An earlier classification system 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.

D. groups organisms based on similarities related to their structure and evolution.

Explanation:

organisms are divided into 7 : domain - kingdom- phylum- class- order- family- genus- species, based on their structure and evolution.
