Ah yes, parrot Darwin's theory like a good boy. This theory by the way is one of the most idiotic theories I have ever come across, I will show you why it is flawed and in fact a good word to describe it's fallaciousness is "altruism".
If the 'survival of the fittest' theory was in fact a valid one, why do we have altruistic acts in this world of ours. I am talking about acts where people risk their lives, wealth, and happiness for the well-being of others. Altruism is the truly selfless giving of oneself to others with absolutely no secondary motives.
Oskar Schindler placed his life in great danger by sheltering more than a thousand jews from Nazi extermination during WW2, and ultimately died penniless. This person did so out of a conscience. He did not do so to survive, or to better himself, or even to protect his genes. He helped perfect strangers because he thought it was the right thing to do. so much for the 'Survival of the fittest'.
