Can a Human Grow a Tail?
Humans are not born with tails, except in the case of a birth defect, and cannot grow one by choice. However, humans do have tails during their development inside the womb. Plastic surgeons are also capable of installing tail-like implants.
Although most humans are incapable of developing a tail, there is an exception. In rare cases, human babies may be born with a vestigial tail-like structure due to a birth defect in rare cases. From 1884 to 2014, only 23 cases were reported and documented in medical literature. Although not all cases have been reported, the condition itself is uncommon.
