Reference no: EM1386447

Question: At the starting of the spring, Dr. Betty Burner notices that there is an equal distribution of long and short-stemmed dandelions in her backyard. By the end of the summer she notices that the majority of the dandelions have short stems. This observation is an example of what biological principle? Develop a hypothesis as to why there was an increase in the proportion of the short-stemmed dandelions within the population.
