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 sagrei 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 stickler What is the best explanation for the change in green anoles toe pads OA The change in conditions caused mutations in green anoles that gave them beneficial traits for survival and reproduction and those mutations were passed on to the next generation O B The feet of the green anoles became larger and stickler as they used them which helped the green anoles to better survive reproduce and pass the trait on to the next generation OC Gene flow between the green and brown anoles provided the green anoles with traits that helped them survive and reproduce and those traits were passed on to the next generation OD Some individuals in the green anole population had mutations that helped them survive and reproduce in the new conditions so their genes were passed on to the next generation
