Evolution in the 21st Century
I often wonder what people define as "evolution" in today's world. I have two conflicting opinions that I can't decide between:
1) The discovery and implementation of modern medicine has thwarted natural selection, keeping natural selection from pruning out the weaker members of the human race and keeping the human race from evolving into a superior form. If nature took its course, eventually genetic diseases, cancer, etc. would run its course, leaving the stronger humans to survive.
OR
2) Modern medicine IS part of today's evolutionary process. Survival of the fittest is now defined by those who can afford the treatment to stay alive and strong. Americans, for example, are comparatively wealthier than those in third world countries, thus Americans can maintain healthier lives and longer lives, while the destitute in other countries die in droves.
Which side do you fall on in this complex question? Or are there other takes on the subject?
