Modern life's pressures may be hastening human evolution (Human Evolution Speeding Up)
McClatchy ^ | April 8, 2009 | Robert S. Boyd

Posted on 04/08/2009 6:19:32 PM PDT by GOPGuide

It's even conceivable, he said, that our genes eventually will change enough to create an entirely new human species, one no longer able to breed with our own species, Homo sapiens.

"Someday in the far distant future, enough genetic changes might have occurred so that future populations could not interbreed with the current one,'' Sussman said in an e-mail message.

snip

It's also the topic of a new book, "The 10,000 Year Explosion,'' by anthropologists Henry Harpending and Gregory Cochran of the University of Utah, Salt Lake City.

"For most of the last century, the received wisdom in the social sciences has been that human evolution stopped a long time ago,'' Harpending said. "Clearly, received wisdom is wrong, and human evolution has continued.''

snip

When he was asked how many genes currently are evolving, Harpending replied: "A lot. Several hundred at least, maybe over a thousand.''

Another anthropologist, John Hawks of the University of Wisconsin-Madison, said, "Our evolution has recently accelerated by around 100-fold.''

A key reason, Hawks said, is the enormous growth of the world's population, which multiplies the size of the gene pool available to launch new varieties.

"Today, beneficial mutation must be happening far more than ever before, since there are more than 6 billion of us,'' Cochran said.

The changes are so rapid that "we could, in the very near future, compare the genes of old people and young people'' to detect newly evolving genes, Cochran said. Skeletons from a few thousand or even a few hundred years ago also might provide evidence of genetic change.

"Human evolution didn't stop when anatomically modern humans appeared or when they expanded out of Africa,'' Harpending said. "It never stopped.''

Actually I think technology would cause evolution to slow. We aren’t being wiped out by diseases the way we would be without medicines.

On the other hand I suppose easier lives could drive evolution in a different direction and not a good one.

“Human Evolution Speeding Up”

Evolution or adaptation?

No, as population and mobility increases, so do the number genetic combinations.

At least microevolution, I don’t want to get into a debate over Macro (Personally, I have suspicions about whether abiogenesis is possible)

Evolution Speeding Up or Intelligent Re-Design?

Good point. Also an easier life “should” lead to greater brain development but I’m not so sure that many don’t retard that all by themselves.

* Muffin Top: Tummy fat on women that bulges out when snug low-rise jeans or short skirts are worn.

And a few other new evolutionary traits that modern society's pressures may be hastening:

* Doughnut: A circle of fat around the navel, which represents the doughnut hole.

* Cankles: Fat that fills in and eliminates the curve between the calf and the ankle.

* Wings: Also called bra fat, it refers to the rounded bulge above and below the bra strap.

* Banana Fold: The ridge of fat high on the leg and just below the derrière.

* Chubb: Fatty kneecaps.

Brain development has not improved with increased nutrition, at least for the past 100 years.

While height has increased in Western nations over the past 100 years, skull volume has not.

So we’re adapting quicker to changes in our environment because changes in our environment at happening quicker; and this the author believes will create “an entirely new human species, one no longer able to breed with our own species, Homo sapiens”?

Is this a joke-obligatory thread?

OK, here's mine: Does this mean Idiocracy is more or less likely?

I've come across Cochran before, quite a sharp fellow. I suspect his book's thesis is a threat to the regnant, superficial theory of human equality taught by my anthropology prof. I'm surprised Cochran's not more controversial.

Not only technology, but social policy. The fittest no longer reproduce the way they should. The least fit are subsidized to do so. I would not be surprised if we see reverse evolution.

“that future populations could not interbreed with the current one...”

Ten-thousand year old people aren’t supposed to sleep with 20-year olds anyway. That’s just gross.

Exactly. If anything we are devolving.

Look at the segments of the population that is procreating far faster than others. The welfare crowd, People stuck in a 600AD time warp. Not encouraging.

Women get implants, plastic surgery to make themselves more attractive. Men do tummy tucks, hair implants, eyelids.
Last I checked there wasn't a silicon gene. Their offspring will not look like the altered parents.

Modern medicine keeps weak specimens alive that in turn have children.
Years ago those weak people wouldn't live long enough to procreate.

Are up evolving or devolving. I vote for the latter.

This flies in the face of the notion that genetic bottlenecks have been behind the evolution of mankind. Broadening the gene pool will cause a reversion to the norm. We’re not all that differentiated now, even after presumably tens of thousands of years in isolation from one another.

I do believe in micro-evolution as a Christian. However we will always be 100% human as a species.

From pygmies to giants and from summu wrestlers to jockeys; major differences in stature and size makes to difference; still 100% human.

How the hell do you have evolution without “selection” for attributes that favor success in life.

It is in fact the least-successful people in this world that are propagating at the fastest rate.

Idiocracy is happening folks. Just enjoy society while it lasts.

But eventually, genetic engineering will increase human intelligence.

The very fact that genetic engineering will be designed by flawed human beings belies contradicts notion that genetically engineered humans will be intellectually superior to those naturally evolved by forces we really have no conception.

Also, in the realm of ideas, modern prosperity encourages idiocy. Because there is a cushion for Leftist politicians not to suffer the immediate consequences of their actions, people believe that that drivel is equally valid. When you become too civilized, you loose key aspects of the will and drive that got you to where you are. You start living off the past and are condemned to inevitable decline. One almost has to believe that a the success & advance of modern socieity also contains the seeds of its destruction.

“”Human evolution didn’t stop when anatomically modern humans appeared or when they expanded out of Africa,’’ Harpending said. “It never stopped.’’”

Any claim by these morons that evolution theory is not racist is laughable. The whole thing relies on the less than perfect compared to the more perfected and the destruction of that which is less than perfect.

Crappy-diem.
