How do scientists use the fossil record to support the theory of evolution?

Question

1. The fossil record shows changes in species over time
2. The fossil record shows that the first living creatures were more complex than today
3. The fossil record shows that horses have not changed throughout history
4. The fossil record is not used by scientists to support evolution

Answer 1

5. The fossil record provides evidence of transitional forms, linking different species together and showing how they have evolved over millions of years
6. By examining the distribution of fossilized organisms in different layers of rock, scientists can see how life has changed and diversified over geologic time
7. Fossils of extinct species can demonstrate how life forms that are no longer present have evolved into modern-day organisms
8. Comparing the anatomical features of fossils to modern species can show how organisms have adapted and evolved to fit their environments
9. Fossil evidence can help fill in gaps in the evolutionary history of species and provide insight into the processes that have shaped life on Earth.
