I do not think cavemen needed fire, unless of course everything was preplanned but undetermined. It is an interesting thought: a human society that develops without the accessory of tools. I think it is possible, but it would be so fragile.

To all your points about genetics: Edward Wirths, and all the accompanying links in the wikuhpuhDIEuh. I know they may not have known the were the early innovators, nor does their misguided research have a huge part in the modern attempt to begin refining our genetic structure in response to senescence and error. But their techniques are alive and well. If you don't treat the subjects like shit and you keep your mortality rates subdivided so they are not counted together, you can perform a buttton of research.

I know it does not need to come from war to be innovative. I personally believe that all inspiration comes from either fear or love. I think we as humans are exceptionally good at fear. I know i am shit at love.

I love your handle. I would love to talk further with you about some of those "other games".
