Wolves have a pelvis that was needed to have their legs connected to their bodies. Since they have evolved into whales, losing their legs to swim better, they no longer need a pelvis, but they still have it in their body. This structure, the pelvis, is no longer necessary for a whale, making the pelvis a vestigial structure for a whale. A human's vestigial structure is the appendix.

What is the term for a functionless anatomical structure that is evidence of an organisms' evolutionary past?

What is a vestigial structure and what organ in the human body is one?
A vestigial structure is one that no longer appears to service a purpose in maintaining homeostasis. An example is the vermiform appendix.
What is the vermiform structure is attached to the large intestine and is considered a vestigial organ?
The appendix.
What describes one-useful structure?
vestigial hope this answers your homework cause sometimes i do this with science :)
How are vestigial structures not removed by natural selection?
Yes, because vestigial structures can be harmful. For example, some humans are now born without an appendix which ensures they will not be killed via appendicitis. Having a smaller expression of a vestigial structure, like having a smaller appendix, saves on the energy wasted in maintaining an unneeded structure.

Is DNA a vestigial structure?
No. DNA is not a vestigial structure as it has not ceased to function
Human tailbone is an example of what?
I believe this sort of structure is called a vestigial structure (a left over remnant). The appendix is another vestigial organ.

How do you define vestigial structure?
Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
