Use a piece of tracing paper to trace the square and the outline of a human ear in the following picture. Add a square first to the top of the square shown, then to the left, and then to the bottom. Note that the length of the side of the square added at each step increases and is equal to the length or height of the rectangle in the previous figure. Then draw in quarter circles, beginning in the lower left corner of the original square, to form a spiral. Does the human ear form a Fibonacci spiral?
