Is Human Evolution Accelerating?

It certainly makes sense in terms of genetic evolution that it would be more likely for there to be accidental mistakes when DNA duplicates. The more people there are, the more copying occurs which results in the likelihood of copying mistakes or mutations. Personally, I think the increase in the momentum of human evolution is becoming monumental but that this is due more to mementic evolution than genetic evolution. I realize that the new science of Mementics has been controversial and encountered many difficulties since its introduction in the 1976 book of Richard Dawkins "The Selfish Gene". Still it makes sense to me that beginning with fully modern humans we have a species whose evolution is governed both by genetic processes and mementic processes which Homo sapiens is uniquely capable of creating. The genetic make up of a diabetic human would put them at an enormous disadvantage in terms of natural selection. With the creation of insulin and other human invention however diabetic are not at the same evolutionary disadvantage that they once were. Now they are more likely to live to produce offspring’s and pass on their genes. The increase of human invention in areas such as medicine and digital technology is accelerating the momentum in human evolution. I speculate that we are on the verge of evolving into an entirely new species

People need to be careful before equating "evolution" and "natural selection" with regards to human evolution. Another extremely powerful selective force, one that often runs counter to natural selection, may be at work: sexual selection. This is the Red Queen theory. If we care to extrapolate, as the authors are certainly doing, then we can just as validly surmise that extinction is nigh.

Is human evolution really accelerating? If so, what does "acceleration" mean in that context? Perhaps it means increasing speed devoid of quality? Consider the number of writers today who can't tell the difference between the word "then" and "than". The original version of this story contained that error twice in one sentence. Now I see someone has deftly avoided a correction by simply removing one of the words altogether, but it's clear they didn't really know what they were correcting, because they left the other identical error alone. (By the way, the original copy of this article -- containing both errors -- is still available from CNN's homepage. Here's the quote: "The rate of evolution is far greater then in the last few millenia, Harpending and his colleagues say, then it had been in the millions of years before.") Why would a magazine dedicated to the high standards of modern-day science allow someone lacking basic writing skills to be a contributor? In my view articles such as this one -- especially given the topic -- are an embarrassment to Popular Science.

The real question is-why are so many people degenerating? What kind of chemicals are contaminating our food and air supplies so thoroughly that our nation has become filled with morons?

Forget the ongoing degradation of literature in this visual age; The logical question is when did this process or increased evolution start and how did the Human gene become altered/infected or was it artificially manipulated to change in comparison to which primative ancestor? Or, are they stating they have confirmation of a specific human thought process that can alter the physical construction of our genes?
