How did evolution happen then when the life expectancy was well below 50 years?

Human evolution is grinding to a halt because of a shortage of older fathers in the West, according to a leading genetics expert.
Fathers over the age of 35 are more likely to pass on mutations, according to Professor Steve Jones of University College London.
Speaking Tuesday at a UCL lecture entitled "Human Evolution Is Over," Professor Jones will argue that there were three components to evolution — natural selection, mutation and random change.
"Quite unexpectedly, we have dropped the human mutation rate because of a change in reproductive patterns," Professor Jones told The Times.
"Human social change often changes our genetic future," he said, citing marriage patterns and contraception as examples.
Although chemicals and radioactive pollution could alter genetics, one of the most important mutation triggers is advanced age in men.
This is because cell divisions in males increase with age.

Evolution? What evolution? ;)
I guess his message is we can’t screw around any more.....
BTW Devo is throwing a concert for Obama. Couldn't be more fitting.
Professor Steve Jones of University College London.
is a Moron.
man is not Evolving, and never was evolving.
Well this news would explain why Congress is so stupid.
I was a noncombatant during the Sexual Revolution, but this sounds like a great cause to save the people.
I wonder if Al Gore will come up with sexual ration coupons to give preference to old guys with small carbon footprints?
Let’s assume evolution, then we’ll say that it’s stopped.
Can’t look at any other possibilities, like, we humans were originally created perfect, “fell”, then degenerated (LOST genetic information, not GAINED) over the generations to what we are today - genetically crippled and unable to adapt,
like poodles or dachshunds compared to their wolf ancestors.
They finally came up with an excuse as to why we haven’t been evolving lately.
Even if you believe we are all the descendants of Noah's family, then you propose that human evolution has happened even more rapidly than geneticists postulate.
So how did Africans become African and Europeans become European and Asians become Asians if not by evolution through natural selection of genetic variation?
How?
Pee Wee Herman: "You know what they say, 'Big shoes . . . big feet'."
I mean look at dems they are in the process of reverse evolution because they are turning in slim and primordial muck as we speak.
But undesirable mutations haves little or no chance of becoming the norm.
Well, duh ... I’M here! There’s no prospect of further improvement in the species.
and “desirable” mutations are so rare as to not be of any benefit, species-wide.
I often look at my fellow humans and wonder if it ever started.
