metadata.value: The anal organs (AO) of Drosophila larvae provide a textbook example of phenotypic
  developmental plasticity as they expand in low osmolarity conditions
  and shrink when larvae are reared on a high-salt medium. Waddington (1953)
  experimentally showed that these plastic changes might undergo “genetic assimilation”:
  the adaptive plastic change in the size of AO under high salinity
  conditions became hereditary after a few generations of rearing on a high-salt
  medium. Later attempts to replicate this finding produced ambiguous results.
  To clarify the question, we analyzed plastic osmolarity-related changes in the
  size of AO in three D. melanogaster lines adapted to low, intermediate, and high
  osmolarity during a long-term evolutionary experiment. We failed to replicate
  the genetic assimilation. However, we find that the reaction norm became wider
  in the low osmolarity adapted line. Additionally, we studied the fine structure
  of AO in fly lines using dying, SEM, and microtomography and revealed phenotypic
  plasticity of nanoscale pits on the surface of AO as well as confirmed the
  reduction of the epithelial cells of AO in flies adapted to higher osmolarity.
