Ichthyosaur Memes

Imagine evolution as the world's longest game of "just kidding!" First, some reptiles 250 million years ago were like "Land is overrated" and swam back to sea, becoming ichthyosaurs. Then 200 million years later, mammals pulled the same stunt with a dramatic "my people need me" exit, transforming into dolphins. Now we've got a professor warning the next generation not to make the same mistake—because clearly, these evolutionary U-turns are getting embarrassing. Nature's greatest flex isn't creating new species; it's convincing animals they made a terrible real estate decision millions of years ago.
