During embryological development, the mouse limb and pig limb start out similar in structure and composition. As development continues, the pig limb changes to lose digits compared to the mouse limb. These changes in the pig's limb help it adapt to a life of running and foraging on land, providing better stability and support. The mouse’s limb develops differently because it does not need to support the same weight or navigate the same terrain as the pig, allowing for more dextrous and agile movement.
Use your observations in the previous questions and Figure 3 to correctly complete the sentence. These sentences explain how the pig’s limb develops differently from the mouse’s limb and how these changes helped pigs adapt over time.
