Most people have heard about Darwin's theory of evolution. That due to survival of the fittest eventually elements that do not help the species thrive die out. Certain traits aren't bred maybe not on purpose, but because nature doesn't need them. The strong survive and the weak don't.
Welcome to the modern ages where in todays world atleast for humans this no longer takes effect (well it might still be in some third world countries). It's true. With modern medicine the weak and stupid can survive the mistakes that would normally weed them out. No, I'm not saying that specific people are stupid... I don't know everybody, but there sre some people that you personally know I am sure that did something they lived through because of modern technology that would have/should have killed them off.
So what happens when they survive? They breed and while their child has the potential to avoid the same mistakes and be brighter than their parents it doesn't always work out that way. Is stupidity genetic... some people look for the smartest person they can find to breed with looking ultimately to have children that exceed in the future (fortunately for me, my exwife did not and neither does my current fiancee or I'd be SOL).
In theory first world countries like the United States, Great Britain, France, the Soviet Union, China and Japan all are working with a stable genetic program that will not have much pressure from nature for evolutionary changes. Third world countries where surviving because of lack of food and other natural hardships allows nature to do its thing. The greatest advances to the human species genetically speaking will be there. People that require less food and water to survive. People that due to warfare in their country will seem to have heightened senses so that they can survive and see the dangers out there before it sees them. They will have stronger immune systems if they survive.
I don't think we as a species will notice these changes. They will be subtle and due to our advanced technology and access to medicine those of us in the first world countries will still live longer then them and have a higher quality of life.
Civilization stops evolution, but I would not trade my life with all of its wonders and those of my children to become more evolved. I like my computer my car and all the other great things we have. Have fun and be great.
