Often I ponder on this question and I find that we are exceptionally different from other creations of the world and yet we have affinity with them. Man has 'Intellect' which makes us the best of all. Now with the help of this intellect we can think and decide two things- good and evil. To accept and to work on it we are dependent on our culture of our society and family as well. For example, people in India are habituated of living in a join family still. I think, that is a plus point for them to enhance power of tolerance and accept all situations with their own identity and value. On the other hand, I find the youths of other places are void of this and therefore there has emerged a totally different culture mixture of man and animal.
Second we have 'speech' which is unique and not other creature has. We are able to express our feeling with even a person of any corner of the world. We have written down our thoughts in the manner of various media and taken to the every corner of the world and thus we feel affinity to each one of us. It does not happen in the case of animals.
Third thing that we have two legs and two hands rather that having four legs by animals. They are also vital parts of our body to serve the needy and to work for the betterment of the nature with care.
Yet, now a days, people seem to be imitating more to the culture of animals and try to merge with them. Yet we need to serve them considering them a part of this world living together but not to adopt their culture like having sex with anyone at any time whether I know or not, liking and disliking instead of loving, spreading everything all around the world not giving a second thought how it will effect on others, affecting zero tolerance with others, trying to show others that we are the best, spreading hatred.
Some of the above vices of man are not found even in animals, thus I think in some aspects we are inferior to them.
