Every human being and animals have that instinct of the survival of the fittest imbibed in them. It is really an important instinct with out whrich no living beings can survive. I heard this term by Charles Darwin in 7th std in Biology. But it is more of sociology now. When I talked with my husband about the political issues at present in Tamil Nadu(my state) , I asked this question to me. I came to a conclusion that this instinct of survival is present in every human being, not only it is seen in politics. This instinct is good as much as it doesn't harm others. But once it crosses the border there will be confusions. I wish to get inputs.
