Observance of Artificial Selection: Technical Study of Wisconsin Fast Plants 5th and 6th period AP Biology Due: 12/16/13 Abstract This experiment was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism ’s traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in
