When thinking of a theory, the first step is a question, which is somehow always a ‘Why?’ or a ‘How?’. We wonder and look for patterns between evidently unrelated things. Darwin’s question was “How did evolution happen?”.
The next step is to develop a theory to explain a law. Darwin was not a true believer in evolution but he was exposed to the scientific beliefs behind the theory quite often in his studies while at Cambridge. Darwin’s Theory of Evolution does not explain a law because it cannot be expressed in a concise mathematical equation.
A law explains what will happen under certain circumstances, while a theory explains how it happens, and that is exactly what Darwin’s theory does.
The third step to conceiving a theory is researching the academic guides to the theory. The first Theory of Evolution was suggested by a French scientist Jean Lamarck. He correctly deduced from fossil evidence that species changed over time, but he had no evidence to explain how evolution functioned.

Darwin’s hypothesis was that “Species originated by means of natural selection, or through the preservation of the favoured races in the struggle for life.”.
To test a hypothesis, it is a must to design an experiment, then find support to access certain equipment and resources, keep precise records of findings and conclusions, evaluate the results by comparing the predictions against each other and against the outcomes of the experiments, and then establish certainty by seeing if the results support the hypothesis.
From 1831-1836, Darwin journeyed on the HMS Beagle, a ship whose mission was to travel around the world in pursuit of new scientific findings.
Darwin worked as the naturalist on board the ship, gathering thousands of specimens from numerous countries around the
