Tail 32. Which of the following best explains how scientists are able to explain the presence of the femur and pelvis in a whale (refer to the image)? Backbone A. Humans evolved from whales B. The ancestors of whales once had femurs and pelvises C. Whales will be able to walk on land in the future Polvis Femur D. Whales need the femur and pelvis to swim 33. Wings have evolved independently many times on earth. Bats, birds, and moths each use these structures to fly but do not share a recent common ancestor. Which of the following are these structures referred to as? A. Analogous structures B. Homologous structures C. Vestigial structures 34. The forelimbs of humans, horses, cats, and bats are considered to be modifications of anatomically similar structures inherited from a common ancestor. Which of the following are these structures referred to as? A. Analogous structures B. Homologous structures C. Vestigial structures 35. In humans, wisdom teeth and the appendix as well as wings on flightless birds are representations of structures with little to no functional use. Which of the following are these structures referred to as? A. Analogous structures B. Homologous structures C. Vestigial structures

### Educational Content on Comparative Anatomy and Evolution #### Question 32 **Question:** Which of the following best explains how scientists are able to explain the presence of the femur and pelvis in a whale (refer to the image)? - A. Humans evolved from whales - B. The ancestors of whales once had femurs and pelvises - C. Whales will be able to walk on land in the future - D. Whales need the femur and pelvis to swim **Explanation of Diagram:** The diagram shows a whale with labeled anatomical parts including the tail, backbone, pelvis, and femur. It indicates that whales possess remnants of pelvic bones and femurs, which are vestigial structures. #### Question 33 **Question:** Wings have evolved independently many times on Earth. Bats, birds, and moths each use these structures to fly but do not share a recent common ancestor. Which of the following are these structures referred to as? - A. Analogous structures - B. Homologous structures - C. Vestigial structures #### Question 34 **Question:** The forelimbs of humans, horses, cats, and bats are considered to be modifications of anatomically similar structures inherited from a common ancestor. Which of the following are these structures referred to as? - A. Analogous structures - B. Homologous structures - C. Vestigial structures #### Question 35 **Question:** In humans, wisdom teeth and the appendix, as well as wings on flightless birds, are representations of structures with little to no functional use. Which of the following are these structures referred to as? - A. Analogous structures - B. Homologous structures - C. Vestigial structures --- This content is designed to enhance understanding of key evolutionary concepts, including analogous, homologous, and vestigial structures. The explanations and questions provided will help students grasp the significance of structural similarities and differences in various species and how these relate to their evolutionary history.
