Darwin's Theory of Evolution by Natural Selection. More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.
In other words, the Darwin theory says natural selection will take care of eliminating the weakest and dumbest of any species depending on the environmental conditions.
September 11th is around the corner. Its also the dreaded day where I head off to Kalifornia for a few weeks. But don't worry, people have very short memories. Sometimes something as insignificant as the Sept 11th anniversary is a good place to see how many of our fellow citizens and humans will be left if something drastic was to happen again.
Proves people have very different priorities about life. Especially young people in some place like liberal Kalifornia where the focus is on 'having a good time' and not being too serious about anything that might be too serious (pun intended).
