Pincer plot twist: How female earwigs evolved deadly claws for love and war

Female earwigs may be evolving exaggerated weaponry just like males. A study from Toho University found that female forceps, once assumed to be passive tools, show the same kind of outsized growth linked to sexual selection as the male's iconic pincers. This means that female earwigs might be fighting for mates too specifically for access to non-aggressive males challenging long-standing assumptions in evolutionary biology.
