Read each question carefully and answer to the best of your ability. This worksheet will help you understand analogous structures.
Analogous structures are body parts in different species that perform similar functions but have different evolutionary origins. This means they evolved independently to adapt to similar environments or challenges.
1. Which of the following best describes analogous structures?
Structures with similar origins but different functions.
Structures with similar functions but different origins.
Structures that are identical in all species.
Structures found only in extinct animals.
2. The wings of a bird and the wings of an insect are considered analogous structures because:
They have the same bone structure.
They both help the animals fly but evolved differently.
They share a common ancestor with wings.
They are made of the exact same materials.
3. Analogous structures perform similar but have different evolutionary .
4. The streamlined body shapes of a shark and a dolphin are examples of structures, as they both help in swimming efficiently.
5. Explain in your own words what is meant by 'different evolutionary origins' when discussing analogous structures.
Match the animal with its analogous structure example.
6. Bird
a. Insect wing
7. Dolphin
b. Shark fin
8. Observe the images below of a bird wing and an insect wing. Both are used for flight. Describe one key difference in their structure that suggests they evolved independently (are analogous).
