Of all known creatures, man is truly unique and special due to the following attributes.
1. The human brain has qualities that have no parallel in the animal world. The evidence of this is man's outstanding mental capabilities.
2. Man is the only creature that is fully bi-pedal. He can walk upright due to the special structure of his spine and therefore his hands are not necessarily required for locomotion but are free to carry out other purposes.
3. Man is the only creature that possesses the faculty of speech. His creative communication by means of his vocal system is utterly different from those that other animals have.
4. Man is the only creature that can outstandingly express emotion. Some of the animals seem to be able to do the same but they can only do so to a very minimal degree as compared with man.
The thesis of the Declaration of Independence was that the colonies deserved their independence, since the right to three basic things life, liberty, and the pursuit of happiness came from a power higher than man.
