Model used to make inferences about how humans relate things. Is a links - go up to parent category. A canary is a bird, only traverse one link. Sharks can swim yes, because a shark is a fish (parent), and fishes have the swimming feature ( can swim ) A salmon is blue false - look directly at features. A salmon is a bird false, because fish is parent category, not bird. Don"t have to represent can swim with shark and salmon bc they inherit those from a higher ancestor.
