think that whole post was good background to the question but I don't think you have yet answered the question as to why biology is unintelligable without evolution
Probably for the same reason that a dictionary is unintelligble unless it's in alphabetical order.

Re: Topic again
There is, IMVHO ("im my VERY humble opinion")a crucial part of evolution that is problematic: the evolution of "mind."
What's problematic about it? Surely you can see the survival/reproductive benefit of having a mind?

Re: Topic again
It's not the evolutionary reason that puzzles me, Crashfrog: it's the process by which mind could have developed.
The process seems completely clear to me, I guess. Given the continuum of mind that we find in nature, from the brightest human minds, to the dumbest human dolts, to the surprising mental faculty of our cousin apes, to the complex behavior from the simple neurology of insects, I see nothing problematic about the gradual development of mind, nor any fundamental quality of the human mind that is not also possessed, to some degree, in other species.
It's honestly not that puzzling to me, and I wonder why it would be to you.

Answer my question in message #40, Crashfrog, and set my mind at ease.
I'm sorry, you don't seem to understand. "What are minds" and "what is the evolutionary origin of mind" aren't the same question. The evolutionary origin of mind seems very simple to me. What, exactly, is a mind? Fuck if I know.

Crshfrog, how could the evolution of mind be simple and unproblematic if we don't know what the hell it is?
We don't know what gravity is, but we're able to calculate it's effects with amazing accuracy.
What something is and where it comes from are two separate questions. But we're getting off topic.

Anyway, as far as I can tell this is a bunch of evolutionists discussing stuff, which is interesting in its own right--sort of like EvE...heh.
Well, that's what science is like. What, you thought scientists just sat around agreeing with each other? Hell no! There's careers to be made!

A lot of funny questions
Who decided that anything needed to survive?
What do you think happened to everything that didn't need to survive?
Do bacteria develop resistance to antibiotics due to copying errors? I don't think they do, but can you see, that even IF they do, it is still a bacteria...even the same general kind of bacteria.
When you say that, what do you mean, exactly? How would you know if it's "still" a bacteria or not?
Did it ever occur to you that the words we apply to certain species are just words, and that they don't describe any kind of inherent specific essence or something that an organism possesses?
What makes a dog a dog? The fact that it is decended from dogs, not some kind of inherent dog-ness. And it might very well become a new kind of organism, one never before seen, yet still remain a dog.
Furthermore, so far as I know, copying errors provide unnecessary duplication of present information, deletion of present information, or mixing-up of present information. Doesn't the development of new life forms require the addition of NEW information?
All those things are new information.
Does duplicated, mixed-up, or deleted versions of old information equal new information?
In a word, yes.
I really fail to see how it does.
Is "appear" a different word than "parapet"? Don't those two words contain different "information"?
Does that cease to be the case when I tell you that those words are anagrams; that is, when I mix up the letters of one, I get the other? If all I have is "appear", and then I duplicate and mix the dupe up and get "appear" and "parapet", don't I have information that I didn't have before?
If they can, how do they do so?
Because the genetic sequences that result are novel, and the proteins they generate may be novel, too.
It's like you're asking "can letters be put together to form words? If they can, how do they do so?" Don't you see what a meaningless question this is?

Evolution doesn't exactly keep assumptions to a minimum...heh.
Well, now, wait a minute. You've consistently criticized evolution for cleaving so closely to materialism and refusing to even entertain the possibility of the supernatural; now you say that evolution makes uncalled-for assumptions?
Which is it? It can't be both ways.

I'm an idiot
It's late and I should be in bed, but I don't think they are anagrams (six vs. seven letters - there's no 't' in "appear").
God dammit.
I'm terrible with anagrams, so I wiki'd "anagrams" and used the first example that appeared. Here's what I saw:
quote:
Anagrams is a anagram board game which is played with tiles from another word game, such as Scrabble or Upwords. At the beginning, all tiles are turned face-down. During the game, players take turns flipping tiles face up on the table.
[edit]
Creating Words
When a player sees a word of four or more letters among the tiles face-up in the middle, this player says the word and puts the tiles for this word in front of him/her. A player cannot create a word which is already on the table.
[edit]
Stealing Words
You can steal a word from another player by mixing all the tiles of one opponent's word with one or more in the middle, forming another word. Mere pluralization is never permitted, however, and sometimes players stipulate that the new word has to change the root of the old one. (example: APPEAR to PARAPET is fine; APPEAR or REAPPEAR is not.)
You can modify your own words, subject to the same rule, to prevent others from stealing them first.
You cannot steal a word by creating a word that is already on the table.
I was quick and careless. Here are some better examples of anagrams:
quote:
Desperation = A rope ends it.
The Morse code = Here come dots.
"To be or not to be: that is the question, whether 'tis nobler in the mind to suffer the slings and arrows of outrageous fortune." = "In one of the Bard's best-thought-of tragedies: our insistent hero, Hamlet, queries on two fronts about how life turns rotten."
and
Anagrams = Ars Magna (latin for "Great Art")
On the other hand, the "appear = parapet" translation may suck as a straight-up anagram, but it's much more like the actual process of mutation, which includes not just changes in the order of base pairs, but the addition of new base pairs as well.

