 The nature of scientific explanation (see the entry on   scientific explanation)  in the literature on chaos is thoroughly under-discussed to put it mildly. Traditional accounts for scientific explanation such as covering-law, causal mechanical and unification models all present various kinds of drawbacks when applied to chaotic phenomena. For instance, if there are no universal laws lying at the heart of chaos explanations—and it does not seem credible that such laws could really play a role in chaos explanations—covering-law models do not look promising as candidates for chaos explanations.
