A vestigial trait (i.e. organ, appendage, etc) is a remnant part of an organism that historically was very important but evolutionarily is no longer needed. For example, the tailbone on humans is considered vestigial because it serves little to no purpose, although at one point it most likely connected to a tail.
Another example is the dew claw on a dog (the small, dangling claw on a dog's front paws). Clearly there's no use for it today, but at one point it may have served an important purpose for survival.

The opposite of vestigial organs would be functionalorgans.
Vestigial organs are organs that used to have a purpose or function. They are vestigial because they no longer perform that function, but some vestige of them remains.
vestigial organs like the appendix which is vestigial in man
there are 90 vestigial organs in human body
vestigial organs do not PROVE evolution existed but they are an evidence of evolutioin existing
The appendix is the best example of a vestigial organ.
Vestigial organs/limbs mean that there was an ancestor of the creature that once had non-vestigial, usable organs/limbs. This implys that the creature evolved from something that once needed such organs/limbs to survive, but now the species no longer needs the vestigial organ/limbs and it has lost it's use/size.
Organs that are not used for their original purpose!Vestigial organs.
Yes, like all animals, wolves do have some vestigial organs. One good example is the dew claw.
no. they are analogous organs
Yes, as they are unneeded.
No. Vestigial organs are organs that were previously useful to an animal, but, even though they are no longer useful, remain because evolution hasn't taken them away yet. Seals still use flippers.
Evolution is a slow process of trial and error. Vestigial organs are organs that once had a function in the ancestral body. They are no longer important, so the body puts less energy into developing them, but we still inherit these characteristics in our DNA. However, often organs that we consider vestigial still do serve some function, although we can survive without them.
Generally, they are called vestigial organs
The brain... for most people.

It's an organ that isn't used, but is still present in an animal's body. Here are some sentences.The appendix is a vestigial organ.An example of a vestigial organ is an emu's wing.Vestigial organs are evolutionary leftovers.
Vestigial organs.The correct definition is, organs that are no longer used for their original purpose.
