The Second Act
The second act began only about ten thousand years ago. A few of the players started it by themselves near the center of the Old World part of the stage, in the Near East. It began as a plant and animal act, but it soon became much more complicated.
But the players in this one part of the stage—in the Near East—were not the only ones to start off on the second act by themselves. Other players, possibly in several places in the Far East, and certainly in the New World, also started second acts that began as plant and animal acts, and then became complicated. We can call the whole second act The Food-Producers.
