Which of the following is NOT a clue about ancestry and relationships used in classifying organisms according to the text?

Common ancestry of seemingly different organisms

Morphology and homology of basic structures

Presence of rudimentary or vestigial organs

Variation of species (correct)

Why are whales classified as mammals, even though they are aquatic creatures like fishes?

Whales have gills like fishes

Whales have fins like fishes

Whales have common ancestry with other mammals (correct)

Whales lay eggs like fishes

What is the primary evidence provided in the text for the theory of evolution through natural selection?

The presence of rudimentary or vestigial organs

The variation of species and their genetic characteristics

The classification of organisms based on their morphology

All of the above (correct)
