What if humans had tails?
Tails would play a role in how humans maintained balance, depending on how long they were. Sports and hand-to-hand combat would be dramatically different. Tails would be sexualized. Tail length and girth would become a major factor in how males were perceived and “tail envy” would be ubiquitous.
How did humans lose tails?
Losing the tail fin was strike one. Strike two happened once human ancestors lost what remained of their bony tail to accommodate upright movement. In both fish and humans, however, we can still see the remnants of the bony tail buried in our lower backs — the coccyx or tailbone.
Can humans grow tails?
When a human grows a tail, it’s known as a human tail or vestigial tail. Most humans grow a tail in the womb, which disappears by eight weeks. The embryonic tail usually grows into the coccyx or the tailbone. The tailbone is a bone located at the end of the spine, below the sacrum.
Did humans have a tail?
Humans do have a tail, but it’s for only a brief period during our embryonic development. It’s most pronounced at around day 31 to 35 of gestation and then it regresses into the four or five fused vertebrae becoming our coccyx. In rare cases, the regression is incomplete and usually surgically removed at birth.
