This paper justifies using trees in studying evolution, but admits the trees are not 'real'. More difficult studying the real bushes?- http://philsci-archive.pitt.edu/9215/1/VelascoFutureSystematics(archive).pdf

Morphology was the first way to look at an evolutionary tree of life. This is comparison by analogy. The better way is homology of DNA, where it is found that patches of DNA that look human are all over the place:-"Darwin claimed that a unique inclusively hierarchical pattern of relationships between all organisms based on their similarities and differences [the Tree of Life (TOL)] was a fact of nature, for which evolution, and in particular a branching process of descent with modification, was the explanation. However, there is no independent evidence that the natural order is an inclusive hierarchy, and incorporation of prokaryotes into the TOL is especially problematic. The only data sets from which we might construct a universal hierarchy including prokaryotes, the sequences of genes, often disagree and can seldom be proven to agree. Hierarchical structure can always be imposed on or extracted from such data sets by algorithms designed to do so, but at its base the universal TOL rests on an unproven assumption about pattern that, given what we know about process, is unlikely to be broadly true. This is not to say that similarities and differences between organisms are not to be accounted for by evolutionary mechanisms, but descent with modification is only one of these mechanisms, and a single tree-like pattern is not the necessary (or expected) result of their collective operation . . . [[Abstract, "Pattern pluralism and the Tree of Life hypothesis," PNAS February 13, 2007 vol. 104 no. 7 2043-2049.]"-My theory is a better fit than most of the popular ones. DNA as a standard code has been around since the beginning of life. Because it has an overlay of epigentic mechanisms, now just being elucidated, it can cause variations on the original themes of types, which then tested by natural selection allows for chosing advanced types. However, epigentics works in large jumps, not the itty-bitty gradualism of Darwin. Epigentics doesn't need itty-bitty in time or form. This fits Gould's punc-inc. It also fits the Cambrian Explosion. And it fits the sudden jump to humans from primates over a 20 million year period. The only thing I believe, but cannot prove, is that evolution was guided to arrive at humans. The above abstract finds DNA humanness everywhere. That fits my theory of guidance and also fits with my belief in God.

DAVID: New DNA studies say evolution goes back and forth in complexity through time, eventually more complex from the more simple, but a tortuous route.:-http://nautil.us/issue/9/time/evolution-youre-drunk-As Simon Conway Morris noted convergence smells of teleology.- I don't know where convergence comes into this research, let alone teleology. Here is the conclusion:-Perhaps the fact that people are stunned whenever organisms become simpler says more about how the human mind organizes the world than about evolutionary processes. People are more comfortable envisioning increasing complexity through time instead of reversals or stasis. Physicist Sean Carroll calls humans " terrible temporal chauvinists" for this reason, because they desperately want the street from the past to the future to run in one direction. The textbook scenarios on early animal evolution might be correct, but they should be treated as hypotheses built by temporal chauvinists. When new data suggests a rearrangement, it must be considered no matter how perplexing the conclusion seems.-Casey Dunn, an evolutionary biologist at Brown University in Providence, R.I. who took part in the still-contentious comb jelly project, now doubts all notions of increasing complexity. Instead, he says the environment selects whatever form handles the challenges at hand, be it simple, complex, or plain ugly. Mother Nature, with her 4 billion years of experience, does not work like Steve Jobs, continuously designing sleeker versions. When asked whether de-evolution, a reversal from the complex to the simple, happens frequently, Dunn replies, sure. "But," he adds, "I wouldn't call that de-evolution, I'd call it evolution." The utter randomness and unpredictability of the evolutionary process described here speaks of anything but an ultimate purpose, other than individual organisms constantly seeking ways of coping with an ever changing environment.-****-Thank you for this and an array of interesting articles.

