It had been regarded as inevitable and universal that adolescents would confront the difficult/stressful period, so called “ Storm and Stress”, in early developmental psychology. However, recent studies have been suggested that it is not inevitable and universal, but more likely that adolescents could pass through the “Storm and Stress” period. In addition, there are substantial individual differences. There are three components in adolescent's “ Storm and Stress ” . Recent evolutionary approach for adolescent social/emotional development has been dealt with two of them, risk behavior and mood disruption, and revealed the reason that adolescents would likely confront difficult period and also indicated the factors that contribute to individual differences. In this paper, it is discussed that the effectiveness of evolutionary approach, especially life-history theory for social/emotional development toward the remaining one, conflict with parents. And then, it could indicate that whether adolescents experience the "Storm and Stress" period and its severity represents the emerging individual reproductive strategies which adolescents attempt to maximize their fitness in each environments, with their own ability/traits.
