RETAKE 9A Common ancestry and 9B Changes in Rates

How does the fossil record provide evidence of common ancestry among groups?

• By showing the presence of similar species in different geographical locations

• By displaying transitional forms that link different species

• By indicating the age of the Earth

• By demonstrating the extinction of species

How can molecular homologies be used to support the theory of common ancestry?

• By comparing the physical traits of different species

• By analyzing similarities in DNA sequences among species

• By studying the fossilized remains of ancient organisms

Which of the following scenarios best illustrates abrupt appearance in the fossil record?

• A species gradually changing over millions of years

• A new species appearing suddenly without apparent ancestors

• A species remaining unchanged for a long period

• A species going extinct due to environmental changes

What role does developmental homology play in supporting the theory of common ancestry?

• It shows how different species have similar embryonic stages

• It demonstrates the geographical distribution of species

• It provides evidence of species extinction

• It highlights the differences in adult forms of species

Which of the following is an example of evidence from the fossil record that supports gradualism?

• Fossils showing a sudden change in species

• Fossils indicating a slow transition from one form to another

• Fossils of species that have remained unchanged

• Fossils of species that appear abruptly

How does biogeography provide evidence for evolution?

• By showing that similar species are found in similar environments worldwide

• By demonstrating that species have remained unchanged over time

• By indicating that all species originated from a single location

• By revealing that different species have similar DNA sequences