Why God chose this approach I do not know, but I undrstand your interpretation which comes from not being willing to look at teleology as a possibility.-I think you have misunderstood my objections. You have drawn our attention to an article which explicitly argues that there is no direct line from simplicity to complexity, and that evolution behaves like a drunkard (i.e. it staggers all over the place = my "higgledy-piggledy"). For some reason you interpret this as supporting your thesis (and SCM's) that evolution has a divine purpose, and when I suggest that it does the exact opposite, "all you can do" is quote SCM, whose teleological convergence plays absolutely no part in the article. I have no quarrel with the argument that life (or rather living organisms) tries out many solutions to the challenges of existence. That is the point of the article, which says explicitly that there is no directionality. What the authors describe is only a higgledy-piggledy array of different solutions. Whether living organisms have been "programmed" by your God is, of course, the great issue, but if they have, the utter randomness and unpredictability of the evolutionary process illustrated by the article you have referred us to scarcely supports your anthropocentric interpretation of his purpose. The fact that you cannot find a reasonable explanation for the approach you insist God chose might perhaps be grounds to look for a different purpose! How about evolution as one vast experiment, setting up the mechanisms to see where they would lead? At least that would explain the higgledy-piggledy nature of life's history. You could even surmise that after a few billion years, your God sort of hit on the idea of an organism with an extra degree of consciousness ... a wonderful new dimension for his experiment. At least that hypothesis would get you out of the impossible tasks of explaining 1) how six types of eye, trilobites and dinosaurs were all part of the divine plan to create human beings, and 2) how an article that expressly focuses on a lack of direction provides evidence of direction.

I don't propose to know God's thinking, but what you have suggested may be right on. The point is we have to explain how single celled oganisms complexified through some sort of evolutionary process and ended up as sentient humans which a consciousness that we can describe but cannot explain. If you look at the thousands of examples of convergence in Simon Conway Morris' book it really seems to fit your suggestion. Life keeps adding complexity and seems to go off in every direction at once, but it did arrive at us folks, and that is stong evidence that that end is what was intended. Bacteria are the most successful set of organisms around, lasting 3.5 billion years and with the greatest biomass on Earth. there was no urgent reason for them to attempt complexity, but it was successfully attempted. And this is where I ask the 'why' question, and answer, life had a built-in mechanism to do this as evidenced by convergence. This is SCM's point of view. It is evidence from inference.-By the way, there are other articles coming out now indicating a back and forth in evolutionary history. It appears evolution is a very bumpy road. For example the Permian extinction killed 95% of everything over a sixty thousand year period. And life quickly recovered full blast, but at that point without the poor trilobites who had lasted a quarter billion years from the Cambrian, and we got horseshoe crabs out ot it! Life is tough and won't be killed off, and keeps progressing.-So I reject your opinion. The article does support my point of view and scm's.

Tony: Just to throw a monkey wrench into the debate, what happens if you remove the assumption of speciation from this mix?-Well, how do you get from bacteria to us without it? My position is that evolution did progress from single cell to us but just how it all happened is up for debate. We don't know how speciation occurs and species appear in the fossil record fully developed. Gould pointed this out many years ago. In a way the progression looks almost miraculous as origin of life.

Humor me. Call it a hypothetical situation where we actually look at the evidence and throw away the assumptions which we can not prove(and will never be able to prove).-To me, all that this does is show that complex and simple life have been living side by side for all epochs which we have reliable data for.

You are going to have to define reliable data. I have travelled the Grand Canyon by raft with an internationally recognized expert on Canyon geology. At the time he was head of the geology department at U. Manitoba. I've seen the layers, heard about the aging. I have touched the Great Unconformity. Bacteria have been around for about 3.5 bilion years. There were no humans around at the time of the Vishnu Shist, two billion years ago, which I have also touched. So I don't know where you are taking me. Is your point that the aging techniques are not at all adequate?

My point is we do not have this gradual progression from less complex to more complex. Where complex creatures exist, they exist, with no obvious reliable precursors, and they exist alongside simpler forms already existed and did not grow significantly more complex. At least, we have no definitive evidence that one creature grew into a more complex one, only speculation. I am asking what happens to this train of thought if we remove the speculation about one organism metamorphosing into another organism, something which we have no definitive observations of, and simply look at the evidence for what it actually is instead of what we want it to be? Would our perception about the whole thing change?

