I find it really interesting that the bee’s stinger is a modified ovipositor (the thing they lay their eggs with). The theory is that the bee’s wasp-like ancestors laid their eggs into other insects so needed an ovipositor that could inject eggs into something quite solid. Over time the substances injected by the ovipositor became venomous probably because that made it easier for the bee’s ancestors to subdue the insect they were trying to inject eggs into (yucky!). But now bees don’t inject eggs into anything like that – but they still inject the venom, which is what stings, as Thomas said!
