You are working in a Natural History Museum and an intern has mixed up the labels from three skulls: a lemur, a New World Monkey, and an Old World Monkey. What single feature would you use to determine which skull belongs to which label?

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
