Is the appendix a vestigial body organ?

The appendix appears to be a hold over from the days when our ancestors ate plants.

In other vertebrates, the appendix is larger than it is in humans and it is used to break down cellulose in plants.

In humans, the appendix is a small, withered pouch - which is attached to the intestines but is not involved in digestion. Thousands of people have their appendix removed each year and are not the worse for wear, which appears to indicate that we just do not need our appendix.
