The appendix serves no essential purpose in human anatomy. It could therefore easily be argued to be an evolutionary remnant of some earlier form that did have an essential function.
However, arguments based on function are, at least to my mind, spurious at best. Much more significant are observations about the shapes of organs.

No, Charles Darwin did not retract his ideas of evolution. His theory of evolution by natural selection remains a cornerstone of modern biology and is supported by extensive scientific evidence.

No, of course not. Evidence does not prove evolution - it validates the theory.Evidence which Darwin had included limited fossils, and observed apparent speciation in birds.
Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.
The appendix is a finger-like appendage attached to the stomach which has become redundant in the evolution of humans. If an infection occurs to the appendix - a life threatening appendicitis will need a surgical operation. I believe it is one of the stomachs used by herbivores.
All species have the same genetic code.
Related species have similar embryos.
Many species have vestigial structures, especially in the animal kingdom. Two good examples are the vestigial legs in whales and some snakes. This is clear evidence that whales and snakes are descended from creatures that had functional legs. This is strong evidence of evolution, since there is no other plausible explanation, religious or scientific, for vestigial structures.
Embryos are used as evidence of evolution because they display striking similarities across different species during early development. These similarities suggest a common ancestry, supporting the theory of evolution. The study of embryonic development provides insights into the evolutionary relationships between species.
Fossil records, anatomical similarities among different species, and the observation of natural selection in action were some of the key pieces of evidence used to support the idea of evolution when it was first proposed.
Evolution
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.

There is no single piece of evidence that definitively disproves evolution. The theory of evolution is supported by a vast amount of evidence from various scientific fields, including genetics, paleontology, and comparative anatomy. Any challenges to the theory of evolution would need to provide substantial evidence and be subject to rigorous scientific scrutiny.
