Lederbergs' experiment of the prevalence of mutations before selective culture was proved by replica plating. They spread bacteria on the plate and allowed them to grow. Next, they stamped the growth on the new plate which was already containing penicillin. The bacteria were able to grow on this plate, even when they never exposed to the antibiotic before. This proved that some of the bacteria were already mutated and were not as a result of exposure to selective culture conditions.

</span><span>Thus, to achieve the creative approach above the researchers must utilize and apply the </span>scientific method in gathering, interpreting and analyzing empirical evidence<span>. </span>

<span>Empirical evidence, data or knowledge is an obtained set of facts or figures or existing and presenting data that was yielded during the process of experimentation or scientific discovery. These empirical data or evidence is further studied and investigated by the scientist in a formal scientific approach which follows the steps of observation, making a hypothesis, gathering data, interpreting data and evaluating the data. These steps of the scientific approach are vital in the course to explain and discuss the result and evidence obtained during the process. </span>
