High school biology textbooks would include a disclaimer that evolution is only a theory under a change approved Tuesday by a committee of the state's top school board.
If the disclaimer wins final approval, it would apparently make Louisiana just the second state in the nation with such a provision. The other is Alabama, which is the model for the disclaimer backers want in Louisiana.
Alabama approved its policy six or seven years ago after extensive controversy that included questions over the religious overtones of the issue.
The change approved Tuesday requires Louisiana education officials to check on details for getting publishers to add the disclaimer to biology textbooks.
It won approval in the board's Student and School Standards/ Instruction Committee after a sometimes contentious session.
"I don't believe I evolved from some primate," said Jim Stafford, a board member from Monroe. Stafford said evolution should be offered as a theory, not fact.
Whether the proposal will win approval by the full state Board of Elementary and Secondary Education on Thursday is unclear.
Paul Pastorek of New Orleans, president of the board, said he will oppose the addition.
"I am not prepared to go back to the Dark Ages," Pastorek said.
"I don't think state boards should dictate editorial content of school textbooks," he said. "We shouldn't be involved with that."
Donna Contois of Metairie, chairwoman of the committee that approved the change, said afterward she could not say whether it will win approval by the full board.
The disclaimer under consideration says the theory of evolution "still leaves many unanswered questions about the origin of life.
"Study hard and keep an open mind," it says. "Someday you may contribute to the theories of how living things appeared on earth."
Backers say the addition would be inserted in the front of biology textbooks used by students in grades 9-12, possibly next fall.
The issue surfaced when a committee of the board prepared to approve dozens of textbooks used by both public and nonpublic schools. The list was recommended by a separate panel that reviews textbooks every seven years.
A handful of citizens, one armed with a copy of Charles Darwin's "Origin of the Species," complained that biology textbooks used now are one-sided in promoting evolution uncritically and are riddled with factual errors.
"If we give them all the facts to make up their mind, we have educated them," Darrell White of Baton Rouge said of students. "Otherwise we have indoctrinated them."
Darwin wrote that individuals with certain characteristics enjoy an edge over their peers and life forms developed gradually millions of years ago.
Backers bristled at suggestions that they favor the teaching of creationism, which says that life began about 6,000 years ago in a process described in the Bible's Book of Genesis.
White said he is the father of seven children, including a 10th-grader at a public high school in Baton Rouge.
He said he reviewed 21 science textbooks for use by middle and high school students. White called Darwin's book "racist and sexist" and said students are entitled to know more about controversy that swirls around the theory.
"If nothing else, put a disclaimer in the front of the textbooks," White said.
John Oller Jr., a professor at the University of Louisiana-Lafayette, also criticized the accuracy of science textbooks under review. Oller said he was appearing on behalf of the Louisiana Family Forum, a Christian lobbying group.
Oller said the state should force publishers to offer alternatives, correct mistakes in textbooks and fill in gaps in science teachings. "We are talking about major falsehoods that should be addressed," he said.
Linda Johnson of Plaquemine, a member of the board, said she supports the change. Johnson said the new message of evolution "will encourage students to go after the facts."
when someone advocates a position like evolution, there's an unfortunate tendency to automatically attach to that person a load of unrelated ideas. This is a source of considerable ill will.
I absolutely agree with you, PatrickHenry! Many posts ago you drove home the importance of defining and coming to an understanding of the words we use.
The effort has been very rewarding. Hostile posts are few and far between and that surely helps all of us to listen.
Thank you! Hugs!!!
When Chaitin speaks of randomness he is saying that the string of numbers we are looking at cannot be created by a set of instructions (algorithm) smaller than the numbers themselves. If the string of numbers can arise from an algorithm, it would be algorithmically reducible information.
For instance, if you see a string of 300 numbers that look like "12312312312313123123123123..." you would say that is algorithmically reducible because it can be created in three steps:
In the "airplane parts laying around v. assembled aircraft" illustration, the assembly manual is like an algorithm for building the aircraft.
Although I don't wish to venture whether the aircraft is algorithmically reducible under Chaitin, if we were talking about genetics instead of airplanes, that assembly manual would roughly parallel the subject of evolutionary computing. That is a very interesting subject to me, but not the one that has caused my ears to perk.
