Read each question carefully and answer to the best of your ability. This worksheet will test your understanding of analogous structures.
1. Which of the following best describes analogous structures?
Structures with a common evolutionary origin but different functions.
Structures with different evolutionary origins but similar functions.
Structures that have lost their original function over time.
Structures that are identical in all species.
2. The wings of a bat and the wings of an insect are considered analogous structures because:
They have the same underlying bone structure.
They evolved from a common ancestor with wings.
They both serve the function of flight, but evolved independently.
They are both made of the same type of tissue.
3. Analogous structures are a result of evolution, where different species evolve similar traits due to similar environmental pressures.
4. The streamlined body shapes of a dolphin and a shark are an example of structures.
5. Analogous structures provide strong evidence for common ancestry between organisms.
True
False
6. The eyes of a human and the eyes of an octopus are analogous structures.
True
False
7. Explain the difference between analogous and homologous structures. Provide an example for each.
