Normally, animals can adapt to changes in their environments with corresponding changes in their behaviors. One well-studied example is what’s called “fear extinction learning.” Animals can be taught to associate harmless things like a sound or lights with a negative outcome. But, if that association changes over time, they can also forget it.
The Aldabra white-throated rail, a flightless bird that lives on its namesake atoll in the Indian Ocean, doesn’t look like anything special at first glance. But the small bird has big bragging rights, because it has effectively evolved into existence twice after first going extinct some 136,000 years ago.
