Evolution

Are we still evolving? Depends.

For those of you who do not plan to have children, read my following argument.

The heart of evolution rests upon the notion, "survival of the fittest." Now that you have survived, and as long as you can provide your children with enough care, it is your obligation to reproduce; otherwise there is no meaning to evolution. The worst case is that the healthiest/smartest/wealthiest nowadays are among the most reluctant to have offspring. Imagine what would happen after several generations. Yes, the best genes survived, but they disappear once people die. Only inferior genes have a chance to get reproduced and pass along. Evolution works backwards. To say that we are going back from humans to apes would be an exaggeration, but it might be the case that one day we find our world filled with people who are less fit.

The extreme evolutionist might go on and argue that we should never cure inherited diseases, or at least should ask people infected with these diseases not to have children. This helps the evolutionary process by eliminating the "bad" genes. However, this becomes more like a moral issue. The Oath of Hippocrates, i.e. the "doctor's oath," clearly states that "into whatever houses I enter, I will go into them for the benefit of the sick." The doctor is obliged to cure all diseases whenever he is able to. Everyone has the right to live and the right to give birth to children. If they are deemed not to fit the world, natural forces will come into play. It is not you or me or the doctor who makes the decision.

Again, if you have the ability to raise a kid, it is not your decision to have one or not; it is your natural obligation since first signs of life appeared on Earth 3.6 billion years ago. Evolution is a continuous process: it should never be altered by human beings, the species that benefit from it the most.
