No, let's discuss how the appendix or tonsils or other FORMERLY 'useless' organs were used as BOGUS examples, out of complete ignorance, same as you have done above. Let's discuss that.
Non-sequiter. I did not mention the tonsils or appendix, nor did I say anything about any part of the anatomy being useless. I was talking "engineering problems." Now, instead of going off on a tangent, would you care to address the issues already presented, or do you want to stick with irrelevancies?
What purpose does the appendix serve?
