Why Don’t Men Have Tails?

All species of animals, including man, of course, have evolved very gradually over millions of years. In this way, each animal strengthens and improves those parts of its body that are particularly useful, and the various parts that are not so useful diminish, or are adapted to a changed environment. This evolution happens very slowly, and changes can only be seen over numerous generations. In four legged animals, tails are very important to maintain balance. In many cases, tails are used almost as another limb, like when monkeys swing through the trees. However, Men and apes, have no useful need for a tail. As a species that lives on land, Man doesn’t  need tails for hanging on tree brances, and since we don’t fly or leap, we don’t need then for balance either. As a matter of fact, a smalll, very rudimentary ‘tail’ can be founded at the base of our spines. It’s called the coccyx, or tailbone, and it’s all that left of the human tail. It’s just too small to p oke out behind us, so we don’t know it’s there, and it does not help us at all with balace or movement.
