InTRODUCTIOn Evolution of behavioral responses is often dependent on the existence of modified structures that enable the development of the behavioral suite(Kay 1978;Lundrigan 1996;Alfaro et al.2004;Goyens et al.2015;Higham et al.2015;Sharp et al.2018;Schendel et al.2019).Occasionally,structural modifications are so important that a direct link between morphology and behavior can be inferred(Fleagle 1977;Rodman 1979;Losos 1990a;Higham et al.2015).
