You mean honeybees? Because there are lots of other (wild) bee species that are very specialized. And they also contradict most of the other things we think we know about bees: they are usually solitary, and they rarely sting (honeybees only do that to protect the hive).

Maybe it's the other way around: humans selected honeybees to "domesticate" because of their versatility (and of course the fact that they produced honey)?

Around my location (southern brazil) there are hundreds of species of stingless bees, living in colonies. Many (most?) produce honey too. I don't dispute that there are also lots of solitary bees. Bees are wonderful and way more diverse than people usually think.
