Transcript of Introductory Presentation

Obligatory Introductory Lesson
Science!
2 things:
A way to think.
A body of knowledge
Philosophy Religion






Technology Art...
Notes on the "
Scientific Method
"

Reductionism
: Complex Simple
Systems Thinking
Source: David Ng
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 it's parts?
Biosphere
Ecosystem
Community
Population
Organism
Organ
Tissues
Cells
Organelle
Mollecule
Each Level of Organization emerges from the
interactions of the components of the level beneath
2 Major Modes of Scientific Thought
A Generalized System
System
Surroundings
Input
Output
Process
Feedback
Negative Feedback
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
Positive Feedback
To understand systems,
models
are necessary.
The complexity of models is inherently limited.
Reproduction & Development
DNA
Evolution
Regulation
Energy Processing
Development
Reproduction
Life
Higly Ordered
Response
Evolution
Order
Energy & Matter
Cells!
Life's Information System
The Fundamental Unifying Theory of Biology
Charles Darwin!
The world is a very old place.
~4.5 billion years of evolution
Revolutionary by itself
Natural Selection
Common Ancestry
A simple idea:
variations in organisms compete for limited resources
the best competitors survive and reproduce
Repeat
Thats it!
PROFOUND IMPLICATIONS!
All organisms present on the Earth are descended from one common ancestor.

If this doesn't blow your mind, then nothing ever will.
Life's Three
Domains
:
Bacteria
Archea
Eukarya
Protista
Plantae
Fungi
Animalia
Heirarchical Classification
Should reflect common ancestry
The Unity & Diversity of Life
Similarity in cellular organelles in different eukaryotes
Adaptations for flight in gulls
Convergence in flight adaptations in bats
Adaptation
Features that allow an organism to survive in an envronment
Floral adaptations in orchids
Camouflage in Whipporwhils
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 and matter.
Matter cycles through life
Energy flows
Heat
Heat
Light
Chemical
Energy
Different Energy sources for different organisms
However it happens, it has to happen!
The fundamental units of life
Cells are responsible for all properties of life
Cell division in new lung cells:
DNA
is the main information molecule for life
James Watson & Francis Crick
RNA
Protein
Form fits Function!
Big Questions
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 accross several domains of space & time, and why this organization is necessary.
