Vestigial structures have no current function. Vestigial structures.
The appendix is our vestigial structure.
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.
Two structures (in humans) that are thought to be vestigial are the coccyx (tail bone) and the appendix. Although, they do have a purpose and are not seen as vestigial anymore.
Vestigial structures are the expressed genetic remnants indicatory of a species evolutionary past. In humans one such vestigial remnant is the coccyx, which were once part of tail structures in our primate ancestors.
Vestigial structures are eyes of cave-dwelling salamanders
The assumption is that it wasn't always vestigial.
The tonsils and appendix.
Most of the "higher evolved" animals I can think of have a vestigial structure or two. The most common example given is of the vestigial leg structures that can be found in the back of whales. Ostriches can't fly so i think their wings are considered vestigial. Humans have a vestigial tail bone.
Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
Tailbones, tonsils, appendix,
Yes you just did
its a body
Many species have vestigial structures, especially in the animal kingdom. Two good examples are the vestigial legs in whales and some snakes. This is clear evidence that whales and snakes are descended from creatures that had functional legs. This is strong evidence of evolution, since there is no other plausible explanation, religious or scientific, for vestigial structures.
