Science of Biology is the study of using evidence to learn about the natural world. Scientists use this body of knowledge to gather data, both quantitative (numbers) and qualitative (descriptive), and propose scientific explanations based from scientific experiments. The goal of science is to basically deal with the natural world; collect and organize the necessary information; and eventually propose explanations that can be tested.
Science therefore is an ongoing process and will continue and is a bridge to satisfy our human thirst for knowledge.
