ESSAY/SEMINAR TOPICS Biol4130.03

Below, I list a number of topics and a paper that will form the starting point of your essay and seminar for this course. I have somewhat loosely categorized the papers (in bold face headings). You should choose one paper from the list for your seminar (or if you like you can pick a paper not listed below, but you must have my approval if you wish to do this). Your essay should more broadly cover the subject matter related to the paper but the seminar can be more focussed on just 1 or possibly a small number of papers.

Please choose a seminar topic by next Wed Oct. 16. If you haven't, I will assign an essay topic.
