What else can I help you with?
This type of structure has no clear function in some modern species?
Vestigial structure. These are remnants of organs or anatomical features that had a purpose in ancestor species but no longer serve a clear function in modern species. Examples include the appendix in humans or the hip bones in whales.
What does vestigial structure describe?
They may have had an important function in the past.
What does a vestigial structure mean?
Vestigiality describes homologous characters of organisms which have lost all or most of their original function in a species through evolution. These may take various forms such as anatomical structures, behaviors and biochemical pathways
When extreme temperature changes a protein's shape so much that it can no longer perform its usual function?
denaturation
Why do vestigial structures still exist in spite of natural selection?
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.
What best describes vestigial structures?
They may have had an important function in the past.
What is the term for structure that has no use in an organism?
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
How do vestigial structures work?
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.

What is a vestigal structure?
A vestigial structure is a physical characteristic of an organism that has lost its original function through the process of evolution. These structures are remnants of traits that were once useful to the organism's ancestors but are no longer needed in their present form. Examples include the human appendix and the wings of flightless birds.
When extreme temperature changes a protein's shape so much that it can no longer perform its usual function?
denaturation
The pelvic bones of modern whales no longer function like the pelvis of a land animal and are an example of?
vestigial structures.
What is vestigial strucutures?
A structure in an organism that serves little to no use. Vestigial structures are degenerated and range from slightly harmful to useless to slightly useful. They are remnants of an organism's evolutionary past.
Why are vestigal sturctures considered critical evidence of evolution?
Vestigial structures are considered critical evidence of evolution because they are remnants of organs or structures that have lost their original function through the process of evolution. These structures provide insights into an organism's evolutionary history and support the idea that species have changed over time. The presence of vestigial structures suggests that organisms have inherited traits from their ancestors, even if those traits are no longer useful.
What are structures that have no apparent function but resemble structures of presumed ancestors called?
These structures are called vestigial structures. They are remnants of ancestral features that no longer serve a clear purpose in the organism's current form. Examples include the human appendix and whale leg bones.
