Dear A.D. Karve: Are you suggesting that it was the invention of "smooth roads" that spurred the subsequent invention of the wheel?
The indigenous peoples of the American Great Plains were migratory and dragged their possessions on high-friction sledges. The "Pioneers" of the mid-19th Century had wheeled conveyances and followed "trails" not macadam. Wagon Trains. The Spanish who conquered the great Inca empire had wheels, an unthought-of notion to indigenous cultures over 10,000 years old. Why didn't Nature provide hummingbirds with a rotary wing? Rolf gave a good clue. Best, Mark Best, Mark >> Dear List, >> I am neither an engineer nor a physicist, but a biologist.
