Signs of intelligence

.....Over the last 25 years, biologists have discovered an exquisite world of nanotechnology within living cells—complex circuits, sliding clamps, energy-generating turbines and miniature machines. For example, bacterial cells are propelled by tiny rotary engines called flagellar motors that rotate at speeds up to 100,000 rpm. These engines look as if they were designed by the Mazda Corporation, with many distinct mechanical parts (made of proteins) including rotors, stators, O-rings, bushings, U-joints and drive shafts......
