Have you ever wondered why all mammals have a tail, but man does
not? 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
