Darwin’s theory of natural selection states that evolutionary change occurs when individuals produce variations in each generation and differential ways of survival by combining these variable characters. Individuals with variable characteristics, which increase their chances of survival, will have more opportunities to reproduce and their offspring will benefit from these advantageous characteristics. Similar to this theory, the western corn rootworm has evolved to produce enzymes in their gut that has enabled them to become resistant to corn-soybean-corn rotation. The enzymes inhibitors enables them to survive for two to three days in the soybeans fields which is enough for some of rootworms to lay eggs, when corns are planted in the same fields the rootworm larvae feeds on the corn roots.
The modern view of evolution as a change in allele frequencies defines evolution as not only the development of new species from older ones but also the small changes within species from generation to generation-over long periods. Similarly, the western corn rootworm has been able to produce special class proteinases over long period of time, these small changes have enabled them to survive on soybean ...Download file to see next pagesRead More
