Have any big ideas?
An example of a big theme you see in
books and movies is the struggle between
good and evil (think Batman vs. the Joker)
What might you think would be some of
the themes you would find as we humans
study life?
Here are some we will focus on…

Themes in the Study of
Life
1.) Structure is related to function. • What, exactly, does that mean?
• In order to understand the function of something, then,
you must understand its structure.
• Have you ever played horseshoes? How does the
structure of these horseshoes relate to their function?

2. Energy Transfer
Why do you need energy?
Where does it come from?
What do you do with it?
To understand life it is necessary to study these energy transfers.

3. Unity and Diversity
There are great differences among
organisms. • Over 600,000 beetle species, for example
There are great similarities also. • Especially chemical ones, especially DNA
Studying this unity and diversity gives
evidence to relatedness and past
evolutionary history.

4. Systems and
Interactions
What kind of systems do you find inside of you?
What kind of systems are you a part of?
What is homeostasis?
No organism can be fully understood alone; they are all part of a system.

Levels of organization
Let’s break down a
zebra…
What are “emergent
properties”?

5. Science, Technology
and Society
What is an example of how science
affects society? Vice versa?
Science creates technology and
technology drives the advance of science
and society.

Science and society
Science has
taught us that
we must
recycle things
like paper,
glass and
plastic Wal-
Mart bags

6. Evolution by Natural
Selection
Define “evolution”.
Define “natural selection”.
Why would this be called the “unifying
theme” of biology?

AP THEMES
The AP program mixes, matches and
combines the themes from different
textbooks into these four, which they now
call “Big Ideas”
1. The diversity and unity of life can be
explained by the process of evolution.
A. This is the main theme in the study of life.
B. The process of evolution is driven by the
process of Natural Selection.

AP Theme #2
2. Living systems have multiple
mechanisms to store, retrieve and
transmit information.
A. This deals mainly with DNA in cells
and all the ways information is
perceived and transmitted in
organisms. For example – see a baseball,
hit a baseball, tell someone about it.

AP Theme #3
3. Interdependent relationships
characterize biological systems, and these
interactions give rise to emergent
properties.
A. All sorts of systems, involving everything
from very small particles to very large
continents are operating in the
universe.

AP Theme #4
4. Biological systems utilize energy and
molecular building blocks to grow,
reproduce and maintain homeostasis.
A. This involves things like how plants use
sunlight and how we use food like a car uses
gas as well as how we keep things like body
temperature and blood sugar from getting too
high or low.
