History of biology Our fascination with biology has a long history. Even early humans History of biology Our fascination with biology has a long history. Even early humans had to study the animals that they hunted and know where to find the plants that they gathered for food.

Framework of understanding All the branches of biology can be unified within a framework Framework of understanding All the branches of biology can be unified within a framework of five basic understandings about living things. Studying the details of these five ideas provides the endless fascination of biological research:

Cell Theory: There are three parts to cell theory — the cell is the Cell Theory: There are three parts to cell theory — the cell is the basic unit of life, all living things are composed of cells, and all cells arise from pre-existing cells.

Energy: All living things require energy, and energy flows between organisms and the environment. Energy: All living things require energy, and energy flows between organisms and the environment.

Heredity: All living things have DNA and genetic information codes the structure and function Heredity: All living things have DNA and genetic information codes the structure and function of all cells.

Equilibrium: All living things must maintain homeostasis, a state of balanced equilibrium between the Equilibrium: All living things must maintain homeostasis, a state of balanced equilibrium between the organism and its environment.

Evolution: This is the overall unifying concept of biology. Evolution is the change over Evolution: This is the overall unifying concept of biology. Evolution is the change over time that is the engine of biological diversity.

We may discover ways to save our oceans while using them to produce enough We may discover ways to save our oceans while using them to produce enough food to feed the nations. We may “grow” batteries from bacteria or light buildings with bioluminescent fungi. The possibilities are endless; biology is just coming into its own.
