

Topic 1. Co-evolution of rattlesnakes and squirrels. Read at least one of the following articles (1)* and/or (2)*. Please address the following questions: (a) How do squirrels adapt to rattlesnake venom? (b) How do rattlesnakes adapt to squirrel’s defenses against rattlesnake venom? (c) What do the results of this research tell us about evolution?

Topic 2. Climate change and Bergmann’s rule. View Dr. Cox’s video (3)* on climate change and Bergman’s rule (10 minutes) in the Instructor Insights folder for Week 7. Then, address the following issues: (a) Describe three things you learned from the video. (b) Explain what type of evidence you would accept as evidence of genetic evolution in response to changing climate conditions.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
