Education-wise it is best to have an “uninteresting” cadaver to start with. Otherwise one might spend half a lesson trying to figure out something beyond their scope. But after grasping the basics it is best to delve into such variations, otherwise one might learn them mid-surgery.
For research it is best to have the test subject be as “normal” as possible (unless the research is about the variation), so the findings are not skewed.
