Big Ideas in Biology
What are the central themes of biology?
The study of biology revolves around several
interlocking big ideas:
• evolution;
The cellular basis of life;
information and heredity; • structure and
function;
matter and energy;
• unity and diversity of
growth, development,
life;
and reproduction;
• interdependence in
• homeostasis;
nature;
• and science as a way of knowing.

Big Ideas in Biology
All biological sciences are tied
together by “big ideas” that overlap
and interlock with one another.
Several of these big ideas overlap with
the characteristics of life or the nature of
science.

Interdependence in Nature
All forms of life on Earth are connected into a
biosphere, or “living planet.”
- where ALL living things live
Within the biosphere, organisms are linked to
one another and to the land, water, and air
around them.
Relationships between organisms and their
environments depend on the cycling of matter
and the flow of energy.

Science as a Way of Knowing
The job of science is to use:
- observations, questions and
experiments to explain the natural
world in terms of natural forces
and events.
- Successful scientific research
reveals rules and patterns that
can explain and predict at least
some events in nature.
- Science enables us to take actions
that affect events in the world around
us.
- To make certain that scientific
knowledge is used for the benefit of
society, all of us must understand the
nature of science.

Fields of Biology
How do different fields of biology
differ in their approach to studying
life?
Biology includes many overlapping
fields that use different tools to study
life from the level of molecules to the
entire planet.

Global Ecology
Life on Earth is shaped by weather
patterns and processes in the
atmosphere that we are just beginning
to understand.
Activities of living organisms—
including humans—profoundly
affect both the atmosphere and
climate.

Biotechnology
The field of biotechnology is based on our
ability to “edit” and rewrite the genetic code.
We may soon learn to correct or replace
damaged genes that cause inherited diseases
or genetically engineer bacteria to clean up
toxic wastes.
Biotechnology raises enormous ethical, legal,
and social questions.

Building the Tree of Life
Biologists have discovered and
identified roughly 1.8 million different
kinds of living organisms, and
researchers estimate that somewhere
between 2 and 100 million more forms
of life are waiting to be discovered
around the globe. This paleontologist
studies signs of ancient life—fossilized
dinosaur dung!

Ecology and Evolution of Infectious
Diseases
The relationships between hosts and
pathogens are dynamic and constantly
changing.
Organisms that cause human disease have
their own ecology, which involves our
bodies, medicines we take, and our
interactions with each other and the
environment. Understanding these
interactions is crucial to safeguarding our
future.
