Past use of appendix
What is the proposed purpose for the past use of the appendix?
Presumably the appendix is a useful organ for lower animals. Any zoologists out
there know the answer?
In other animals the appendix is huge and is called the caecum, or sac,
because it is a dead-end structure. In rodents, is houses bacteria that have enzymes
that help the animal digest plant material. In other mammals or primates, it is thought
to serve a similar function in the digestion of raw meat.
