The Characteristic Of Honey Bee

Honey bees are a subset of bees in the genus Apis, primarily distinguished by the production and storage of honey and the construction of perennial, colonial nests out of wax. Honey bees are the only extant members of the tribe Apini, all in the genus Apis. Currently, there are only seven recognized species of honey bee with a total of 44 subspecies though historically, anywhere from six to eleven species have been recognized. Honey bees represent only a small fraction of the approximately 20,000 known species of bees. Some other types of related bees produce and store honey, but only members of the genus Apis are true honey bees.
Honey bees as a group appear to have their centre of origin in South and Southeast Asia including the Philippines, as all but one of the extant species is native to that region, notably the most plesiomorphic living species. The first Apis bees appear in the fossil record at the Eocene-Oligocene boundary, in European deposits. The origin of these prehistoric honey bees does not necessarily indicate that Europe is where the genus originated, only that it occurred there at that time. There are few known fossil deposits in the suspected region of honey bee origin, and fewer still have been thoroughly studied. There is only one fossil species documented from the New World, Apis neartica, known from a single 14 million year old specimen from Nevada.
The close relatives of modern honey bees like bumblebees and stingless bees are also social to some degree, and social behaviour seems a plesiomorphic trait that predates the origin of the genus. Among the extant members of Apis, the more basal species make single, exposed combs, while the more recently-evolved species nest in cavities and have multiple combs which have a great facilitated their domestication.
Most species have historically been cultured or at least exploited for honey and beeswax by humans indigenous to their native ranges. Only two of these species have been truly domesticated, one at least since at the time where the building of the Egyptian pyramids and only that species has been moved extensively beyond its native range.
