Table 23-1 Based on the accompanying table, one characteristic used at the class level of classification for corn is:

Due to our increasing ability to analyze DNA sequences and other molecular data of organisms, scientists are more often classifying organisms by their:

An example of homoplastic structures is the wing of a butterfly and:

The traditional class Reptilia is ____ because it does not include all descendants of the most recent common ancestor of reptiles.

Scientists may compare similarities between nucleotide sequences of organisms to determine their evolutionary history. This is known as:
