Fish Evolution

Mural reads: Fish Evolution: Gills become lungs; fins become legs. Talk about bad timing. @*!*! News: Global warming rising oceans.

This mural is funny because the fish is annoyed that it just finished evolving to live on land, and now, the ocean habitat is expanding to reduce the land habitat. It also reminds viewers of humans' effects on nature (fish naturally evolved to life on land, but now humans have decreased the benefit of this trait).
