What are the 7 levels of classification in current system classification?

The current system of classification, called taxonomy, uses a hierarchical system with eight levels, not seven. Here they are from broadest to most specific:

1. Domain: The broadest level, encompassing all of life. There are three domains: Bacteria, Archaea, and Eukarya.

2. Kingdom: A major grouping within a domain. Examples include Animalia (animals), Plantae (plants), and Fungi.

3. Phylum (or Division in plants): A group of closely related classes. Examples include Chordata (animals with a backbone) and Magnoliophyta (flowering plants).

4. Class: A group of closely related orders. Examples include Mammalia (mammals) and Aves (birds).

5. Order: A group of closely related families. Examples include Primates (monkeys, apes, humans) and Carnivora (meat-eating mammals).

6. Family: A group of closely related genera. Examples include Felidae (cats) and Canidae (dogs).

7. Genus: A group of closely related species. Examples include *Panthera* (lions, tigers, leopards) and *Canis* (dogs, wolves, coyotes).

8. Species: The most specific level, representing a group of organisms that can interbreed and produce fertile offspring. Examples include *Panthera leo* (lion) and *Canis lupus* (wolf).

So, while there are 7 levels listed in many resources, it's important to remember there is an eighth level, domain, which sits above kingdom.
