A founding population of lizards arrives on an island: Which type of isolation would most likely result in this population becoming a new species? temporal geographical anatomical behavioral

The question is asking about the type of isolation that would most likely lead to a founding population of lizards becoming a new species when they arrive on an island. The options provided are temporal, geographical, anatomical, and behavioral isolation. <br /><br />1. Temporal isolation occurs when two species breed at different times, which prevents them from interbreeding. This is not applicable in this scenario as the lizards are on the same island and there is no mention of different breeding times.<br /><br />2. Geographical isolation happens when a population is separated by a physical barrier, such as an ocean or a mountain range, which prevents them from interbreeding with other populations. In this case, the lizards are on an island, which is a physical barrier separating them from other populations. This is the most likely type of isolation that would lead to the lizards becoming a new species.<br /><br />3. Anatomical isolation occurs when two species have different physical structures that prevent them from interbreeding. This is not applicable in this scenario as there is no mention of different physical structures.<br /><br />4. Behavioral isolation happens when two species have different mating behaviors that prevent them from interbreeding. This is not applicable in this scenario as there is no mention of different mating behaviors.<br /><br />Therefore, the most likely type of isolation that would result in the lizards becoming a new species is geographical isolation.
