Evidence of Evolution Worksheet

Evidence of Evolution

Read each question carefully and answer to the best of your ability. This worksheet will test your understanding of the different types of evidence that support the theory of evolution.

1. Which type of evidence involves comparing the skeletal structures of different organisms to find similarities?

2. The presence of gill slits and tails in early human embryos suggests a common ancestry with which group of animals?

3. The preserved remains or traces of organisms from the past are called  .

4. Structures that have a similar evolutionary origin but different functions, like the wing of a bat and the arm of a human, are known as   structures.

5. Vestigial structures, such as the human appendix, have no known function and provide evidence of evolution.

6. DNA and protein similarities among different species provide strong biochemical evidence for evolution.

7. Observe the image below showing homologous structures.

Explain how homologous structures provide evidence for common ancestry among different species. Give an example from the image.

8. Describe how the fossil record supports the theory of evolution. What can we learn from fossils about past life forms?

Use the words below to complete the sentences.

9. The study of the development of embryos provides evidence of shared developmental patterns, which is known as  .

10. The more similar the   sequences are between two species, the more closely related they are considered to be.
