ting who organisms will mate with, as shown in the paragraphs Sniffling out a mate, and Fly Perfume. With the ability that bacteria has on mating, it is possible to extend and create a whole new species. When it comes to mating, organisms usually prefer to mate with an organism similar to them. The author believes that a major change with a species could happen because of preference, and natural boundaries. One example of this can be found on page five, “Over time, two isolated groups of a species could each change in unique ways, eventually creating separate species” (Kwok, 5). Researchers prove believe it is possible that microbes may trigger the formation of a new species. In a study conducted by a husband and wife in Israel, one groups of fruit flies were fed starch, and another group of fruit flies were given maltose. The scientists figured out that the population of flies fed starch only wanted to mate with other who ate starch, while the flies that ate maltose only wanted to mate with other flies that ate maltose. In order to see what would happen when a “maltose” fly mated with a “starch” fly. The scientists of Israel realized that the first thing they needed to change was the microbes. If the scientists were to change the microbes in the gut that could sucessful break down new food, they think they might cause these microbes to multiply. Additionally, these microbes may be able to produce new bacteria that would change an animal’s scent by producing chemicals,…
