Life Sciences

Life sciences is the scientific study of living organisms, from the molecular level to their interactions with each other and their environment. The production of knowledge in science is an ongoing endeavor. Scientific knowledge changes over time as scientists’ knowledge and understanding improve and as people’s world views change. Scientists are constantly involved in debates and disagreements, but eventually reach a consensus on how the world works. Scientific theories taught in schools are validated and generally accepted.

About the Book

The purpose of this chapter is to outline the skills needed to become a life scientist. Living systems have levels of organization ranging from molecular to biomass. Furthermore, all life on Earth is dynamic, with various processes in equilibrium at all levels of organization. The life forms we observe today are the result of billions of years of change.

In this chapter, you will learn how to use the scientific method to gather evidence to build theories that explain what we observe. The scientific method requires us to constantly reexamine our understanding by testing new evidence with current theories and changing the theory if the evidence does not meet the test. The scientific method is therefore a powerful tool used throughout the physical and life sciences.
