The Amazon river dolphin, or pink dolphin, lives in the rivers in rainforests. But due to global warming and deforestation, their habitat may change to that of a desert with limited water. Within the next hundred years or so, their original habitat may no longer exist. Because of this, I believe that river dolphins may evolve to have legs similar to how the ancient whale ancestor, the Pakicetus, evolved from having legs to having fins.
