Human beings are animals, but we are different from other animals because of our ability to talk. However, we can also communicate in many other ways like other animals do. We send silent signals to each other all the time. A smile is a sign that a person is happy, we cry, scream, and sometimes even groan. The use of language makes it possible for us to work effectively with one another. It also helps us to plan ahead and do things that animals would find impossible to do. The ability to use language means we can argue, reach an agreement and explain our views to others. We can record our feelings, thoughts, and ideas. Most importantly, we can benefit from the knowledge of past generations and the information we acquire in our lifetime can be presented so that future generations may be able to make use of it
