Why was it necessary to do serial transfers in the experiment illustrated above?
A)Each serial transfer is equivalent to a generation and thus provided an opportunity for natural selection to occur over time.
B)Each serial transfer was necessary to reintroduce RNA into the system.
C)Each serial transfer decreased the population size so that genetic drift could occur.
D)Because the experiment took place in a lab, serial transfers were necessary so that the researchers could go home at night.
