| | To date, we have discussed nature of fossils and geologic principles. |
| | In the next several lectures, we will cover the diversity of life and the major biologic principles needed to interpret the fossil record. |
| | Life is "organized/catagorized" by humans |
| | This organization evolves with our understanding |
| | Life is not organized by increasing steps of evolution |
