The correct Answer is:
**Step-by-Step Text Solution:** 1. **Understanding Horse Evolution**: The evolution of horses is characterized by significant anatomical and morphological changes that have occurred over millions of years. These changes are adaptations to their environment and lifestyle. 2. **Identifying Key Changes**: Among the various changes that have taken place, two of the most important are related to their limbs and teeth. 3. **Change in Limbs**: - Early ancestors of horses had multiple toes, with each foot having several hooves. - Over time, horses evolved to have elongated limbs with a single hoof on each foot, which provides better speed and efficiency for running. - This adaptation is crucial for escaping predators and covering large distances in search of food and water. 4. **Change in Teeth**: - The dental structure of horses also underwent significant changes. - Early horses had teeth adapted for a diet that included softer vegetation, with cutting edge teeth. - As horses evolved, their teeth adapted to a broader diet that included tougher grasses, leading to the development of flatter, more grinding teeth suited for herbivorous feeding. 5. **Conclusion**: Therefore, the two most important anatomical and morphological changes in the evolution of horses are: - **Limbs**: Transition from multiple hooves to a single hoof. - **Teeth**: Change from cutting edge teeth to broad grinding teeth. **Final Answer**: The correct option is **C: Limbs and Teeth**. ---
