Mechanisms of Cellular Development in Maya Pines' Learning in the Worm Maya Pines' Learning from the Worm is highly insightful and well written. Simply speaking, the article confronts the mystery behind the mechanisms that works during cellular development. Scientists were split over the kind of mechanism that's used to ascertain a cell's destiny, whether the cell could develop to some nerve, muscular, gender, or somatic cells. Two theories surfaced: when whether a cell's fate is inherent or cell-interactive. Some scientists also refer to these 2 theories as American or European strategy of growth. The European strategy of development identifies the idea that a cell's fate is dependent on their own ancestry whereas the American strategy of growth, a cell's destiny is determined by outdoor environment and standing. The small round worm called C. elegans was used as a foundation for the experiments. This was an outstanding alternative because not only did the worm have a brief life span, reaching sexual maturity in 3 times, but also because the worm is really a hermaphrodite. The fact that the pig has been a hermaphrodite proved to be an amazing advantage. The pig managed to self fertilize; making it feasible for mutants that would otherwise die out without breeding to spread. Also, the worm was transparent which allowed the scientists to look at the progress of each individual cell and also the function that they playwith. Thousands of these very small worms can become a petri dish where they are sometimes seen for recombinations and mutations. An English scientist, John Sulston studied the C. Elegans, using a light microscope equipped with Nomarski contrast optics to trace the worm's cells since the animal produced, tracing the background of each cell. Although thi...
