(B) The excessive use of herbicides and pesticides has resulted in the selection of resistant varieties in a very short period of time.This phenomenon is also observed in microorganisms against which we use antibiotics or drugs.Consequently,resistant organisms or cells appear in a very short time,i.e.,within months or years,rather than centuries.These are examples of evolution by anthropogenic action,which also indicates that evolution is not a directed process in the sense of determinism.It is a stochastic process based on chance events in nature and chance mutations in organisms.
