IBM World Book 2000 'Star':
[Quote/]Astronomers call the younger-generation stars Population I stars. They call the older-generation stars Population II stars. Population I stars are relatively new stars, such as the sun. They were formed from gas that had been part of earlier stars. Population I stars contain larger amounts of the heavier elements than do Population II stars. Population II stars are older stars that were formed from the first gas clouds in space. These clouds consisted mainly of hydrogen and helium, with much smaller amounts of heavy elements.[/Quote]
One set of options, the first ever set of options, A and Not-A, is created in the first generation. The first generation dies when it gives birth to the second generation. The second generation inherits the options of the first generation, and then adds to them. Thus two options become four options. This is repeated from generation to generation, each increasing the number of options by two fold. Each successive generation has more options than the previous generation. As it is with stars, so it is with humans. Societies, civilisations, technologies, mores, traditions, genetic inheritance and so forth. Each adding another set of options to the pile.
