Assignment:
Question 1. Some critics of Darwin's theory of evolution by natural selection have claimed that the concept of natural selection is tautologous (i.e., it is a vicious circle). They say, Natural selection is the principle of the survival of the fittest. But the fittest are defined as those that survive, so there is no way to prove or disprove the theory. Argue against this statement, based on genetic drift and Neutral Theory of Molecular Evolution.
