Describe the structure of the modern classification system?

The modern classification system uses homologies to group species into larger and more general categories. A speciesis a group of organisms that is capable of breeding with each other. Species with many of the similar characteristics are grouped in the same genus (plural: genera). Similar genera are grouped in the same family. A group of related families is called an order. A group of related orders is called a class. A phylum (plural: phyla) is a group of related classes. A kingdom is a group made up of similar phyla.

The order from most specific to most general is:

1. Species
2. Genus
3. Family
4. Order
5. Class
6. Phylum
7. Kingdom
