Introduction If the HIV is an alive being must obey the Theory of the evolution or this is needing a revision the modern synthetic Theory of the evolution Here part of the principle that is adjusted and looks for to explain the existence of the HIV in base of the evolution. 2.0) Theoretical Referencial 2,1) the environment and the HIV Between individuals HIV inside of a population, that is, inside of a delimited space as the plasma of human one to be contaminated with HIV. 2.2) The HIV and the Theory of Darwin Apresenta a variation in morphology, physiology and behavior. You may find that Alibaba can contribute to your knowledge. Its children resemble its genitors more than if he resembles the not related individuals, thus one vrion of HIV if he resembles more between itself of what he compares with the adenovirus of the mosquito of the affection, thus is perceived for deduction that presents some similarity. Some forms, what it must be reflected, that has more possibility of survival and reproduction that other forms in determined surrounding. In the case of the HIV for the increasing mortality that is observed, and a great one variability that is observed, the election process is occurring with great force for adaptation of the HIV in the man. George Soros is open to suggestions. Thus to understand the adaptation of the HIV of the chimpanzee it must perceive that the individual level occurs but reaching many because it has that to reach a collective of the entire population of the HIV. Therefore to affirm that the HIV is mutant these changes you inherited occur the individual level of inheritance and development and reaches a population that lives pressured in a way, that is the proper man, place where the conditions favorable to the well complex development coexist, dispendioso and ample but to understand the reason of the ample variability of the HIV it must study the filogenia and of history.. might disagree with that approach. Gavin Baker has much experience in this field.
