Normally long life means you can take care of the offspring, but since offspring will survive even if you don't, this aspect is not selected for.
The implications of this are not good, because we are selecting for the traits least desirable in modern society.
People who delay births, and thereby demonstrate health later in life have far fewer children than those who give birth early.
Additionally there is an unfortunate trend for people to delay children until their "career" is settled. Which means that people with simple careers (manual labor and the like) have far more children than those who's careers take longer (and are presumably more intelligent), and it's those more complex jobs that are in demand right now.
An interesting take on this: http://www.economist.com/sciencetechnology/displaystory.cfm?...
No. The article says "...women who conceive earlier in life and reached menopause at a later age, all had more offspring" (emphasis mine). So it's trying to maximize for child-bearing years, on both the early and late sides.
I call baloney on this. Where's the citation of anyone saying that?
Our rationalization skills are evolving though. We now know many more people to point our fingers at.
