WebThe Progressive Hypothesis, also known as the Escape Hypothesis, says that the viruses originated from the genetic elements that were able to move between the cells; The Regressive Hypothesis , also known as the Reduction Hypothesis, states viruses are the remains of the cellular organisms; WebThe Progressive Hypotheses As per this hypothesis, viruses originated from simple genetic material. We have discussed earlier that these microbes have a simple yet effective protein covering over a small amount of genetic material. There are no cell organelles present in viruses. Hence, we cannot consider viruses as cells.
