The Short Answer

Sometimes enough mutations occur such that something happens in the population. Doesn't have to be meaningful; evolution does not "think". Same as why you still have an appendix even though you don't use it. Or why we we don't have keen senses of smell like some of our mammalian cousins. We still retain the tailbone though, but for those who have it exceptionally pronounced in our modern world, they try to correct it with surgery. Otherwise, they can't sit properly on chairs – the "tail" ain't got any advantages for them without the ability of its control.
