Scientific method and hypothesis-driven science

Biology is a hypothesis-driven science. Biologists make observations that lead to new biological questions. They then formulate and test hypotheses in order to explain their observations and thereby answer the resulting question. The results of the testing determine whether their thinking was correc...
