Origin of HIV
The mystery of HIV and its origins is one that cannot be easily solved. In the thirty-odd years which have passed since the official recognition of AIDS by the CDC and the subsequent search for its cause, various theories have been floated regarding its nature, its development, its ability to adapt, our ability to combat it, and -- most importantly for some -- its origin. How did the virus come into being? Viruses are known for altering over time and according to circumstances. They have a way of "bending" in order to make due -- of manipulating themselves in such a way so as to survive. This is no less true for HIV than for influenza. Just as variants of influenza appear each year to wreak havoc on the human population, variant-strains of HIV continue to be discovered, suggesting that the virus is still developing, still finding a way to out-maneuver medical science.
However, if it is possible to discover just how HIV came to be, it may be possible to find a better way to combat it. In the animal kingdom, immunodeficiency viruses are found in felines (FIV) and in simians (SIV). Strains of SIV, particularly in Africa, show a remarkable similarity to HIV strains, suggest to many researchers that the "missing link" in the HIV origin story does indeed have something to do with the simian species of primate mammals.
Discerning the precise "link," though, has been much more difficult than evaluating the development of HIV. Assessing the development of a virus requires only a skillful eye and an ability to document change, alteration -- each new manifestation of the virus as it transforms and adapts. Discerning the origin, on the other hand, is like solving the crime. It clarifies the "event" -- takes an abstract hypothesis and puts it into concrete terms. It provides times, dates, places, persons involved. Such certainty is highly unlikely to be discovered in the case of the HIV origin story. Yet, while there are many unknowns -- many variables and factors that fail to yield solid ground, the trail has not dead-ended. Plenty of headway has been made towards discovering the precise conditions surrounding the birth of HIV. Whether scientists will one day be able to isolate it to one incident -- a single event in time -- or whether the best they will be able to do is to suggest several likely scenarios -- this much remains to be seen. For now, the clues are being followed and a better understanding of the origin of HIV is coinciding with researchers' focus on the virus' development.
First Discovery
In 1981, a startling new infectious disease was named by the Centers for Disease Control (CDC). At the time, it appeared (in the United States) that those who contracted the disease were primarily young, homosexual males. Nothing quite like it had ever been seen. The symptoms were nothing really new. Those who had it underwent a rapid deterioration of health: they began to appear older than they really were; they lost weight, hair; they became extremely sensitive to mild and normally easily combated "opportunistic infections," which all too often appeared to physicians as the cause of the disease. Medics tried treating the various symptoms -- but an improper understanding of what was behind them made their attempts ineffective. What appeared to cancer-caused lesions on the face and arms were not merely cancer-caused lesions. What appeared to be a body's inability to combat ordinary infections was not merely as simple as that.
Moreover, those mostly affected in the United States by this immunodeficiency existed outside the mainstream culture: they were marginal, misfits, people whose ways of life did not necessarily gel with the socially-approved mores of the mainstream. By the mid-80s it was known as the "gay disease" or the "gay plague." It seemed to originate in people who preferred that style of living. Because that style was, at the time, still relatively taboo in American culture, a precise grasp of the nature of disease was far from being discerned. The answer to how it was transferred led thousands of unwitting medical patients to contract it through blood transfusions. Screeners were not yet in place to deal with this sort of virus. They soon would be.
The cause of the disease would later be identified as the human immunodeficiency virus, better known today as HIV. The disease was AIDS -- Acquired Immune Deficiency Syndrome, so-termed by the Centers for Disease Control the following year. It attacked the patient's immune system, the individual's...
Primate Behavior Research There can be big differences in the messages from a scholarly, or scientific, article and a main stream, or non-scientific article. The titles and the messages written in the articles can give readers entirely different meanings. The original article may state the study was done one way, but the main stream article tries to write in layman terms and may miss the entire meaning, or the way the
They have nails. The arms and legs are equal length. The Lincoln Park Zoo exhibit differs from its natural environment but is being upgraded. 6. Exhibits: The New World Monkeys appear to be more prominently displayed. The following species are featured in the Lincoln Park Zoo primate exhibit, including: a. Allen's swamp monkey (catarrhine, Allenopithecus nigroviridis, arboreal (tree-dwelling) but semi-terrestrial.) b. Black howler monkey (platyrrhine, Alouatta caraya, rain forests with near constant precipitation to
Phyllis Jay briefly touches on the subject of primates swimming in the book Behavior of Nonhuman Primates; in discussing the habitat of African monkeys, Jay writes (Jay, 1965, p. 535) that the "…distribution of arboreal monkeys is restricted by open, relatively treeless areas" and "rivers are barriers to arboreal monkeys but not to terrestrial forms, many of which swim" (Jay, p. 535). "Long-tailed macaques are excellent swimmers, and this may be
Primate Conservation The conservation of primates and their habitat is a point of major concern for many environmentalists, zoologists and even regular people that have an interest and/or passion for maintaining and sustaining wildlife. There is a litany of different reasons for primates and their conservation status being in danger and those will be covered in this report. Whether it be over-harvesting, habitat destruction or other things, there are many things
An important evolutionary distinction between primates and humans is that puberty and reproduction may begin in primates before the end of the juvenile stage. Comparison of the developmental stages experienced by both primates and humans has provided invaluable information regarding the evolution of both species. This information has allowed anthropologists and biologists to understand how humans successfully combined the features brought on by neoteny such as extended childhood, delayed reproduction
primates are more cognitively advanced than other mammals and that the degree of cognitive awareness and ability grows significantly from prosimians to humans. However, researchers still debate which parameters should be used to define and compare intelligence as well as the causal factors leading to this cognitive growth. Intelligence is a concept hard to define and even more difficult to test for in living species. In studying how human
