The question may sound absurd to many, given that human beings regard ourselves to be the greatest animal on this planet, but totally reasonable to me. Animals, over the years, have evolved to adapt to the environment,which gave them various physiological features. For example, bat developed a radar system to navigate its way in the dark night. Scientists studied this feature and, basing on this result, invented the global positioning system, creating numerous benefits for human beings, ranging from aviation to telecommunication. So I am sure that there are many more to make use of. On another level, we also can learn the secrets to happy lives from animals such as dogs who are wagging their tails all the time. Dogs always live at the present, and they never worry about the future, but human beings seem to have endless worries for tomorrow.
