Back

Front

What are transitional fossils?

Back

How do scientists use fossils to determine evolutionary relationships?

Back

By comparing similarities and differences in fossil structures to identify common ancestry.

Front

Why is the age of fossils important?

Back

Knowing the age helps scientists understand the sequence of evolutionary events.

Front

How do fossils demonstrate that living things evolved from earlier species?

Back

Fossils show gradual changes in traits over time, linking modern species to ancient ancestors.
