Let Us Begin...
Science is not the only way of thinking
How is science similar? How is it different?
Is a thing just the sum of its parts?
Each Level of Organization
interactions of the components of the level beneath
2 Major Modes of Scientific Thought
A Generalized System
The output decreases the process.
"more gets you less"
Regulatory in nature
The output increases the process.
"more gets you more"
Accelerating in nature
Leads to a Transformation
To understand systems,
The complexity of models is inherently limited.
Make Sure You Can
How is science different from other ways of understanding the Universe?
What are the major questions that biologists study?
Explain how science works as a process.
Contrast science with other ways of looking at the Universe.
Compare the approach taken by reductionist & systems-level modes of scientific analysis.
Explain why biology is a science.
Give a brief explanation of how life is organized across several domains of space & time, and why this organization is necessary.
The Seven "
1. Use of representations and models 4. Collect Appropriate
2. Use of appropriate mathematics 5. Analyze Data
3. Engage in Scientific Questioning 6. Use Scientific
7. Work with information across multiple domains
Interactions within and between ecosystems
Life is the most ordered system in the Universe
Life is subject to the energy constraints of the Universe.
No magic allowed!
The high order in living systems is maintained by processing energy.
Matter cycles through life
Different Energy sources for different organisms
The fundamental units of life
Cells are responsible for all properties of life
Cell division in new lung cells:
is the main information molecule for life
James Watson & Francis Crick
A Focus on Unifying Themes
How are living systems monitored and coordinated?
How do living systems develop?
How are living systems maintained?
How do living systems receive and exchange information?
Interactions within and between individuals
Interactions within and between populations
The Fundamental Unifying Theory of Biology
The world is a very old place.
~4.5 billion years of evolution
Features that allow an organism to survive in an environment
Floral adaptations in orchids
Camouflage in Whipporwhils
