The present strawberry poison dart frog on the left is shown with bright red and blue coloring to warn predators of its poison. It has suction cup fingers for gripping trees. On the right the frog is depicted as how it might look in thousands of years. It is in a burrow and it has claws on its fingers, this is because they must dig underground to stay safe from predators, stay damp and cool in the warmer climate, lessen their exposure to harmful ultraviolet rays, and find a better insect supply. The frog is slightly larger because it has developed thicker skin due to a wider rib cage, for larger lungs which help filter out polluted air. The frog's poison has become more lethal to better defend from predators that have developed a mild immunity to its poison, represented by the comparatively brighter color of its skin.
