Which of the Following Categories of Organisms is Least Likely

Question

Which of the following categories of organisms is least likely to be revised?
A)kingdom
B)class
C)order
D)phylum
E)species

Accepted Answer

Species are the most specific level of classification and are based on the genetic, anatomical, and behavioral characteristics of an organism. Therefore, once a species is correctly identified and described, it is unlikely to be revised. In contrast, higher levels of classification like kingdom, phylum, class, and order are based on broader characteristics that may change as new information and research become available.
