Question

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 stickier. What is the best explanation for the change in green anoles' toe pads?

Answer 1

The best explanation for the change in green anoles' toe pads is; speciation.

It begins with genetic changes in the population. Natural selection begins to favor individuals who develop the traits that are advantageous to their environment.  The formers traits are steadily weaned off the population by natural selection pressures. Over time, the allelic frequency of the population shifts from that former population in which they originated and a new species develops.

Answer:

The answer is B

Explanation:

This is the most accurate answer because it uses “some individuals”. Mutations are random and sometimes they help survive in conditions and so they are passed on to the next generation.
