Using the example of the pronghorn and lion, explain the concept of a relict behavior.
Relict Behavior
In general, animals act in ways that help them to survive within their specific habitats. However, sometimes an animal species may display a behavior that no longer serves a clear purpose. The original purpose for the behavior may have disappeared long ago, even thousands of years before. These behaviors, known as relict behaviors, were useful to the animal when the species’ habitat was different: but now, because of changed conditions, the behavior no longer serves its original purpose. Left over from an earlier time, the behavior remains as relict, or remnant, long after the environmental circumstance that influenced its evolution has vanished.
