The biologist might infer that at one point in history the animal's ancestors had this limb. But as time went by the ancestors used to limb less, therefore, shrinking the limb or completely getting rid of it.

Structures with no function that are remnants of an organisms evolutionary past are?
VESTIGIAL
Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
What is vestigal structure?
Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution.
What are 3 examples of organisms that contain vestigial structures?
among that three one is surely a human contain vestigial organ "vermiform appendix" the other two i don't know it exactly
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.
How do vestigial structures indicate that present day orgnaisms are different from their ancient ancestors?
I don't know lol
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 are structures that have no apparent function but resemble structures of presumed ancestors called?
Vestigial organs.
Structures with no function that are remnants of an organisms evolutionary past are?
VESTIGIAL
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.
Would vestigial structures make any sense if organisms did not evolve?
No, because the use now would be the use then which is not really vestigial.
Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
What is vestige?
Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution.
Why do vestigial structures persist in organisms?
The environment will not select for or against organisms that have a particular structure unless that structure affects the organisms' fitness.They are called Vestigial because they persist to exist.Additionally, evolution takes time, especially when something is not pushing it forward.

What is a vestigal structure?
Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution.
What are features a modern organism doesn't need but has inherited from it's ancestors called?
Vestigial structures. Sometimes put to other uses that they were not adapted for.
