Answer:
The lizards from Iron Cay.
Explanation:
After several generations, they measured the leg length of 10 lizards from each site. The lizards from Iron Cay had longer legs on average. These lizards are trunk-ground anoles, which have long legs adapted to both perch large trees and walk on the ground. But due to evolution, the lizards in the experimental island had shorter legs because longer legs were no needed there.
