Modulous writes: How many mutations are beneficial is determined by how 'fit' the population is to its environment. The more specially adapted it is, the easier it is for small perturbations to disrupt the adaptation. An example: Humans are built under the assumption that we'll have four limbs. It is possible to live with fewer, but even with communal assistance, the survival/birth rate is likely inhibited in the very long term. Trying to add more limbs is even worse. Our physiology is 'fine tuned' by evolution {or God if you insist} so any mutation that results in extra limbs is likely to cause problems elsewhere even if they are improbably useful limbs. Blood flow management, the nervous system, balance and so on are all likely to be impaired by the new structures. Historical constraints are an interesting part of evolution. One of the features of evolution is that it tinkers with what is already there. What you don't see in a lineage of species is evolution stripping morphology down to the basics and then rebuilding it. A good analogy is a building. When you start, it is relatively easy to change the foundation of the building to whatever you want. However, once you start building on top of the foundation you can't change the foundation anymore. Morphology is a lot like that. Things like 4 limbs formed the foundation of the tetrapod body plan. Even to this day we still have the same bone structures as the transitional tetrapods, such as Tiktaalik. For example, the forelimb of tetrapods, starting from the shoulder, have one bone, two bones, bunch of little bones, and phalanges. Everything from alligators, bats, and dolphins have this arrangement.

Both evolutionists and creationists agree that most mutations are neutral, some are harmful, and only a very small proportion are beneficial.
Actually we probably underestimate the number of harmful mutations if we don't count those that result in early miscarriage; and I understand there are a lot of these in humans. However even the very few beneficial mutations are usually information losing in some way.Adult lactose tolerance is a defect in regulation of lactase which should cease after weaning. Sickle cell trait is a defect in red blood cells that has an incidental benefit in resisting malaria. For evolution; microbes → man; to work requires addition of large amounts of genetic information. Of course devolution; man → microbes; will work with loss of genetic information. Moving microbes to man requires thousands of new proteins. A major problem is that functional proteins appear to be exceedingly rare in the space of all proteins. Axe estimated it to be about 1/10^77. This makes de novo production of new proteins practically impossible. Even minor changes in existing are unlikely if more than a few non beneficial steps separate beneficial ones. Evolutionists usually appeal to large numbers of organisms and deep time to overcome these probabilistic barriers but the Denton has estimated that only 10^40 proteins could have existed in all of earth's history and this is simply not enough to make the evolution story plausible. You are unlikely to find fossil remains that show clear deleterious mutations. First because many are lethal in the embryonic stage and then many more will be eliminated early in life. In any case we would expect clearly deleterious mutations to be a minority in a population and hence unlikely to be in the small proportion fossilised.

However even the very few beneficial mutations are usually information losing in some way. ... Please define how "information" in this context is defined and then show us how it is quantified and measured. You must have this already if you are claiming it is being lost, or you are making stuff up. Next, are you sure "information" is relevant to whether or not evolution occurs? See Irreducible Complexity, Information Loss and Barry Hall's experiments, another post of mine from 2004:

A major problem is that functional proteins appear to be exceedingly rare in the space of all proteins. Axe estimated it to be about 1/10^77. This makes de novo production of new proteins practically impossible. I don't think those stats are correct for what you're trying to say. There's chemistry involved, so it's not going to be the same as like the odds of a purely-physical event happening, like coin flips or something. Like if there were electromagnetic forces involved in the coin flip, it might not be purely random anymore; the chemistry catalyzes certain reactions and not others, plus, the "space of all proteins" would include ones that aren't even realistic. But to go with the coin flip analogy, you're saying something like: There are two ways in which a coin can land on its side, heads or tails. But, there are a almost an infinite number of ways that the coin could land one of the many places along its edge. Therefore, it is practically impossible for a coin flip to land on heads or tails.

However even the very few beneficial mutations are usually information losing in some way. Really? How do you measure genetic information? Please provide the units of measurement. Without units of measurement there's no way of telling whether information is lost or gained. Edited by Pressie, : No reason given.

The idea of "information losing" is pretty silly. You don't get useful information without picking and choosing from the available data.

