The foundation of biology as it exists today is based on five basic principles. They are the cell theory, gene theory, evolution, homeostasis, and laws of thermodynamics.

A universal theme is an idea that applies to anyone regardless of cultural differences, or geographic location. It is a central idea about the human condition. It is a generalization about life or human nature; they deal with basic human concerns.

Some of the more common universal themes found in literature include individual struggle towards a personal goal, a person’s struggle with humanity, falling in love, life cycles, karma, coping with tragedy, adolescence and discovering the world around us.

Summary. Four basic principles or theories unify all fields of biology. Those principles are cell theory, gene theory, homeostasis, and evolutionary theory. According to cell theory, all living things are made of cells and come from other living cells.

Four unifying principles form the foundation of modern biology: cell theory, evolution, genetics and homeostasis. Biology as a separate science was developed in the nineteenth century, as scientists discovered that organisms shared fundamental characteristics.

Human biology is an interdisciplinary area of academic study that examines humans through the influences and interplay of many diverse fields such as genetics, evolution, physiology, anatomy, epidemiology, anthropology, ecology, nutrition, population genetics, and sociocultural influences.

Reproduction, homeostasis, evolution, metabolism, heredity.

From the 1700s onward, the development of cell and evolutionary theories have played central roles in unifying how biologists go about studying these issues.
