The human body's vital organs are having a serious team meeting—heart, brain, liver, lungs, kidneys all joining hands in a circle of biological importance. Meanwhile, the appendix shows up as a Teletubby, completely clueless about its purpose in the anatomical hierarchy. This is evolutionary biology in a nutshell! The appendix is basically that coworker who shows up to meetings but nobody remembers what they actually do. Once crucial for digesting cellulose in our herbivore ancestors, it's now just hanging out in our digestive tract like that weird vestigial party guest who refuses to leave after evolution's party ended millions of years ago.
