50 things every biologist should know

Hi, Parasite members.  Like many Biology departments in universities across Canada, our university, the University of New Brunswick at Saint John, has decided to phase out the comprehensive exam in favour of a proposal defense/qualifying exam as part of the requirements for completion of a Ph. D.  The rationale for this, as we understand it, is that students should not be expected to have a detailed understanding of the entire discipline of biology.  A proposal defense/qualifying exam is only expected to test a student on areas relevant to their Ph. D. research.  This is a concept we support, but it does raise the concern that students could graduate with a Ph. D. in Biology without understanding some very basic biological concepts if those concepts are not relevant to their project.  For example, students doing research that has no explicit evolutionary context could graduate without knowing the difference between evolution and natural selection.  Our discussion group has suggested that one way to deal with this is to develop a list of ‘The 50 things every biologist should know’ and make those 50 topics fair game in a qualifying exam/proposal defence.  Thus, our goal is to put together such a list.  We have put together a preliminary list of 60 different questions (maybe) every biologist should be able to answer (see that list below), but we are looking for broader input.  We would love to hear from anybody who would like to add a question or questions to the list, or make some comment about the questions that are already on the list.  Ultimately, we will be putting together a survey to rank the suggestions we get and identify the ’50 things every biologist should know’ as ranked by survey responses.  We will distribute that list to this group when the survey is complete.  Thanks for any comments you can provide on this.
