Oh help. The religious orthodoxy that impedes discussion of biological evolution continues with its accustomed dreadful tenacity. Im going to hide in Tierra del Fuego.
One difference between faith and science is that science allows with reasonable grace the questioning of theory. A physicist who doubts, say, the theory of general relativity will be expected to show good cause for his doubt. He wont be dismissed in chorus as delusional and an enemy of truth.
By contrast, he who doubts the divinity of Christ, the prophethood of Mohammed, or the sanctity of natural selection will be savaged. It is the classic emotional reaction of the True Believer to whom dissent is not just wrong but intolerable. Which is unfortunate. If the faithful of evolution spent as much time examining their theory as they do defending it, they might prove to be right, or partly right, or discover all manner of interesting things heretofore unsuspected.
Among the articles of faith: Life evolved from the primeval soup (sheer conjecture; the existence of the soup is inferred from the theory); evolution occurred, as distinct from change; accounting for all characteristics of life (mere assertion); natural selection being the driving force (unestablished). Many of these points are logically separable. Since evolution serves the purposes of a religion, namely to explain human origin and destiny, they are invariably bundled.
A few questions:
It is asserted, though not demonstrated, that point mutations caused by, say, cosmic rays sometimes give an animal a slight advantage over others of its species, and that these advantages accumulate over countless generations and lead to major changes. Demonstrable fact, or plausible conjecture? I note that metaphysical plausibility often substitutes for evidence in matters evolutionary. The approach ignores hard questions, such as whether tiny advantages, if engendered at all, rise above the noise level, or what that level might be.
At any rate, the idea is that slight selective pressure (operational definition, please? Units?) over enough time produces major changes. The idea is appealingly plausible. But, for example:
(1) A fair number of people are deathly allergic to bee stings, going into anaphylactic shock and dying. In any but a protected urban setting, children are virtually certain to be stung many times before reaching puberty. Assured death before reproduction would seem a robust variety of selective pressure.
Yet the allergic havent been eliminated from the population. Why is it that miniscule, unobserved mutations over vast stretches of time can produce major changes, while an extraordinarily powerful, observable selective pressure doesnt? The same reasoning applies to a long list of genetic diseases that kill children before they reach adulthood. (Yes, I too can imagine plausible explanations. Plausibility isnt evidence.)
(2) Homosexuality in males works strongly against reproduction. Why have the genetic traits predisposing to homosexuality not been eliminated long ago?
(3) Pain serves to warn an animal that it is being injured, or to make it favor, say, a wounded leg so that it can heal. Fair enough. But then why did we evolve the nerves that produce the agony of kidney stonesabout which an animal can do absolutely nothing?
(4) There are at least two ways in which a species might change over time. One is the (postulated) accumulation over very long periods of mutations. Maybe.
The other is the concentration of existing traits by selective breeding, which is nothing but deliberate natural selection. The latter is demonstrable, and can happen within a few generations. If a breed of dog has weak hips, for example, the defect can be rectified by interbreeding those with better hips until good hips become the norm. About this there is no doubt. If natural selection occurs as advertised, this is where we would expect to see it.
Now, the genes exist for the brains of a Gauss or Newton, the phenomenal vision of Ted Williams, the physical prowess of Cassius Clay. Presumably (a tricky word) in a pre-civilized world, strong and intelligent people with superbly acute (for humans) senses would be more likely to survive and spread their genes, leading to a race of supermen. Is this what we observe?
Here we come to an interesting question: Do the superior pass along their genes more reliably than the inferior? In primitive tribal societies do we observe that the brighter have more children than the not so bright?
Do the most fit men breed with the most fit women, or with the most sexually attractive? As a matter of daily experience, a man will go every time for the sleek, pretty, and coquettish over the big, strong, bright, and ugly. I mention this to evolutionists and they make intellectual pretzels trying to prove that the attractive and the fit are one and the same. Well, they arent.
(5) If intelligence promotes survival, why did it appear so late? If it doesnt promote survival, why did it appear at all?
(6) People have a wretched sense of small and mediocre hearing. Why? The pat explanation is that people evolved in open territory, where sight is more important than the other senses. People walked erect, keeping their eyes well above the ground so that they could see farther. As noses became smaller, there was less room for the olfactory apparatus.
Is much of this not palpable nonsense? Horses have eves at about the same altitude as people, yet have acute senses of smell. Anywhere but in perfectly open territory, a sense of smell is obviously important in detecting predators, as it is at night, when many things hunt. Excessively small nasal apparatus? Cats and rats have little room for olfactory equipment yet have acute senses of smell. Do sensitive ears take up more space than sorry ones?
