Junius B. Smith, Weird Tales (1924)
“ He got up and crossed to a camera of which Bournette for the first time became cognizant. He focused it against one pale green-tinted wall, then waved a hand: "Behold! An ancestor of yours in the Stone Age, beating to death an animal for food. Observe the club he is using; note the skins he is wearing for protection from the elements; see the hairy arms and legs, the knotted muscles, the low, receding forehead. Your blood and his are the same." ”
