Discrepancy Of Darwin's Experiments By Francisco Ayala
Due to the fact that there was a discrepancy of how Darwin approached the scientific method in his experiments and published literatures, Francisco Ayala discussed the importance of a hypothesis. Inductionist cannons, such as Francis Bacon and John Stuart Mill, used observations without any predispositions to create a general statement, which influenced Darwin to perceive that his observations were used to contribute to his theory of natural selection rather than to have his theory affect the way he accumulated his observations.
It is commonplace to view that science is inductive, yet induction has its disadvantages.

find a collection of data that suits a phenomena. On the other hand, a universal truth may not be specific enough to explain every observation made on a certain topic. For example, even if all observed swans are white, it cannot be concluded that all swans are white because there is a chance the next swan observed will not be white. This leads to the fact that a hypothesis cannot be formulated from observational events.
With induction, scientists were able to gather information easily and sort them into a broad conclusion; however, it is an essential part of the scientific method for the hypothesis to be tested through experiences from the natural world. Contributed by two philosophers of the 20th century, this method, the hypothetico-deductive method can essentially justify the hypothesis with credible observations and experiences or reject the hypothesis if it predicts the wrong results. A preconceived idea must be present in order to test for expected results.
Not only do observations from the natural world affect the validity of the hypothesis, the creation of various experiments can also contribute to the justification of the hypothesis.

In molecular biology, various situations of experiments were tested to find out what was responsible for transformation. Without imagination, certain discoveries would not have occurred and scientists would not be able to create experiments specifically for those hypotheses. Imaginative hypotheses are required before proceeding with the scientific method because they provide scientists with goals to achieve as they prove their hypotheses.
The hypothesis is the main part of scientific inquiry; it must meet four criteria in order to test it.
The hypothesis must not be self-contradictory while it includes a phenomena that explains the reason for the hypothesis. It must be tested for its consistency with hypotheses of a certain topic that are already recognized in the field of science. The fourth criteria, the criterion of demarcation, requires the possibility that preconceived ideas and observations will lead to a falsifiable hypothesis; a scientific hypothesis must be consistent with some unobserved cases in the natural world that may be subject to falsification. A universal truth can be proven wrong with just a single statement, but it can never be proven correct with several statements.
Ayala links the scientific method with Darwin’s process of explaining his theory of natural selection. Although Darwin had thought he was using induction, he had been using the hypothetico-deductive method, allowing him to use evidence of the adaptation of organisms to support evolution which supported his theory of natural selection. Importantly, Darwin accepted that a falsified hypothesis is possible and can set back scientists from their progress, but at the same time, open doors about the truth of their hypothesis.
Ayala depicted that a hypothesis is a very crucial component of scientific inquiry.
