Why Do People Think Human Evolution Has Stopped?

I can’t count how many times someone has remarked glibly and smugly with glazed eyes and a vacant smile “But we have modern medicine/modern society now.  Human evolution has stopped.”  I’m stunned every time.  I’m used to stupidity, but even otherwise intelligent people will say this to me.  Do they choose not to think?
Do they choose to refuse to understand that nature never takes a holiday and that our genes are locked in eternal competition for survival?  Do they not understand that no one will care about their ‘careers’ past the day they retire?  That our ‘accomplishments’ will be forgotten as soon as we are dead?

Changes in stressors merely change the selectors!  Heavy rains are good for some plants, bad for others.  Socially awkward growing up, I keenly felt the cold steel of Darwin’s axe on my neck every day of my entire youth.  I was trapped in a prison of society’s blazing hostility for over a decade.  I was never allowed to delude myself that everyone succeeds.  Before I was a teenager it seemed I stood on the edge of that ignominious trash pit failed specimens are dumped into by nature’s callous hand.  I’ve never, ever forgot it.

This is, in itself, selection at its best.  Those capable of further reflection will have a major advantage over those that buy into the popular platitudes.

The selective barrier I see in modern affluent societies is for an abstract appreciation of the essentials.

For instance, the type A go-getter that always goes for that promotion but never has any kids, dying out as completely as the dinosaurs, no better than the wino on the street corner, no different than a young man brutally mowed down in battle.
In past generations, the type A’s instincts would have been optimally suited towards breeding with the best mates.

Now, however, a more abstract way of thinking about one’s genetic destiny is required for success…or the total absence of thinking, allowing one to rut without care on the animal level.  These are the two present viable formulae for genetic success in the Modern West.

With humans, we give primacy to ‘environment’ and insist on a ‘blank slate.’
We can breed dogs specifically to herd sheep yet do not believe in breeds of people that have come about from the demands of specialization over the last millennia of civilization?

Childish, williful ignorance at its best.

Those who determine the future of the genes, determine the future of the species.

 

 

An Experiment to Test the “Watchmaker” Objection To Evolution

“The origin of adaptations…is one of the deepest problems in Darwinism.  How do novel adaptations arise from small and gradual beginnings?

There is a genus of finches with mandibles that cross over at the tips…called crossbills… The twisted beak allows the bird to pry open closed (pine) cones.
What Benkman and Lindholm did was to uncross the beaks of these birds by trimming the crossed part of the mandibles with an ordinary nail clippers.
The birds with uncrossed bills turned out to be just as good as ever at extracting seeds from dry, open pinecones.  Byt they could no longer handle closed cones.
Day by day, as the twist in their beaks grew back, the birds did better and better with more and more recalcitrant cones.  After a month, their beaks were completely regrown.
Benkman and Lindholm could measure the value of an adaptation from its very beginnings to its final form.
If crossed mandibles were useful to these birds only when fully formed, then it really would be a puzzle how they could have arisen by natural selection.  The cross would have to appear all at once.
It would be the kind of problem before which Darwin felt his theory would “absolutely break down.”

But the finches began to get better at opening pinecones when the cross in their beaks was still too small to be visible to the eye.  Even a slight crossing of the mandibles confers a small, incremental benefit, making more and more tightly closed cones accessible….
The press of competition in the woods would have made the novelty of a crossed beak more and more desirable, because it would allow its possessor to eat food n one else could eat; the same competitive pressure would favor each new twist…
Today, however, theere is no profit to a sparrow or bunting in a deformed, twisted bill, because the crossbill niche is taken.”

My Commentary: As convincing as these experimental results are, I still wonder about species such as the Emerald Jewel wasp that rely on precision brain surgery on the host of their larvae to successfully reproduce.

What Water Purification and Asian Glow Have In Common

“As population density and travel increased, fermented beverages such as beer became a way to transport a nutritional food stuff as well as a source of safe liquid refreshment. There was an old adage “…the water can kill you but the beer won’t.” People in the West did not realize that boiling water could purify it…

But what about people in Asia?…all drinking water be boiled as a hygienic precaution. One summer day while visiting a distant region of his realm, he and the court stopped to rest. In accordance with his ruling, the servants began to boil water for the court to drink. Dried leaves from the near by bush fell into the boiling water, and a brown liquid resulted…

Thus, two vastly different cultures separated by thousands of miles developed distinctly different ways to deal with polluted water for consumption…

It has been found that approximately half of the Pacific Rim Asian population (Chinese, Japanese, Koreans) possess an atypical alcohol dehydrogenase (ADH) known as ADH2*2 that leads to unusually rapid conversion of ethanol to acetaldehyde … After consuming one or two alcoholic beverages, they may experience symptoms which include dizziness, nausea, headaches, an increased pulse, occasional extreme drowsiness, and occasional skin swelling and itchiness. These unpleasant side effects often prevent further drinking that would lead to further intoxication…

Could it be that a culture rich in an alcohol tradition evolved in the West to deal with the problem of poor potable water quality; while in the East, to deal with the same problem, a culture evolved centered around tea because of the presence of a mutation in a gene?”

Or more likely and way too non-PC for the New York Times, Europeans started out like Asians and evolved a higher tolerance to alcohol. Those who could tolerate alcohol better avoided intestinal parasites and had the vitality to sire more children.

According to the PC narrative of course, human evolution came to a halt a few tens of thousands of years when “modern humans” emerged completely formed and have stayed static ever since.

Also, some have supposed that the burst of productivity that came with the industrial revolution was in part a result of Westerners trading alcohol for tea as the drink of choice.

Intermediary Steps In Evolution That Are Difficult To Explain

Macaws with pretty much no reasoning ability, let alone a scientific method “figured out” at some point in the evolutionary past how to nullify toxic foods by eating a particular type of clay.

Explanation?: Most birds constantly eat grit to enable their crop to grind up food anyway. Did the macaws that just so happened to eat this clay have a survival advantage over others?

Perhaps harder to explain:

A parasitic wasp that must sting its host(a cockroach) in a precise region of its brain in order to get the right results.

There’s no room for error here and successful reproduction is at stake. What might have been the intermediary steps that led to this destination?
