the fine tuning is related with the training hypothesis and the common observation that play borrows actions from various contexts is the idea that while playing, an individual may be trying for an optimal goodness-of-fit of individual behavioral patterns in situations in which they do not have to pay severe consequences for mistakes; they experiment with different combinations of various behaviors that would never be tried under pressure. Fine-tuning gives behavioral flexibility, useful when conditions change. The ability to adapt with changing situations may be a skill that is necessary throughout life; it could facilitate the social integration of individuals into a group under different environmental conditions and increase success in catching different prey. In many species there appears to be strong selection against the continued addition of new motor patterns whenever something new is confronted. Thus, fine-tuning could evolve as an adaptive skill via selection for the ability to slightly modify existing motor patterns and the way in which they are linked sequentially in order to deal with changing situations.
