Human dance may have originated from selection to display quality in courtship. This proposal is based on comparative investigation of variation in motor skills in relation to mate preference and selection. However, scholars have also proposed that dance has evolved as a by-product of imitative proficiency. In this view, imitative proficiency plays a central role in dance learning and performance and facilitates movement synchronization among dancers and thus social bonding.Here we comment on a recent paper (Laland et al. in Current Biology, 26, R5-R9, 2016), which favors the latter perspective. We suggest that social bonding through dance has evolved in consequence of the adaptive problem of assessing mate qualities and other social information from body movement. This information may then have been used in strengthening social cohesion.Laland, Wilkins, and Clayton (2016) argue that human dance exploits neural circuity that evolved to facilitate imitation. In this view, dancing requires the performer to adjust his or her movements to an external or internal beat, thus demanding correspondence between an auditory input and motor output. Laland et al. therefore suggest that imitative proficiency is crucial in dancing, and may have been favored by selection to promote social learning. Laland et al. further propose that dance is an exaptation, a by-product of imitative proficiency. We argue that, in considering evidence from comparative research, this proposition prematurely dismisses the hypothesis that dance is an evolved display of motor skills and mate quality.In ritualized form, and especially with choreography, dance skills can be improved by imitation. However, this does not preclude the possibility that selection built sex-specific and condition-dependent dance-related adaptations to facilitate mating success. Research indicates that opposite-sex individuals are attentive to sex-typical mate quality characteristics, such as male strength and female fertility, conveyed through dance movements (Fink, Weege, Neave, Pham, and Shackelford 2015). Deriving these cues from dance movements of opposite-sex individuals does not require information about the dancer's ability to adjust to a rhythm. Yet, there is considerable variation in, for example, attractiveness assessments of male and female dancers, as predicted by Sexual Strategies Theory (Buss and Schmitt 1993), suggesting that dancing proficiency is a sexually selected adaptation.Dance is a complex physical, emotional, cognitive, and culturally ubiquitous social activity, characterized by intentional and rhythmic movements used to express many human facets, including sexuality (Hanna 2010). Comparative studies across taxa suggest that females select mates by evaluating male motor performance, along with conspicuous male ornaments (Byers, Hebets, and Podos 2010). Such elaborate displays are metabolically challenging and, therefore, provide honest signals of male vigor (i.e., the performance intensity of activities that require considerable energetic investment)....
