I've never really paid much attention to that, though there is certainly a divide within the department (mostly because I've been pretty deeply entrenched on the critical side of things). I am fairly certain that the med anthro profs choose the incoming med anthro students, if that helps any... Oh, and I will say this- disregarding the internal politics and divides within the department for a moment, all of the faculty are well versed in each other's work, and certainly recognize a good match between faculty and student when they see one.
