Want this question answered?
VESTIGIAL
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)
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.
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.
among that three one is surely a human contain vestigial organ "vermiform appendix" the other two i don't know it exactly
I don't know lol
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.
Vestigial organs.
VESTIGIAL
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
No, because the use now would be the use then which is not really vestigial.

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.
