True evolution is a change in the structural or functioning ability of a creature to adapt to it's surroundings. The ability of humans to live longer is simply the building of technology to adapt to the surroundings. When I speak of evolution I'm not speaking of technological evolution but of the improvement in the physical body to adapt. You have to look at all the things involved. We have more diseases now than ever. The only reason they are lengthening the average lifespan is our technological means - antibiotics, vaccines, and sterile medical precedures. Also if you go back to early recorded history there were many who lived to a much older age than people currently do. It wasn't the average but there are fewer of those that reach that age now than before. We have not grown in any physical way to adapt. That is the basic evolution that must be observed.
