Question 8 The presence of tiny hairs, called setae, on the toe pads of some geckos is associated with the ability to adhere to smooth surfaces. This ability allows geckos to climb in areas where many predators cannot. Scientists studying the evolution of setae have identified three closely related species of gecko, only one of which can adhere to smooth surfaces. A model of the evolutionary relatedness between these species is represented in the figure. •G. humeralis Can adhere O Cannot adhere 2 O G. concinnatus Submi O G. antillensis Which of the following statements is an accurate interpretation of the labeled branch points on the model? A Location 1 represents the common ancestor of only two of the three species. Locations 1 and 2 represent extinction events for G. humeralis. Location 3 represents the common ancestor both G. humeralis and G. concinnatus. D Locations 2 and 3 represent speciation events.
