Vestigial Structures

Vestigial Structures

Vestigial structures  can be found in many different forms, whether it is an organism’s behavior, anatomical structure, or biochemical processes. Overtime time and development through a species’ life some part of the body, or some behaviors are far less needed than they once were in the past, but most times this unused trait does not disappear; it usually performs minimal tasks or is unused. Some examples of animals with vestigial structures are whales with fragmentations of leg bones in their fins, an elephant’s sixth toe, and a human’s “goosebumps” which is no longer controlled by will. All in all vestigiality in its state of being provides evidence on the existence of biological evolution.
