Pathways of developmental plasticity: Since none of the pathways are mutually exclusive and many pathways could be operational simultaneously, rather than any dichotomous classification, a path analysis approach or multiple predictions approach would work better for empirically testing the phenomenon. The developmental-activational plasticity is a continuum rather than a dichotomy and evolution along this continuum would depend upon the cost of reversing the phenotype versus the possible loss by mismatch
