Pedal to the metal for human evolution
Mass migrations, the population explosion, and city living fuel rapid rate of genetic change
We can’t see it in our short lifetimes, but human evolution is going faster than ever before. Today, the rate of our evolution is over 100 times faster than it was in the depths of time, according to a paper published in PNAS called “Recent acceleration of human adaptive evolution.”
These statements are misleading since they confuse microevolution with ‘evolution’ itself, in the sense of that which produces Man as Man. And they can lead to passive complacency about the effects of ‘civilization’.

The human genome is changing faster than ever
While it is of tremendous interest to study the genetic compoent of ‘recent’ evolution, the fact remains that human evolution began to go in a different direction in the wake of the Great Explosion (ca. 50000 years ago), especially with the Neolithic/Rise of Civilization. And this is driven by a different form of (macro) evolution visible in the dramatic, and decisive, evidence of the so-called Eonic Effect.

In yesterday’s post,More on Neanderthals/FoxP2 gene I cited the Times article on Neanderthals, here’s the full text:Neanderthals May Have Had Gene for Speech.
There was one point I didn’t discuss:
Dr. Klein said he was disappointed to have lost the genetic support from Dr. Paabo’s work but had not changed his views. “The archaeological record suggests a major change in human behavior 50,000 years ago, and I think there is overwhelming evidence for that.”
But Klein doesn’t need this evidence.
Klein’s important work on the Great Explosion is entangled in wrong genetic explanations, and I think that this misses the point. It seems to me this focus on the FoxP2 gene is misdirected (although important in its context). Klein is looking perhaps for the magic gene to match with his evidence for the Great Explosion period.
Check out history and evolution.com’s The Great Explosion, a short piece connecting with the material in the sections before it on the eonic effect. Whatever the genetic basis for the emergence of modern man we have to be strongly suspicious that the kind of non-genetic evolution seen in the eonic effect is involved in the sudden transformation suspected by students such as Klein.
One problem with the Great Explosion data/hypothesis is that it is assumed that man’s evolution is purely genetic. Perhaps not!!
The eonic effect shows purely abstract system evolution occurring in ca. 10000 years burst of directed evolutionary change, involving all the complex cultural variables falsely ascribed to genetic determinants.
This view is unacceptable to reductionists, but the evidence from the eonic data is unmistakable, and what’s more we have the rationale for the direct comparison of history and earlier evolution.
Time to face the facts, that genetic Darwinism doesn’t foot the bill for a theory of the descent of man. Read the rest of this entry »
