Why would scientists want to use a taxonomic system that is standardized?
In order to avoid confusion with the identification of organisms.
Because Linnaeus established a system.
So that Latin names can be applied for a practical purpose.
In order to place organisms in different groups.

Kingdom
Class
Order
Genus
