Men are a form of animals just like other species. They are the most intelligent and hence they are known as the Homo sapiens and are self-styled as the noble creatures. This is legitimate due to a number of differences from the dumb animals. First it is the superior brain human beings possess. Human brains have long memories, keen in the abstract thinking equipped with a priori and a posteriori thinking function together with keen logic based on inductive and deductive process. Men are capable of altruistic acts whereas animal’s acts may be based more on instinct. Men arguably have keen minds and delicate souls. Animals may possess the above attributes but much lesser in degree. The second attribute men have over animals are the ten fingers which allow them to manipulate for tools making led by the superior brains. Monkeys may have fingers but do not have the kind of brains human beings have. Tigers, lions, bears have paws but not fingers. Third, men learn to stand and walk erect. Men evolve from walking with legs and hands to stand erect which would free the two hands to make things with the brains apart from having a far vision. The Homo erectus start civilizations by making tools for hunting and for fighting. The fourth element is the vocal cord of the Homo sapiens which allow them to make sounds of various kind and tones. This will enable them to create speaking language which subsequently through the brains, written language with signs depicting pictures or sounds. This lies the difference of the two types of species.
