WtP -“In these days of computer simulations, I wonder why it is even necessary for most people taking science courses to do any animal dissections- can’t it be done virtually? How many of these students will actually need that sort of experience for their actual careers? Med students will dissect cadavers in med school, that should be enough.”
You need animal dissection because there aren’t enough cadavers! A lot of medical courses have gone the computer simulation route.
