How to show animal lineage/pedigree in WordPress?

From Wikipedia

Animalia is the taxonomic kingdom comprising all animals (including human beings).

From the Codex

Taxonomy is one of those words that most people never hear or use. Basically, a taxonomy is a way to group things together.

For example, I might have a bunch of different types of animals. I can group them together according to various characteristics and then assign those groups names. This is something most people encounter in biology classes, and it is known as the Linnaean Taxonomy.

In WordPress, a “taxonomy” is a grouping mechanism for some posts (or links or custom post types).

Just use Categories -a type of taxonomy- to group and categorize them.
