Dancing may hold clues to male physical strength
"Rated dance quality was positively associated with actual grip strength and these clues of upper-body strength were most accurately picked up by male observers. This ability to discern upper-body strength is principally because men are looking for cues of 'formidability' in other males," Neave said in a statement.
"Upper-body strength is highly related to fighting ability as it reflects the ability to do damage, especially in intra-sexual conflicts. The ability to gauge strength before potential conflicts is sensible, especially to other males," he added.
The study was published in the American Journal of Human Biology.
