Applying a molecular clock: the origin of hiv. Is descended from viruses that infect chimpanzees and other primates. How did the virus get from chimps to humans: bush meat trade is the usual hypothesis, hooper suggested instead, that early polio vaccines may have been created using chimpanzee cells, a possible source of hiv. This would have occurred in the late "50s. Independent evolution of similar assemblages of fish on each continent: long distance (across ocean) dispersal brought similar forms to each continent. Vicariance (splitting by geographic barrier): similar fish found on each continent because the separation of the continents split populations. Pairs of similar fish on different continents diverged much more recently than the continents split apart. In january, 1995 janet allen, a lafayette, louisiana nurse tested positive for hiv-1. Schmidt, a local gastroenterologist of infecting her with hiv and hepatitis c. Schmidt himself was not infected with either disease.
