Your appendix. The hips and vestigal legs of modern whales. Mutation-Natural Selection explains these in a straightforward manner. No other theory does.
Your appendix.-you-"
Wrong. Doctors have found uses for both the appendix and the tonsils. Your statement is an example of the know-nothingism of the evolutionists:
"For years, the appendix was credited with very little physiological function. We now know, however, that the appendix serves an important role in the fetus and in young adults. Endocrine cells appear in the appendix of the human fetus at around the 11th week of development. These endocrine cells of the fetal appendix have been shown to produce various biogenic amines and peptide hormones, compounds that assist with various biological control (homeostatic) mechanisms. There had been little prior evidence of this or any other role of the appendix in animal research, because the appendix does not exist in domestic mammals.