(7) Without weapons, humans would appear to be easy prey for almost anything. A persistent forty-pound dog would be a challenge for a single man. A pack of hyenas would have no trouble killing him. Any big cat would need about ten seconds.
People are weak. I once had a semi-domesticated monkey of perhaps thirty pounds jump on me in Bali because it wanted a banana I was eating. I was a husky 180 and lifted weights. I tried to push the thing off of me, and instantly realized I couldnt. The little beast was ferociously strong. I gave it the banana.
A man cannot outrun a toy poodle, cannot climb well (and anyway there arent trees in open territory), cannot swim naturally, has teeth useless as weapons, no claws, and poor musculature. (Why the latter? Strength isnt of value in survival?) He can neither smell nor hear an approaching big cat (say) and, unless armed, couldnt do anything about it anyway. Hiding isnt a choice: People are noisy, their children uncontrollably so. When unwashed, humans reek. Our young are extraordinarily helpless for long years.
Were we already packing heat when we swung down from the trees?
(8) So much of evolution contradicts other parts. Sparrows evolved drab and brown so that predators wont see them. Cockatoos and guacamayas are gaudy as casinos in Las Vegas so they can find each other and mate. But but .
The answers to these questions either lapse into a convoluted search for plausibility or else boil down to the idea that since guacamayas are as they are, their coloration must have adaptive value. That is, it is the duty of the evidence to fit the theory, rather than of the theory to fit the evidence. This is science?
Hard as it may be to believe, nature did not think to consult you about what the most important survival traits are, the speed at which they should be enhanced or eliminated, and the untoward side-effects creatures might be forced to endure to maintain them. What a silly argument. Creatures aren't designed as efficiently as I'd design them, so God must have done it? So God is a distinctly inferior designer compared to you? Heck of a refutation there.
Most balding, sedentary, overweight, city-folk could do the same.
Or, in more general terms, a greater tactile sensory acuity is a good thing, even if you have to put up with an increased pain response to get it.
And, are we still evolving?
So? How about a married one?
Sure. But evolution is tough to see in a timeframe measured in the thousands or hundreds of years.
LOL! Most eloquent summary yet!

Actually, fatal childhood genetic diseases are very rare. Much rarer than fatal genetic diseases that hit you during middle age or later. This is because middle aged people have already had a few children, so the pressure of natural selection is lost on their line.
As for people who are allergic to bee stings, I have never been stung by a bee. Then again, I've never flinched when a bee is around either. Maybe they never bothered me because I never bothered them, but at any rate, it's never happened to me in all my 45 years. I can't believe my case is all that unusual.
Another thing to consider: Recessive traits can carry on deleterious mutations (as well as neutral & beneficial ones) indefinitely in a small percentage of the population. Which is why even severely fatal childhood genetic diseases (progyria, for example) will never be completely eliminated from the gene pool. This is also why homosexuality will never completely disappear, even if every gay person comes out proudly early in life & thus never enters into a sham straight marriage & produces children.
I thought every person with a high school diploma at least knows about recessive traits. How come Fred doesn't? (Maybe he wasn't listening in junior high science class?)
Do I see creationists engaging in "A" above as well? Yes! In equal measure, it seems to me. What irked me about your post is that you insulted myself and others for even reading the article with a grain of salt, rather than offering reasoned arguments against its' premise(s).
Cheers!

The usual evolutionist argument: "I refuse to acknowledge the holes in the theory, so you must be ignorant for pointing them out."
It is my hope that one of these days real intellectuals will come on one of these E vs. C threads and actually discuss this issue without calling each other names.
I guess that lets jennyp, Physicist, and me off the hook, eh?
I just keep reminding myself, "making fun of believers sounds just like whistling past a graveyard".
Something that strikes me: only the creationists can ever hope to know the answer.
It's too bad this guy didn't get a science education. Otherwise he could get on the internet and see "all manner of interesting things heretofore unsuspected."
Actually, schools of psychology/psychiatry have gone away from teaching Freudianism to a large extent over the last few decades. Much of Freudianism has been discredited.
The fossil record is about what it should be in 2004. Do the creationists and IDers really not know this?
I haven't called anybody names. The things this person is confused about are, for the most part, things I would expect someone who is minimally conversant with the topic to be able to answer. To call him ignorant is merely a statement of fact, not an attack.
I myself am ignorant about evolution, although not as completely ignorant as the writer. For that matter, I am also ignorant about physics, although I'm less ignorant than most people.
"Answers" imply questions, which in turn imply reason. Dogma is by definition immune to reason - you either accept it or you don't, but you cannot test it.