If the airplane came alive - was self-organizing and reproducing itself with ever increasing diversity and sometimes, complexity - we would be looking for the algorithm whereby it accomplishes it. That's the part that interests me, because (thanks to Nebullis) I now know that the genetics involved have the characteristics of information theory.
That is to say, it works like a software program, remembering the past (database), being able to decide friend or foe (conditionals/symbols) as well as actually doing the deed (process.) In other words, it can be reduced to algorithm.
Wolfram has shown that complex, seemingly random, structures can arise from very simple algorithms. We are trying to sort out the distinction between complex, random, and structure (and perhaps more before we are done.)
Thanks for your input!
I used the example of a virus and its host to demonstrate that the information content is not a property of DNA sequence alone. In general, DNA sequence is unchanging but it exists in a highly dynamic environment. From my perspective, the environment is analogous to software, while DNA is analogous to hardware.
You are right that the "system" in biology must include the DNA with the environment. There's fixation on the Universal Code (a code that is not absolute, either). But that's one level and not the only crucial one to think about when considering information content of a specific sequence. Just for example, the structure of that sequence determines the interaction of regulatory factors, affecting the "interpretation" of the sequence. DNA structure is independent of the Universal Code.
So, we know about some of the complicating factors. It's not a very straightforward problem to compute the information content of a system in biology.
There, again, I'm not so sure this is easy. We can calculate the channel capacity of a specific state. We know how many errors can kill the interaction between a sequence of DNA and another molecule in a specific environment. Such an interaction is kinetic and the downstream effect of errors are not binary. That is, the "message" doesn't arrive either whole and readable or with too much noise to be read at the destination, but, instead, a reduced message or a message with noise becomes a different, yet readable, message.
Maybe this is all simple for those who love their differential equations, but I don't think it's a simple matter to compute either the information content or the channel capacity of a DNA sequence, per se.
In biology, it's called replication.
In biology, it's called replication.
Indeed, that is one perspective and no doubt the most important for many disciplines - biology, medicine , etc! Notably, these are the more "real world" disciplines.
Im sure that each discipline may have a different way of looking at the same thing and exploring those differences might be at the root of improving our understanding. For instance, it could be that the quandary I am in has to do with the difference between randomness in algorithmic information theory v statistics. Im not sure, but Im confident Doctor Stochastic can help clear it up.
Likewise, you have a different concept of hardware/software than Doctor Stochastics (and mine.) To me, the software (algorithm) is the recording and the hardware is the record player. IOW, the DNA is the recording of the algorithm, the organism is the DNA player.
Others could say the software is the music, the hardware is the record. As PatrickHenry might say, thats a wafer thin difference but an important one nevertheless as we look at information theory and molecular biology.
This gets me every time. Chemistry and, most certainly physical laws, are not indifferent to the sequence chosen.
The determinists are dependent on this fact. You might not be aware, and, apparently, Paul Davies is not aware that the DNA molecule interacts with a whole host of molecules in the environment, using laws of chemistry and physics. It's especially foolish to use this silly canard with respect to an argument about determinism. I'll boil down what his argument amounts to. Life is not dependent on universal laws because a particular reaction is not dependent on specific chemical bonds. He's making a gross generalization error based on anectdotal information.
I might have cut the article too short. Here are the paragraphs that followed the paragraph you quoted through the next excerpt at 4507:
This argument is, however, flawed. The building blocks of life are easy to make because their synthesis is thermodynamically favoured. But stringing them together in an aqueous environment into complex molecular chains like proteins and RNA is thermodynamically uphill. Just as a pile of bricks alone dont make a house, so organic building blocks alone dont make life. Put a stick of dynamite under a pile of bricks, and you dont make a house, you just make a mess. In the same way, merely throwing energy willy-nilly at a collection of amino acids, for example, to drive it against the thermodynamic gradient, wont produce a protein. Just as a house requires the delicate assembly of bricks into an elaborate and specific arrangement, so amino acids need to be carefully linked in a precise way to make a functional protein, rather than gunk. The same goes for nucleic acids.
