honestly why do you guys need a rear camera... kill the kid that was running behind your car... evolution of the fittest

The term is "survival of the fittest". And since I'm in a cranky mood tonight, I think that you should also be aware of the following:
Why am I an moron if I advocate Social Darwinism?
Darwin's theory states that in any population there are variations within individuals. If, due to the interaction between the individuals and the environment, the variations in one subgroup of a population provide an advantage towards reproduction, those traits are more likely to be carried on to the next generation. Through subsequent generations, if those variations continue to be advantageous, those characteristics will become more common in the population as a whole.
That's all he says.
Darwin had no concept of genes or genetics at the time that he wrote The Origin of Species in 1863. Gregor Mendel was in the midst of doing his pea plant experiments at the time, but Mendel's work did not really come to light until the beginning of the 20th century, long after The Origin of Species was published.
Furthermore, Darwin does not say that this variation confers some sort of "superiority" to any group of individuals to others in the group, or implies a "fitness" to an individual's right to survive. This misapplication of Darwin's theories to society has caused a lot of trouble in the past, including the justification of the colonial system, laws that discriminate on the basis of race, and the Holocaust. In fact, the phrase "survival of the fittest" does not come from Darwin, but from one of his contemporaries, Herbert Spencer, one of the first "Social Darwinists", in an attempt to justify the colonial system, and the European domination of much of the rest of the world.
You can read Darwin's original work at this website. Nothing like looking at primary sources to show how much we all misunderstand other people's thoughts.