However for reasons I don't quite understand you use terms such as associates professors, assistant professors for various posts.
I've never been to a university in the US where assistant and associate professors didn't have at the bare minimum Masters degrees in their field, or where associate professor was not a tenured position.
We're not just hiring janitors and calling them "assistant professors" around here. Those are ranks, a seniority structure that begins at assistant and rises through full professor, possibly terminating at something like "professor emeritus" or other ranks.
but that the word seems to be so imprecise in the states that the term could mean any number of people in any number of roles.
No, it's pretty much restricted to permanent or semi-permanent faculty engaged in teaching or research, with proper accredation in their fields. In other words it means the same thing as it does in your country.

Just so I can make sure my kids never apply to any institutions that hire people without PhD's into professorial positions, what were these universities?
I don't know that they make the same hiring decisions now as they did in the past; my dad is a full professor and division chair at the University of Minnesota in Morris (regarded as one of the country's finest public liberal arts colleges); he holds no more than master's degrees in (I think) broadcasting, costuming, and technical theatre. He's pretty sure that they wouldn't have hired him today, but when he was hired lo these many years ago, there weren't too many people with Ph.D's in his fields.
I'm sure that at least a few of the professors at Gustavus Adolphus College did not possess doctorates in their field, but I can't think of any full professors offhand.
Given the intense committment and study it takes to even recieve a masters, I don't see this as indiscriminate. While any given field may be flooded with Ph.D's nowadays, this hasn't always been the case in many fields.

Well, I don't know. I'm not exactly an expert on the state of American higher learning, nor the career ladders of American faculty. I'm only familiar with two small liberal arts schools in Minnesota, who typically don't have enough faculty to necessitate the surfeit of hair-splitting titles you describe.
All I know is, there's at least one university in America where a full professor can chair his department with nothing greater than a masters degree, and that that institution is highly rated as a liberal arts institution, and the model of other colleges in the state for a number of programs directly overseen by that professor, and that that professor is my dad.
Take from it what you will.

You still don't seem to be getting what I'm saying - I'm not saying that a british professor is better than an american professor - I'm just saying to someone who works in the british academic system, the american use of the term is too non-specific.
Maybe I'm not communicating effectively here, but I do understand what you're saying, and I'm trying to say that while "professor" may refer to one specific level of faculty in the UK; to my limited knowledge in the US, it applies to only three different levels technically, though perhaps to more people colloquially, in the way that marching band leaders (and soccer coaches, I think?) are traditionally called "professor" or ministers are traditionally called "doctor".
I understand we're not talking about an academic pissing contest (at least, that's not what I'm talking about with you), but rather, the exclusivity of terms.
On the other hand I am having a pissing contest with Percy, which I will probably lose. I am, after all, usually full of shit.

I don't say anything about HOW there came to be resistant or non-resistant varieties of the bacteria, but I do propose that the two varieties pre-exist the introduction of the antibiotic.
If you figured this out all by yourself, then you're to be commended for your percipacity. I do mean that in all seriousness. That's a remarkably insightful realization.
On the other hand if you believe this to be a depature from the "mainstream" evolutionary/biological thinking, then you're misinformed. To my knowledge evolutionists don't propose that environmental pressures stimulate or create certain mutations, but rather, environmental pressures select from pre-existing mutations, exactly as you propose. (Though it is believed that certain kinds of environmental stress in certain organisms can stimulate increased mutation rates in general.)
What I guess I mean to say is that you're so right, we've known this for a while. I'm not sure where you got the idea that mainstream biology believed anything else. I commend you for your percipacity, again.
However, such ideas aren't as effective for supporting the idea that "we can see evolution happening all the time all around us."
Why not? Remember that evolution is mutation and selection; we know that mutation occurs constantly, so any time mutations are being selected for or against by environmental stresses, that's evolution.

Per our earlier discussions, we know the defenses already exist and widespread antibiotic use simply makes the bacteria with these pre-existing defenses widespread.
Right. Which is evolution.
It is only now that I understand that evolutionists may use the term "evolution" to refer to a pre-existing trait being favored as opposed to the development of the trait itself.
Both of those things are evolution, because evolution is simply changing allele frequencies.
But, if the antibiotic is only exterminating the pre-existing, non-resistant variants and favoring the pre-existing, resistant variants, then, when we see resistance develop in a given bacterial population, we are not "seeing evolution occur."
Yes, we literally are. The process you described is called "natural selection", which is one of the two components that change allele frequencies.
This says nothing about HOW the two variants came to be.
We know how they came to be, because we know how bacteria reproduce, and so we know where their alleles have to come from. Thse two variants came from random mutation, which is the other half of evolution.
Random mutation + natural selection = evolution. When we see a hostile environmental factor selection among alleles, and allele frequency changing as a result, we're literally observing evolution.
