Question

In this experiment, researchers placed a pair of lizards from Iron Cay, which has large trees, in an experimental island, which has only small bushes and grass. After several generations, they measured the leg length of 10 lizards from each site. Which group of lizards had longer legs on average?

Answer 1

The lizards from Iron Cay.

Step-by-step 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.
