Answer :
Behavioral evolution may involve evolution of anatomical, sensory and brain to carry out a behavior. Behaviors have genetic background. Behaviors are among most complex phenotypes. eg:- detailed analysis of schooling differences in marine and freshwater stickle backs revealed multiple distinct behavioral modules that had evolved to reduce schooling in freshwater sticklebacks.
Many studies showed a potential link between neuronal and genomic architecture of behavioral evolution. Targets of behavioral evolution span between detection of stimulation through production of behaviour. Broadly behavior can evolve through 4 different process a. Sensory perception b. Threshold to respond to a stimuli. c. Template for behavioral output. d. Morphological effectors of behaviour.
