This fossil snake and this living rat both have a structure in their skull called the quadrate bone. How did this happen?

• The snake and rat are different species, so they are related. They inherited the quadrate bone structure from separate ancestors.

• ll species have their own specific body structures, so it is just a coincidence.

• The snake and rat both share the same ancestor population that had a quadrate bone.

• It is impossible to say. Fossils are very old.

This octopus and this surf clam both have a body structure called a mantle, which covers their soft bodies. However, the octopus’s mantle has muscles that help the octopus swim. The surf clam’s mantle helps the clam build its shell. Why are the mantles different?

• All species have their own specific body structures, so it is just a coincidence

• The octopus and surf clam are different species, so they do not share an ancestor population.

• It is impossible to explain the body structures of different species

• The octopus and surf clam both inherited the mantle structure from a shared ancestor population.

Which of the following best describes the concept of natural selection in the context of evolution?

• The process by which organisms with favorable traits survive and reproduce more successfully.

• The random change in allele frequencies in a population over time.

• The movement of individuals between populations, leading to genetic variation.

• The formation of new species due to geographic isolation.

What is the significance of the fossil record in understanding evolutionary history?

• It provides direct evidence of past life forms and their changes over time.

• It shows the exact age of the Earth.

• It proves that all species have remained unchanged over time.

• It demonstrates that evolution occurs at a constant rate.
