My guess is we will seperate more into groups that do the things. Like maybe one group will stay stronger and take care of the food supply, or build structures. Then the other parts of society, like the business area, will evolve more weaker but more intelligant for the paticular use of the position. People that work in hot areas like a steel mill may become more resistent to heat and develope a much tougher strand for skin. Like creating custom people to fill each postition prefectly, but a the econimy constantly changes there will always be a different road to improving. A "perfect" human isn't really possible, as that would require more than the body could handle in ways of pressure, different skills and mental ability. Well, actualy if you take the plant term "perfect" then its possible, I mean through genetics we could make a human with both parts for reproduction...
