The 'Extinct Bird Re-Evolved Itself Back Into Existence' meme originated from scientific headlines reporting on the Aldabra rail, a flightless bird that went extinct but reappeared through a process called iterative evolution. The internet quickly turned this rare biological event into a symbol of persistence, unwanted returns, and the inevitable cycle of life. It is commonly used to describe defunct apps making a comeback, fashion trends returning from the 90s, or people returning to their toxic habits after promising to change. The meme perfectly blends genuine awe with the dry humor of something simply refusing to stay dead.
