6 bees phylogeny reachs group genetics
Carry the preliminary research of information of pair of apian gene group, can offer about apian origin and this species the pertinent information of the transmission inside alive bound limits, can support the hypothesis of completely abnormal insect with Hymenoptera insect inchoate traceable, challenged think to compare beetle now kind the viewpoint of differentiation evening. And reach the cent division of apian division antedates the time that nowadays thinks, these evidence originate the fossil of the earliest bee (Melittosphex Burmensis) , in the discovery in the amber sample of Burmese north, before be 100 million years (namely the Cretaceous age is inchoate) , they are had a few kinds of features of the bee and shape structure include biforked wool now, researcher thinks this is planted wool and collect pollen to concern.
Gene constituent analyse still makes clear, apian ancestor and human ancestor come from Africa euqally. Scientists think, the oldest bee comes from a the Sahara with south, pass change sentence twice later, distributing stage by stage Eurasia each corners, produce the evolution that fits local requirement, but twice this change apprentice also happens in a long time ago. Ability comes to America after 17 centuries, exotic plants the “ that be called the wonderful example ” that inbreak. This one discovery broke through the traditional point of view of apian traceable Eurasia.
The bee has important pollination to use value not only, bee product also is the friend of human health, more important is the bee has ability of breathtaking study, memory, navigation and complex sociality action, the bee already became the nerve biology such as study, memory, navigation to study the good model of the domain, its are complex the mechanism of sociality behavior and the strategy that answer surroundings are sure to offer beneficial edificatory to the development of human society. Immune system of the bee and macrobian mechanism research will be disease of human allergy, spirit, long life and X chromosome the research of relevant disease provides new model. The finishing mark that apian gene group measures order is worn times of form of the gene after bee learns to consider to enter, the research of gene function and adjusting control mechanism will become new heat.
