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 …show more content…
The chemicals possessed by a fly on their surface are called cuticular hydrocarbons (or CHCs) and their scents will differ and be dependent on the mix of the cuticular hydrocarbons. One scientist contributes a quote of exactly how to think of cuticular hydrocarbons, “It’s as if each fly has a bouquet of flowers it’s holding” (Kwok, 6). The hydrocarbons that flies sniff will help them choose a mate, which leads the scientists to think that there is a chance that the flies mated with the ones they did because the bacteria changed what cuticular hydrocarbons were made from each fly. In order to find out what had happened, the scientists used a mutant fruit fly that was unable to make cuticular hydrocarbons. Because these flies do not make cuticular hydrocarbons, they do not care about who they mate with. Infact, these mutant fruit flies cannot tell the difference between male or female. The research scientists continued with their study by creating special scents and extracting cuticular hydrocarbon from some starch flies and some molasses flies, and then coating the mutant flies with hydrocarbons from the starch and molasses. The scientists decided to take the mutant flies and ordinary starch and molasses flies to mate. Although the research is not yet complete, some early results prove that the flies like to mate with each other and anyone sharing their …show more content…
In the article, the author was trying to determine how bacteria impacts the scent of two different groups of fruit flies, and whether or not the scents would have a role in mating, “Rosenberg’s team suspected the answer might lie in chemicals called cuticular hydrocarbons (CHSs). These chemicals cover the surface of the fly. A fly’s scent will differ depending on its mix of CHCs. Explains Sharon, it’s as if ‘each fly has a bouquet of flowers it’s holding’” (Kwok, 6). To me, chromatin relates to the cuticular hydrocarbons because in the same way that cuticular hydrocarbons determines the scent of the organisms, the chromatin of a cell can determine certain genetic information. Additionally, both chromatin and cuticular hydrocarbons contain aspects that provide a unique component to organisms. Chromatin shows that all people cannot have the same DNA (with the exception of identical twins or triplets) and will have different characteristics, just like cuticular hydrocarbons can determine the different smells that flies may have. The characteristics that chromatin and cuticular hydrocarbons have can determine some things when mating. For example, the scents of cuticular hydrocarbon causes flies to choose their mate, “Flies sniff each other’s CHCs when choosing a mate” (Kwok, 6). In the
