Tree of the Knowledge of Good and Evil

The Tree of the Knowledge of Good and Evil was the tree in the Garden of Eden that God had commanded Adam and Eve to not eat from. The Bible gives no specifics on what type of fruit or other foods it produces; the only thing it says about this tree is that it gives "the knowledge of good and evil" to whoever eats from it. Adam and Eve are the only people to ever have eaten from it, and thus all of the human race has "the knowledge of good and evil". Upon Adam and Eve eating it, they realized they were naked and covered themselves.
