The order of original appearance on earth, from the earliest to the most recent organism is D. bacteria, trilobites, lizards, rhinoceros. Bacteria appeared in the Proterozoic era (2500-541 million years ago). Trilobites appeared in the Cambrian period (541-485 million years ago). Lizards appeared in the Jurassic period (201-145 million years ago). Rhinoceros appeared in the Neogene period (23-2.6 million years ago). Thus, the choice D is the right choice.
