I and most likely you were taught at school or even University that nature has never invented the wheel. I have just discovered that it indeed nature did invent the wheel. Not only that bu the wheel may well have been one if not the very first locomotor device ever evolved. Types of bacteria use thread like spiral propellers each driven by its own continuously rotating propeller shaft.. This flagelum is attched to the shaft tat rotates freely and indefinitely in a hole that runs through the cell wall. This is a true axle. Probably been around for 2 billion years... truly astonishing!!!
