The correct Answer is:
To determine which of the following is a connecting link between reptiles and mammals, we need to analyze the options provided: 1. **Echidna** 2. **Secondary Dinosaur** 3. **Seymouria** 4. **Lattimeria** ### Step-by-Step Solution: 1. **Understanding the Concept of Connecting Links**: - A connecting link is an organism that exhibits characteristics of two different groups, in this case, reptiles and mammals. It helps in understanding the evolutionary transition between these two classes. 2. **Analyzing Each Option**: - **Echidna**: This is a monotreme, a type of egg-laying mammal. It has features that are characteristic of both reptiles (like laying eggs) and mammals (like having fur and producing milk). This makes it a strong candidate for a connecting link. - **Secondary Dinosaur**: This term does not refer to a specific organism and is not recognized as a connecting link between reptiles and mammals. - **Seymouria**: This is an extinct genus that shows features of both amphibians and reptiles. While it is an important transitional fossil, it is not specifically a link between reptiles and mammals. - **Lattimeria**: This is a genus of coelacanth fish and does not serve as a connecting link between reptiles and mammals. 3. **Conclusion**: - Based on the analysis, **Echidna** is the correct answer as it serves as a connecting link between reptiles and mammals due to its unique characteristics. ### Final Answer: **Echidna** is the connecting link between reptiles and mammals. ---
