Animals That Evolved to Survive Enemies That No Longer Exist

Animals That Evolved to Survive Enemies That No Longer Exist Some animals are still carrying defenses built for predators that disappeared thousands of years ago. In this video, we look at species shaped by extinct enemies, animals that evolved speed, armor, strange behavior, or extreme caution to survive predators that no longer exist. From pronghorn outrunning ghosts of the Ice Age to island species still showing traces of ancient evolutionary battles, these adaptations tell us what their ecosystems used to be like.
