Different changes of DNa sequences Listen to the nature Mutation is bad and naturally repaired thus it could not be responsible for biodiversity. Recombination is good and naturally promoted; it is responsible for diversity inside of species Transposition is different from mutation and recombination because (1) producing mechanism is different: (2) no mechanism to correct it; 3) existing in nature in a well-controlled manner(10-5).
