charles darwin is credited with outlining the principles of evolution by natural selection. what aspects of the scientific method can be identified in darwin's work

Charles Darwin's work followed the rules of hypotheses creation and testing.

In order to prove a scientific suspicion, a true scientist has to follow the above methods.

So Darwin probably theorized that the offspring of certain living entities were by either environmental conditioning or by natural selection different genetically from their parent.

He tried this hypothesis over time and using the results he got, modified his theory.
