Quizplus · Accepted Answer

If the two groups of lizards remain isolated for a long period of time, they will no longer have gene flow between them. Over time, genetic differences will accumulate between the two groups, leading to divergence and potentially speciation. This process is known as allopatric speciation. Thus, the best choice is E.
