Then, how do you explain VESTIGIAL ORGANS?
The VERMIFORM APPENDIX is a vestige of the cecum, an organ that may have been used to digest cellulose by humans' herbivorous ancestors.[citation needed] Analogous organs in other animals similar to humans continue to perform that function, whereas other meat-eating animals may have similarly diminished appendices. The modern functionality of the appendix is still controversial in the field of human physiology, although most scientists and physicians believe that it has little or no function.....
The COCCIX, or tailbone, is the remnant of a lost tail. All mammals have a tail at one point in their development; in humans, it is present for a short time during embryonic development. The tailbone, located at the end of the spine, has lost its original function in assisting balance and mobility, though it still serves some secondary functions, such as being an attachment point for muscles, which explains why it has not degraded further.
