Anoles are a family of lizards found throughout the americas. green anoles, anolis carolinensis, are native to a specific area of florida. in this
area, the primary territory of green anoles was once along the ground and in low-level branches. however, the introduction of brown anoles,
anolis sagre, from cuba forced green anoles to shift their territory to the tops of trees. the branches at the treetops are smoother and
thinner than those close to the ground. over time, the toe pads of the green anoles have become larger and stickier.
what is the best explanation for the change in green anoles' toe pads?
