An offshoot of evolutionary thinking is the relatively new field of sociobiology. In other words, our behaviors are the result natural selection as much as our physical characteristics. Ultimately, then, from this perspective, all behavior is selfish. Everything we do is geared toward furthering our own survival and the production and the survival of our own offspring. Our behaviors have been selected over time to aid in our survival and reproduction and that's all.
Evolution is a wasteful, inefficient process.
Carl Sagan says that the fossil record is filled with the failed experiments of evolution. Evolutionary history is littered with dead-ends and false starts. Stephen Jay Gould characterizes the nature of the evolutionary process as one of contingency history. Organisms survive primarily by chance rather than some inherent superiority over other organisms. A person's character is reflected in his or her work.
