Although allen’s and bergmann’s rules most often explain body shape and morphology, we occasionally see variations from the correct patterns. this indicates that: a. the association between body shape, morphology, and the environment is not a result of natural selection. b. body shape and morphology do not reflect both evolutionary and developmental processes. c. the long-term association between body shape and climate is an example of acclimatization. d. the association between body shape and morphology does respond to environmental stressors.
