An earlier classification grouped organisms by whether they inhabited the air, land or sea. However, the five-kingdoms-of-life and three-domains system divided into class-order-family-genus-species as described in this chapter is superior because it
A) better represents the origin of features held in common-the unity of life in DNA, etc.
B) better reflects the origin of adaptations-the diversity of life for differing environments.
C) allows the organization of over 900,000 different species.
D) groups organisms based on similarities related to their structure and evolution.
E) All of the choices are correct.

The five-kingdoms-of-life and three-domains system is superior because it incorporates all the criteria mentioned in the options. It better represents the origin of features held in common, such as DNA, and reflects the origin of adaptations due to the diversity of life for differing environments. Additionally, it is able to organize over 900,000 different species based on similarities related to their structure and evolution. Therefore, all the choices are correct.
