Detailed explanation-1: -Vestigial organs are the organs which were functional in their past but lost its function during the course of evolution. Human tailbone is also known as coccyx. The coccyx is a remnant of a tail from our ancestors.

Detailed explanation-2: -Called “vestigial structures", these things no longer retain a specific purpose but remind us of where we’ve come from. One example is the tailbone – known as the coccyx. Humans obviously don’t have tails to help us move through the treetops and balance on long branches, but a common ancestor did.

Detailed explanation-3: -Tail bone in mammals is vestigial while other animals use their tails for balance, when humans began to walk, the tail became useless and evolved into the coccyx (united vertebrae).

Detailed explanation-4: -A “vestigial tail” describes a remnant of a structure found in embryonic life or in ancestral forms. [4] During the 5th to 6th week of intrauterine life, the human embryo has a tail with 10–12 vertebrae. By 8 weeks, the human tail disappears.

Detailed explanation-5: -Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds.
