Classification and Taxonomy

1.   Direct Evidence (Fossils)

2.   Indirect Evidence (4 types)

3.   Isolation Mechanism and Evolution

Number One

Question: What organism are these bones from?

Using a skeleton of a limb, how can we observe some evidence of an animals structure and function?

What structures are in the limb?

Refer to class notes posted at web blog.

There are three constants in life..paradox, change and humour.

Find a bone called a Humerus, you will see evidence of change and proof of why bones can be called funny bones..
