Hey mate here is your answer》》
The short answer is that twenty or twenty-five million years ago when the apes diverged from the old world monkeys, they lost their tails, and so we don’t have tails simply because all of our ancestors since the Miocene have been without tails and we have inherited this trait from them.
More interesting perhaps is why those ancient ancestors lost their tails, and that is uncertain. Perhaps since apes have tended toward larger sizes and bigger brains than monkeys, they have had to use different kinds of tree climbing strategies than monkeys do, and tails tended to lose whatever their original purpose was due to that. Using a tail as a rudder may be meaningful for a leaping monkey, but not for a brachiating ape, or something like that. Perhaps it was an ancient random mutation, and nothing more than that. Whatever the original reason was, evolution works on the needs of the moment, and all descendants are saddled with whatever re-designs happened to ancestors’ bodies long ago.
Finally, of course we do have small tail bones at the end of the spinal cord, so it never did completely go away.
