Bees

Introduction

The monophyletic status of the bees shared by numerous derived characters (synapomorphies) and considered the undisputed evidence. Also, undisputed is the close relationship of bees to the grave wasps. For a long time regarded both groups as sister groups to the grave wasps as prophylactic were detected. “Honey bees are insects belonging to the phylum insecta,” (Shaw, 2012, pp 34). Matching would be the inclusion of the bees as one family among several families' grave wasps. On the other hand, has the distinction established in the bees of several families long ago (Mandeville, 2011, pp 37). By significant differences in physique appears this is justified, and further subdivisions based on lower taxonomic levels. A compromise, proposed by leading systematizes of the group includes, among the super family Apoidea families of wasps and bees grave in two series (and Spheciformes Apiformes) together (Shaw, 2012, pp 39).

Discussion and Analysis

In the summer, a single hive may contain bee's ranging from about 40,000 to as many as 70,000 (Ribiere, Olivier & Blanchard, 2010, pp 124). Most of them are workers. They are female bees, but the remaining ovaries. Each state has only one queen bee. It has developed from a fertilized egg to the only female that has a complete reproductive system and can lay eggs. It ensures that for the nation's survival. Clearly visible on her plump body with the rounded abdomen, are the drones. They are the male bees, which are derived from unfertilized eggs (Mandeville, 2011, pp 37-38).

Development History

Today bees on flowering plants, the angiosperms (angiosperm), instructed in the earth in the early Cretaceous period and emerged since the late Cretaceous period, the gymnosperms and vascular cryptogams repressed (Mandeville, 2011, pp 42). Flowering plants from the period before about 110 million years ago are already showing characteristics that suggest a close pollination by bees, the origin of the bees is thus probably even before the mid-Cretaceous. Perhaps, these plants were once common but even that cannot be detected by lower volumes produced pollen (Shaw, 2012, pp 37-39).

Today's most primitive flowering plants are pollinated by bees, it is therefore reasonable to assume this as a pollinator of the first Cretaceous flowering plants. In the course of tribal history, but bees and flowering plants jointly developed and supported each other: While the bee pollen from plant to plant further contributed, they improved their chances of reproduction. The plants began to adapt to it and developed sweet juices to bind the animals. Over time, fit both bees and flowering plants, more and more together to (co-evolution), the plants developed their modern flower shapes with deep nectar cups and stamens, the bees their long proboscis to look good on the nectar get hold, and it specifically to pollen transport custom coat (Michener, 2012, pp 15-18).

The bees feeding on wind-pollinated by pollen indigenous plant are uncertain, however, been suggested on several occasions. The oldest fossil bee is Trigona prisca called and was embedded in amber in the American state of ...
