Resumen de Appendix. (Cover story)
The article discusses the origin of the vermiform appendix which is a long, slender cavity which is closed at the tip and branches off the cecum at the beginning of the large intestine. Topics include a brief overview of how the appendix functions in various animals including rabbits and koalas, why some plant-eating mammals have no appendix, and the evolution of the human appendix to function as a repository for beneficial bacteria instead of as a digestive organ.