@RAZD, @Pressie, @ Dr Adequate
How is information defined, quantified, measured, and what are the units of measurement? You are suggesting that without these data information can't be said to be gained or lost. Is there such a thing as beauty? Can one woman be more beautiful than another? But how is beauty defined, quantified, measured, and what are the units of measurement? I have a copy of Origin of Species. Do I have information on the subject of evolution? If I buy a copy of Why Evolution is True do I have more information? (You could possibly argue I now have less information.) Claude Shannon did find a way of measuring information but he acknowledged that this did not include any consideration of meaning. The normal use of information, and the way I have used it, implies meaning so Shannon Information is not a measure of information. (But it was relevant for the purpose Shannon was using it for.) A dictionary and a recipe book could have the same number of words and the same Shannon Information but if I want to bake a cake one is more useful to me than the other. That is specified information. So we don't have to precisely define, quantify, and measure information for it to be real and for us to talk comparatively about gain or loss of information. E Coli has a genome of ~5e6 base pairs and ~5000 genes. Humans have a genome of ~3e9 base pairs and ~20,000 genes. There is little doubt that the human genome contains more information than the E. coli genome. So I can say that For evolution; microbes → man; to work requires addition of large amounts of genetic information. Of course devolution; man → microbes; will work with loss of genetic information. without being able to actually define, quantify, or measure with units the precise amount of information.

Just out of interest really, do you think that a bi-plane (two winged aircraft) contains more 'information' than the more evolved mono wing?

CRR writes: What a long, long way of acknowledging that you don't have the foggiest of what you're talking about when talking about "more or less genetic information".
@RAZD, @Pressie, @ Dr AdequateHow is information defined, quantified, measured, and what are the units of measurement? You are suggesting... CRR writes: So, let's get it clear. You measure 'genetic information' as the number of base pairs in the genome together with the number of genes? Is that how you do it? So we don't have to precisely define, quantify, and measure information for it to be real and for us to talk comparatively about gain or loss of information. E Coli has a genome of ~5e6 base pairs and ~5000 genes. Humans have a genome of ~3e9 base pairs and ~20,000 genes. There is little doubt that the human genome contains more information than the E. coli genome. So, according to you the bigger the number of base pairs together with the bigger the number of genes the 'more the genetic information' an organism has? Is that how you quantify "genetic information"?

Amoeba dubia has a genome 190 times the size of the human genome. Genome size is not a measure of information.

