Rotary Engine Technology in Living Cells

Gone are the days when evolutionists asserted that life would never produce wheels or gears. It was impossible, they thought, for structures like that to arrive by natural selection, because too many coordinated mutations would be required. A wheel without an axle would provide no fitness advantage. One gear could achieve nothing without a matching gear. That was before we learned about the planthopper with its gear-driven jumping feet and the exquisite rotary engines of cells: the bacterial...
