Sample Question
Which of the following best distinguishes derived traits from ancestral traits in taxonomic classification?

Derived traits are shared by all organisms within a kingdom, while ancestral traits are unique to species.

Derived traits are present in a species but absent in their ancestor, while ancestral traits are homologous within groups descended from a common ancestor.

Derived traits are always morphological, while ancestral traits are always genetic.

Derived traits are used only in genetic classification, while ancestral traits are used only in developmental classification.
