To solve this problem, we need to identify which set of examples does not represent divergent evolution. Let's analyze each option:$\newline \bullet$Option 1: Brain of bat, man, and cheetah$\newline$ - The brain of these mammals shows divergent evolution as they have evolved differently to adapt to their specific needs, despite having a common ancestor.$\newline \bullet$Option 2: Heart of bat, man, and cheetah$\newline$ - The heart in these mammals is an example of divergent evolution, as it has adapted to different lifestyles and environments while originating from a common ancestor.$\newline \bullet$Option 3: Forelimbs of man, bat, and cheetah$\newline$ - The forelimbs of these mammals are classic examples of divergent evolution, having evolved into different forms and functions (e.g., grasping, flying, running) from a common ancestral limb.$\newline \bullet$Option 4: Eye of octopus, bat, and man$\newline$ - The eye of an octopus and the eyes of mammals like bats and humans are examples of convergent evolution, not divergent evolution. They have evolved independently to perform similar functions, despite not sharing a recent common ancestor.$\newline$Therefore, the incorrect option is Option 4, as it represents convergent evolution rather than divergent evolution.
