Learning outcomes Understand why it is important to have a good working knowledge of biology. Understand the processes involved in scientific discovery. Describe how a hypothesis is formulated and how it becomes a theory. Define variable and understand its involvement in a controlled experiment. Cite the evidence from Darwin’s voyage that initiated his ideas on evolution. Explain the revolutionary aspects of Darwin’s evolutionary concepts. Know the scientists who greatly influenced Darwin and how their work

contributed to his. Understand why natural selection is the driving force of evolution.

List the evidence after Darwin’s time that further supports the validity of the theory of evolution.

List the themes that unify biology as a science.
