o  What makes a “good” argument?

o  Comparing Darwin to Lamarck

o  Comparing Natural to Artificial Selection

Number One

Example: “This is a good song”

https://www.youtube.com/watch?v=KEI4qSrkPAs

Question One: What makes a good song?

·      Snappy lyrics that make no sense!

·      Repeating musical pattern!

·      Hidden innuendo in song!

Question Two: What if we compare same song but two different versions?

Performace..

Feedback…too intense..another artist please..revision

Question Three:

Why should anyone get a dog?

Make a Pro and Con Table

Pro                               Con

Companionship         Responsibility

Exercise                       Expensive

Release Stress             Allergies

Use following data to generate a if and then statement

Example

A then B

If our family wants to live happy, then we

should reduce stress.

B then C

A way to reduce stress is to interact a dog.

A then C

If our family wants to live happy, then we should get a dog!

Number Two

So whose theory did Darwin argue with?

Darwin verse Lamarack

Darwin’s argument

A yahoo version

An more academic version

http://www.plosin.com/work/OneLongArgument.html

Lets revise..and simply

If a population grows without any limiting factor is grows at a geometric rate.

Geometric growth leads to over population

Yet there is no over population and this is due to “a struggle for existence” ( related to economics idea by Malthus)

Part two

With a population, the is a diverse range of how a trait is shown. (think about a litter of puppies).

Those traits that allow the species to survive, are passed onto the next generation.

The mechanism that select which traits are passied onto the next generation is a natural selection.

Note..”survival of the fittest” was not first written by Darwin.

https://en.wikipedia.org/wiki/Survival_of_the_fittest

Also

Wallace also noticed a selection process by natural sources in his collection of animals.

http://people.wku.edu/charles.smith/index1.htm

The main focus of Darwin’s argument was to challenge Lamarck’s idea that individual species changed with time due to use and disuse of traits.

He used fossil records and data acquired in his five year voyage to propose “the origin of the species”.

In regards to his interpretation of changes in beak structure of finches, we should not that

Each island had limited predation, a unique habitat that created a variety of food sources. These factors within the environment were used to support his argument.

Focus Questions:

Is a theory a fact?

How does the scientific method provide structure to create a theory?

How are direct and indirect evidence used to replace an actual experiment that validates Darwin’s ideas?

Is there a way to create an experiment that could validate the mechanisms of evolution?

For Darwin, what selects a trait?

How does this differ with Lamarck?

What is a common missing factor that both Darwin and Lamarck did not know about?

How could you disprove Lamarck idea of an acquired characteristics?

Note:

This is not a proof that changes occur with time, it is a proposal of the mechanism as to why things change with time.

Artificial Selection Rap

Theories can change with time and they are not facts.

To create a logically sound argument, it is wise to examine objective evidence that both supports and argues the premise that you are defending.

Do not go into a battle of wits with an unarmed opponent.
