Re: If we came from monkeys, why don't we have tails?
I'd be glad to explain. Over long periods of time, during the evolution of man from our common ancestor (most probably a primate,) there was no longer any need for a tail. I presume primates had used it either for balance or for gripping onto trees, as they are normally portrayed to do.
If you understand the concept of evolution, mutations. Well, the same mutations which have provided primates with tails could have reversed the effect. Why, do you ask? Because, as I've mentioned above, we had no need for extra balance (due to the fact we began to balance as bipeds without its use) nor did we need to climb up trees. With this said, a tail became absolutely useless for our species over time.
So, how did we actually lose the tail? Natural Selection: the tail became a useless appendage, so those who had the opportunity to receive the genetic mutation which shrunk it, had less weight to carry, and therefore had a higher chance of survivability. Eventually, those who did not have this mutation died off, unable to fend for themselves against the ever-changing world (also affected by evolution at approximately the same rate as us.) This process repeated itself until the tail existed no longer.
Hope this helps answer your question.
