The appendix, an extension of the large intestine appears, although this is debated, to have little function in humans. What is the appendix an example of in terms of evidence for evolution?​

Vestigial organ

Explanation:

Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.

The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.
