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.

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 vestigal organs support evolution?

Vestigial organs are remnants of structures that were once functional in an organism's evolutionary past but are no longer needed. The presence of vestigial organs provides evidence for evolution by natural selection, as they demonstrate how organisms have changed over time in response to their environment. These structures support the idea that species have evolved from common ancestors and help to illustrate the concept of descent with modification.


Are flippers of seal vestigial organs?

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.

What do you call a body part that loses it function through evolution?

A body part that has lost its function through evolution is typically referred to as a vestigial structure. These structures are remnants of organs or features that were functional in the organism's ancestors but no longer serve any important purpose in the current organism. Examples in humans include the appendix or tailbone.


How many vestigial organs are there in the human body totally?

There are several vestigial organs in the human body, including the appendix, wisdom teeth, and the coccyx (tailbone). The exact number of vestigial organs may vary depending on interpretation and definition.


Do plants have vestigial organ?

No, plants do not have vestigial organs. Vestigial organs are remnants of structures that were once functional in evolutionary ancestors but are no longer needed. Since plants do not have a common ancestor with animals, they do not have vestigial organs.
