Beneficial Acclimation Hypothesis: A Commentary

Divya Singh, Seema Ramniwas*

Evolutionary adaptation to climate change by an individual within its lifespan gave rise to a trait known as phenotypic plasticity which allows phenotype of individuals to 'fit' in changing environments. Phenotypic plasticity is a type of developmental plasticity because an organism during its life span when anticipated by external environmental or internal physiological factors, adopts a permanent physiological, morphological, or behavioral change in the developmental trajectory through gene–environment interactions. [1] Plasticity and acclimation is the most common response which becomes evident at physiological level as well as at the morphological level to environmental change. To describe the assumption that all acclimation changes enhance the physiological performance of an individual, the beneficial acclimation hypothesis (BAH) was proposed. [2, 3] BAH especially in response to environmental variation have focused on plasticity. BAH is contentious with robust criticism and multiple hypothesis assessed it.
