Question

examples of vestical organs..and explanation..

Answer 1

sorry for long answer -

Vestigial organs are commonly described as organs that are no longer used, and havetherefore been reduced by evolution until they are mere remnants without function. Examples include things like eyes in blind cavefish.However, this is a misunderstanding of vestigiality; or rather, it is only one particular case. There's no rule that says that a vestigial organ must be non-functional. All it means is that the organ is a vestige of some other structure that shows clearly that it used to have a different function, whether it is now functionless or has been exapted to servea new function. For example: humans do not have tails, so our tailbones are clearly vestigial: they're precisely homologous to the bones at the base of the normal mammalian tail. But while we don't have a tail, the bones can still serve to anchor muscles. Or another example: the vermiform appendix is a vestigial organ, may be reduced vestige of the caecum, a pouch where herbivorous mammals have bacteria to break down cellulose; but the human appendixdoeshave functions other than killing you, playing a role in the immune system. Boas and pythons have so-called pelvic spurs, tiny vestigial legs -- obviously no longer used for locomotion, but exapted to help clasp to the female during mating.So a vestigial organ issimply an organ which can be clearly seen as a reduced and modified version of an ancestral organ,no longer serving the same purpose; it mayor may not serve another purpose in itsvestigial form.

appendix and wisdom tooth are example of vestigial organ appendix is used to digest the raw meat by our early ancestors and wisdom tooth is used to eat the raw meat
