The arm of a human, the flipper of a whale, and the wing of a bat all have similar bone structures. Therefore, these parts of the body would all be considered...

• homologous structures

• vestigial structures

• transitional fossils

• common ancestors

The two most important things that the fossil record tells us about the history of life on Earth are...

• some species go extinct, and it is impossible for new species to take their place

• some species go extinct, and new species appear over time

• species usually never go extinct, but somehow dinosaurs did go extinct

• Earth never changes, and changes to life on Earth happen very quickly

A bird's wing and a butterfly's wing have the same function, but they have very different structures. These structures are classified as follows:

• homologous structures

• analogous structures

• vestigial structures

• embryological homologues

Evolutionary biologists say that similarities between different species are evidence of which of the following?

• Organs shrinking and losing their function

• Formation of the first cell in an organic soup
