Comment on 'Parasite defensive limb movements enhance acoustic signal attraction in male little torrent frogs'.

Zhao et al. recently reported results which, they claim, suggest that sexual selection produces the multimodal displays seen in little torrent frogs ( Amolops torrentis ) by co-opting limb movements that originally evolved to support parasite defense (Zhao et al., 2022). Here, we explain why we believe this conclusion to be premature.
