Mob (entity)

Humans are non-playable characters (NPCs) which take the form of clones of the default skin. They used to be created by pressing 'G' while playing in Creative mode, but this function was later removed. If the player has a custom skin, any humans created will still use default skin and will not assume the look of the player. Humans could not create or delete blocks, they would just move around the map aimlessly. They were affected by blocks and fluids the same way the player is.

Humans do not spawn in minecraft without using a map editor or mod.

Drops
Humans dropped nothing when added as a mob. Players drop all their items when they die, and Notch drops a Red Apple on his death.

Trivia

 * Notch originally made the human model to use in a top-down game called "Zombie Town".