You are suggesting that without these data information can't be said to be gained or lost. What we are saying is that if it cannot be quantified you cannot state with authority that it is always lost through evolution.
Is there such a thing as beauty? Can one woman be more beautiful than another? But how is beauty defined, quantified, measured, and what are the units of measurement? So you're saying that "information" in your view is subjective, one person thinks "A" is more beautiful while another person thinks "B" is more beautiful? Are you saying that information is in the eye of the beholder? If so, then loss of information through mutation is your subjective opinion, not mine, not fact.
I have a copy of Origin of Species. Do I have information on the subject of evolution? If I buy a copy of Why Evolution is True do I have more information? (You could possibly argue I now have less information.) Are you saying that the information in organisms is printed on pages inside the organism? Or are you conflating one definition of information with another -- the logical fallacy of equivocation?
Claude Shannon did find a way of measuring information but he acknowledged that this did not include any consideration of meaning. The normal use of information, and the way I have used it, implies meaning so Shannon Information is not a measure of information. (But it was relevant for the purpose Shannon was using it for.) So you agree that Shannon information shows a method that quantifies information but that this does not apply to organisms and evolution. Fascinating. At least you know what a metric is that can be used to measure something.
A dictionary and a recipe book could have the same number of words and the same Shannon Information but if I want to bake a cake one is more useful to me than the other. That is specified information. And now we get to one of the latest IDolgist pet phrases designed to appear meaningful while signifying nothing of the sort. I refer you to the argument in Message 34 and I will now insert the word "specified" into the argument to demonstrate that it is meaningless as well:
Next, are you sure "specified information" is relevant to whether or not evolution occurs? See Irreducible Complexity, Information Loss and Barry Hall's experiments, another post of mine from 2004:
quote: If you are wondering why I keep referring you to 13 year old posts of mine, it is because that is when I made these arguments and they have not been refuted since. You are welcome to try, but you should know what you are up against. Curiously I believe that the concept of "specified information" was devised since 2004 to attempt to get around the fact that "information" was not quantified. This is typical of creationist and IDologist dodge, moving the goalposts (deflection) to avoid admitting they are wrong and do not have a quantifiable metric that can actually measure the amount of information before and after evolution has occurred. As you can plainly see, however, the concept of specified information is just as irrelevant to evolution as was the concept of information as it was previously used.
So we don't have to precisely define, quantify, and measure information for it to be real and for us to talk comparatively about gain or loss of information. E Coli has a genome of ~5e6 base pairs and ~5000 genes. Humans have a genome of ~3e9 base pairs and ~20,000 genes. There is little doubt that the human genome contains more information than the E. coli genome. Why? As noted by others there are many organisms with much longer DNA, involving many more base pairs, especially single cell organisms -- do they have more "specified" information? That raises a LOT of doubt to my mind about what you really mean by information, and that without such meaning, comparing one organism to another on this basis is meaningless. ABE: AND, of course, if you DO insist on genome size being a measure of the information about the organism, it is a simple matter to show that DNA insert mutations add to the genome. /ABE
So I can say that For evolution; microbes → man; to work requires addition of large amounts of genetic information. Of course devolution; man → microbes; will work with loss of genetic information. without being able to actually define, quantify, or measure with units the precise amount of information. And you can say it till you are blue in the face, and that won't alter the fact that you are wrong because your use of information is meaningless to evolution. You're just making it up.
... microbes → man ... Let me correct that for you:
... first microbes → all other life on earth since the first microbes, including but not limited to all the other microbes ... All done without information being relevant.
... Of course devolution; man → microbes; will work with loss of genetic information. ... Are you saying that all (any?) current microbes (or any other types of organisms) have evolved from humans?

This is typical of creationist and IDologist dodge... The whole idea of information loss is a necessary part of creationist dogma. This stems from belief in "The Fall" and sin since the Garden of Eden, which represented a state of perfection. All the efforts we see related to information loss are simply attempts to make reality conform to creationist belief. Reality is quite stubborn though, and doesn't change in spite of what one group or another happens to believe.Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge. Belief gets in the way of learning--Robert A. Heinlein In the name of diversity, college student demands to be kept in ignorance of the culture that made diversity a value--StultisTheFool It's not what we don't know that hurts, it's what we know that ain't so--Will Rogers If I am entitled to something, someone else is obliged to pay--Jerry Pournelle If a religion's teachings are true, then it should have nothing to fear from science...--dwise1 "Multiculturalism" demands that the US be tolerant of everything except its own past, culture, traditions, and identity.

You are suggesting that without these data information can't be said to be gained or lost. Is there such a thing as beauty? Can one woman be more beautiful than another? But how is beauty defined, quantified, measured, and what are the units of measurement? Are you trying to suggest that the amount of information in a genome is a mere subjective opinion like which of two women is prettier? Then what use do you wish to make of the concept in a discussion of science? When you say that "mutations are usually information losing", how would that be different from me saying "Eyeshadow usually makes women less attractive"? If the information in a genome is not an objective fact about it, but a subjective feeling you have about it, then what relevance does it have for science? Suppose I were to reply that I personally feel that most mutations increase information, what then? Wouldn't we just have to say "ah well, tastes differ"?
So we don't have to precisely define, quantify, and measure information for it to be real and for us to talk comparatively about gain or loss of information. E Coli has a genome of ~5e6 base pairs and ~5000 genes. Humans have a genome of ~3e9 base pairs and ~20,000 genes. There is little doubt that the human genome contains more information than the E. coli genome. So, would you like the size of the genome to be the measure of the amount of information in it? That would be fine by me, the standard creationist blather about information is false given any coherent definition of it. Edited by Dr Adequate, : No reason given.
