... Chaos? ... One often looks toward physical systems to find chaos, but it also exhibits itself in biology. ... where r is the so-called driving parameter. ... Start with a fixed value of the driving parameter, r , and an initial value of x 0 . ... As one continues to increase the driving parameter, x n goes through bifurcations of period eight, then sixteen, then chaos! When the value of the driving parameter r equals 3.57, x n neither converges or oscillates its value becomes completely random. ...
