What is the role of observation and experiment in biological cognition?

Research methods are a source of knowledge and discovery. There are many varieties of them, but if we talk about the role of observation and experiment, then we will say that these are the first methods that were used by people and thanks to them the very first discoveries were made. They are clearly interconnected: observation allows you to analyze, notice patterns, features and describe them. After receiving the factual material, a hypothesis appears that needs to be tested. This will be helped by an experimental method with which you can simulate the conditions necessary for refutation or proof.
