Front

If an organism has a vestigial structure, what does that imply about its evolutionary history?

Back

The structure likely once had a function in an early ancestor.

Front

What is the significance of vestigial structures in evolutionary biology?

Back

They provide evidence of common ancestry and evolutionary change.

Front

What is the term for the study of fossils and their role in understanding evolution?

Back

Paleontology.

Front

What is the main idea of natural selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What evidence supports the theory of evolution through comparative anatomy?

Back

Similar structures in different species indicate a common ancestor.

Front

What is the role of molecular biology in understanding evolution?

Back

It examines genetic similarities and differences to trace evolutionary relationships.
