A simplified evolutionary tree (cladogram) shows the relationships among six primate species. Image Description The image shows an evolutionary tree with six primates arranged from left to right: human, chimpanzee, bonobo, gorilla, orangutan, and common gibbon. Each primate is illustrated with a small figure above its name. Below the figures, a branching diagram connects the species. The human branch connects first with a branch shared by chimpanzee and bonobo. This combined branch then connects with the gorilla branch. Further down, these branches join the orangutan branch. All of these branches eventually connect with a deeper branch that leads to the common gibbon. The tree has a step-like structure, with branching points occurring at different depths along a thick, gray vertical line. Based on the evolutionary tree shown above, which two organisms are most closely related?