A hundred years ago, it was commonly supposed that life is some sort of magic matter, and that lifes origin would be analogous to baking a cake. All it needs is the right ingredients mixed in the right order under the right conditions. Today we know that the living cell is less magic matter, more a supercomputer; i.e. it is an information processing and replicating system. The key property that distinguishes life from other forms of complexity is the informational aspect, the message in the genes. Chemistry cannot explain information. Chemistry is the medium of life, but one must not confuse the medium with the message.
I've pointed out that this analogy applies only to some simplistic cases. The picture, in reality, is quite different, as I started explaining, above.
You don't get different music when you play a record on different record players.
There are a lot of ways of looking at biology and evolution. If I had a penny for every model devised, particularly by physicists, I'd be rich. It's advisable to actually learn some biology.
This statement and the whole previous post are nothing but an indirect assault on every non-Christian.
You are trying to turn something which is a discussion of facts into a personal thing. Clearly this is because you cannot discuss the facts. The fact is that you cannot give scientific proof for any of these. The fact is that others holding on to these theories cannot give such proof either. There is more scientific proof against all these materialistic/atheistic theories than there is for them. Nevertheless those who hold to them claim their views are due to their love of science and their following scientific truth not a personal predilection. Now it seems to me that if people holding to these views cannot justify them from a scientific viewpoint but must instead rely on some vague possibility for which there is no scientific evidence, then such people are clearly following some personal predilection not science.
Now the way you can refute the above is by showing that the scientific evidence for your materialistic/atheistic view is greater than for the opposite, not by insults. Let's see if you can meet the challenge.
Nicely said.
:)

That's why I say that the record is like software (algorithm.) There may be differences however when you take the computer analogy, i.e. software can act differently when executed on different hardware.

Agreed! I'm going as fast as I can.
It is always interesting to hear that ideas, in and of themselves, can be evil.
Of course they can be. Are you saying that Nazism was not evil? Are you saying that Communism was not evil? So yes many ideas can indeed be evil.
This is the type of bigoted remark that is typical of Creationists. Lacking the ability to do scientific research, they resort to attacking the motives of people who actually are doing science.
Nope, again trying to make things personal. If you hold that abiogenesis is true for scientific reasons then kindly show how based on scientific evidence abiogenesis is more likely than the intelligent creation of life. To do so, you need to exaplain away the following:
There is a tremendous amount of proof against abiogenesis. First of all is Pasteur's proof that life does not come from inert matter (and this was of course at one time the prediction of materialists). Then came the discovery of DNA and the chemical basis of organisms. This poses a totally insurmountable problem to abiogenesis. The smallest living cells has a DNA string of some one million base pairs long and some 600 genes, even cutting this number by a quarter as the smallest possible living cell would give us a string of some 250,000 base pairs of DNA. It is important to note here that DNA can be arranged in any of the four basic codes equally well, there is no chemical or other necessity to the sequence. The chances of such an arrangement arising are therefore 4^250,000. Now the number of atoms in the universe is said to be about 4^250. I would therefore call 4^250,000 an almost infinitely impossible chance (note that the supposition advanced that perhaps it was RNA that produced the first life has this same problem).
The problem though is even worse than that. Not only do you need two (2) strings of DNA perfectly matched to have life, but you also need a cell so that the DNA code can get the material to sustain that life. It is therefore a chicken and egg problem, you cannot have life without DNA (or RNA if one wants to be generous) but one also has to have the cell itself to provide the nutrients for the sustenance of the first life. Add to this problem that for the first life to have been the progenitor of all life on earth, it necessarily needs to have been pretty much the same as all life now on earth is, otherwise it could not have been the source of the life we know. Given all these considerations, yes, abiogenesis is impossible.
That a plain and simple lie. All that anyone can expect fron new evidence is that it will be consistent with theory. Your continuing assertion that "proof" is expected is a lie. And if you believe in god, it is a sin against God (remember the ten commandments).
No, you are the liar. Darwin himself says in numerous places, and specifically in regards to the Cambrian explosion that the fossils proving gradual descent would be found. Well they have not been found. Evolutionists keep looking for the 'missing link' between man and monkey. They are now back to some ten million years and still no missing link.
That is certainly true. The claim that science has disproved the existence of God is absolute nonsense.
The danger in clinging to stultifying analogies is that it limits your ability to learn about subleties of consequence.
I'm going as fast as I can.
Yes, and I'm impressed with your search for knowledge.
