quote: No, Fred, I didn't. I pointed out that information that "never existed before" could appear in a genome, since you got so tetchy about what constituted a new algorithm & an altered algorithm. I also pointed out that evolution required new information, or since we got into semantic word games about what "new" entailed, information that "never existed before" would amount to the same thing. You said this is impossible, I showed it was possible. A quick summary of our previous conversation. You claim that new information in the genome is impossible. You define new information as the presence of a new algorithm (coding sequence) in the genome that codes for a new useful feature. I cited the flavobacterium that gained nylon digestion function by the addition of a thymine in the nyl c gene. This meant that the algorithm was new, the feature & function was new, & that therefore, your definition of new information had been met. You started getting semantic about what was meant by new, by claiming that the genetic algorithm was altered, not new. I point out that you have retreated from any meaningful rebuttal of evolution from an informational pov, because the things you say can’t happen, like leg to wings, can happen without new information, it just requires information that never existed before. Or altered algorithms, right? There is effectively no limit to what an altered algorithm can effect. You can alter algorithms in chimps & get humans, for example. So, either; 1/ New functions don’t require new information, just altered algorithms. Meaning new information as you define it isn’t a barrier for evolution anyway, because evolution only claims to have altered algorithms. Regardless, IT IS STILL INFORMATION THAT NEVER PREVIOUSLY EXISTED. 2/ You are playing semantic games by claiming the nyl c gene is only an altered algorithm. Either way..

Fred,
quote: Firstly, I HAVE given an example of information loss, read the thread. Secondly, you patently DID NOT respond to; http://EvC Forum: Information and Genetics -->EvC Forum: Information and Genetics It came AFTER your alleged response. Please point out where the points made here were responded to before I made them??????? I reiterate (but it would be helpful if you reread the entire post & arguments leading to it);
quote: With reference to posts 107 & 112 in this thread, please. I want to know why "new information" is the "dagger in the heart" of evolution, but "information that never previously existed" from generation to generation, isn't? Or am I making a strawman, here? Please read all the relevant threads, you're not the only one that doesn't like repeating themselves. Mark ------------------Occam's razor is not for shaving with.

Quetzal,
Fred may not have defined "information", but he HAS defined "new information" as it pertains to the genome.

Fred,
You've been responding to a lot of posts recently, & I know you don't have much time, & it would be easy to skip over relevant portions of peoples posts, which is what I think you have done here. Perhaps it would be easier if I remade my case bit by bit. For the record. You claim that information theory doesn't allow evolution to occur because NEW information cannot arise. I take an opposite view. So.... Do you accept that the nyl c thymine addition in flavobacterium allowing nylon "digestion", represents information that didn't exist in the previous generation (that never had the extra thymine)? If not, why? Remembering that you define new information (for genomic purposes, at least) as "the presence of a new algorithm (coding sequence) in the genome that codes for a new useful feature. The algorithm that codes for the nylon digestion is different, & didn't exist in the previous generation, so it makes perfect sense that this gene represents information that didn't previously exist, AND it represents a "new useful feature".

quote: quote: Fred, this is what happens when you bail out half way through discussions. I have explained the following 945,658 times ; YOU are claiming that new info is IMPOSSIBLE, therefore, because evolution needs new info, evolution is impossible. A thymine addition (to the carbohydrate gene in flavobact) is POSSIBLE. This nucleotide addition changes the function of the gene. Ergo, a gain in function of nylon digestion IS POSSIBLE. I really don’t care whether it happened that way, or not, BUT INFORMATION THAT WASN’T PRESENT IN ONE GENERATION [I][b]CAN[/I][/b] BE PRESENT IN THE NEXT. OK?
quote: Agreed, but, if the original gene is conserved (duplication), then there is no net info loss for the organism, it has two genes, with different algorithms that perform different functions. Therefore, there has been a net gain in information. Remember, you are saying it is impossible, before you go off on one regarding gene duplication, I am just presenting a scenario that is possible. Hence, we have a possible mutation(s) that CAN result in information gain (or information-that-never-previously-existed, if we are going to dispute the newness of algorithms).
quote: quote: Irrelevant. If it represents a new useful function (by your definition) to the bacteria in the pool of nylon, then it is information to them, but not to bacteria who aren’t in contact with nylon. It’s a bit like writing a letter to 10 people in Mandarin Chinese, if only one of them reads Chinese, then the letter only represents information to one person, it’s not an all or nothing proposition. So, in summary; A thymine addition combined with a gene duplication can represent net info gain, since a new useful function has been gained without loss of the original function. You are saying this is impossible, the above scenario is possible. Put in terms of your definition of new information, a new algorithm/algorithm-that-never-previously-existed that codes for a new useful feature, without loss of the original feature is possible. Hence, whatever way you slice it, information has been gained. Mark PS We are not beating a dead Cheetah, we have only just reached the point where we left off! PPS I also note that you didn't answer the question at the top of this post, but seemed more concerned with whether it represented net gain, or not. Forget about net gain, just consider the "information that didn't exist in the previous generation" part. ------------------Occam's razor is not for shaving with.
