        Evolution and Adaptation of Plant and Pest Populations

        Since soybean plants and nematodes are both living things, they are constantly evolving and adapting to their environment. Genetic variety results in physical differences in organisms. When humans transitioned from hunting and gathering to agriculture they had to select the type of grains they would grow from the wild grains around them and select the characteristics they deemed desirable. The domestication of soybean plants was an act of artificial selection. But while the genetic information in soybean plants have been naturally and artificially selected over the years, the soybean cyst nematode has also continued to evolve and adapt.
