What does childcare and nutrition have to do with fossil fuels?
They are all topics addressed in the book I am writing. I figured out a way a VR with our same rule-set could evolve without fossil fuel now and it was pretty simple really. Besides most large land animals not evolving at all there is no extinction event (hence the need for fewer people eaters because they would still be here) to give carbon based "stuff" (plants and empty bodies) the required environment to have been processed into fossil fuels in any large amounts so all energy would be developed without it. I'm just adjusting several variables and very cool stuff is falling out. Oh, this book was one I found as I have been researching ways to "mark" parenthood and birth date by developing different time keeping systems based on Reality rather than myth. I've almost got that figured out too. 142 pages. :)
