Why evolution often involves losing features rather than gaining them
In short: We often imagine evolution as a steady climb toward more complex features. This video explores how natural selection can actually lead to the disappearance of traits that no longer serve a purpose for survival.
The video challenges the misconception that evolution is a continuous chain of progress where organisms only acquire new, complex abilities. Instead, it examines how traits—such as a potential third eye in human ancestors—can be lost if they no longer contribute to an organism's ability to survive or reproduce.