We have no definitive evidence for - or observation of - any form of life that does not descend from existing organisms (disregarding the very first living organisms, about whose origin we know nothing and therefore speculate endlessly). The observation that life descends from life is the basis of "common descent", which in turn is the basis of evolution. The alternative to one organism metamorphosing into another organism has to be not just one original form of life but billions. Even if I put on my theist hat, I would find it hard to believe that God would go to all the trouble of specially creating billions of forms the majority of which literally came to a dead end. From our past discussions, I know you would like to restrict your God's creativity to a few "kinds", and your reservations about defining speciation seem to me to be fully justified ... no-one has ever come up with a satisfactory answer ... but if you are prepared to allow Nature to produce its own variations on the original kinds, where do you draw the line? An evolutionist is prepared to allow Nature to produce innovations as well as variations. An atheist evolutionist will no doubt point out that the lack of "definitive evidence" concerning one organism metamorphosing into another scarcely justifies belief in organisms starting all over from scratch (no definitive evidence or observation), let alone belief in an unknown and unknowable divine power producing new organisms out of nothing (no definitive evidence or observation). In the end, everyone has to opt for what seems to them the most likely of all the speculations, or perch on the picket fence. I myself opt for common descent, but remain open as to how the process of evolution originated and how it actually works.

I think the link from David sums up my point nicely, even if on the surface it still holds with the more traditional assumptions of evolution.- "Our work implies that there must be constraints on the range of forms within animal groups, and that these limits are often hit relatively early on...."A key question now is what prevents groups from generating fundamentally new forms later on in their evolution..." -Read more at: http://phys.org/news/2013-07-scientific-evolution.html#jCp-Leaving God out of it for the moment, as I am not trying to get into the debate over whether or not God exists or whether he created anything (I think he did like its said he did, David thinks it did but not the way it's said he did, and DHW refuses to commit other than to say he can't believe what anyone says), but rather I am just trying to get beyond the hype and actually look at the empirical evidence without the additional burden of speculation and dogma. What do we know without adding speculation into the mix? We know these creatures existed. We know that there is variability within a species, and that there appears to be some very hard limitations on that variability. We know that complex and simple life have lived side by side for long epochs of time. -I am just trying to reframe this discussion in terms of what we know instead of what we believe.

Sapiens for 150-200,000 years or slightly more. I still don't see the point you are trying to create. There is no question that most complex and even the simple one-celled species start out fully devloped without gradual precursors. Modifications then are minor and react to environmental pressures, and this is where natural selection plays a role. The article shows this. This is current accepted fact, not belief. It appears Darwin was generally wrong. It also appears that we really do not know how evolution procedes from single cell to complex humans. And most of all we do not know where consciousness came from and how it currently works, but we do know a functional brain is required. Does the brain create consciousness or is it a receiver of some sort?

In terms of what we "know" (disregarding the absolute level on which it might be claimed that we "know" nothing), I would agree with you. Everything else is speculative explanation, for which ... as you pointed out earlier ... there is no "definitive evidence". If "definitive evidence" is to be our decisive criterion, let me be the first to welcome you onto my agnostic fence. But having conceded the limitations of our "knowledge", I eagerly await the next phase of your approach!

One quote here that struck me as particularly interesting was thisaleontologists have paid an enormous price for Darwin's argument. We fancy ourselves as the only true students of life's history, yet to preserve our favored account of evolution by natural selection we view our data as so bad that we almost never see the very process we profess to study . . . The history of most fossil species includes tow [sic] features particularly inconsistent with gradualism: 1. Stasis. Most species exhibit no directional change during their tenure on earth. They appear in the fossil record looking much the same as when they disappear; morphological change I [sic] usually limited and directionless. 2. Sudden appearance. In any local area, a species does not arise gradually by the steady transformation of its ancestors; it appears all at once and 'fully formed.'- That has a strikingly remarkable similarity to the way that civilizations sprung up in various locations all over the earth, 'fully formed'.

dhw: Of course innovations are the key to the evolution of new species, and they would probably not survive if they did not work! This does not mean that new species arrive fully developed without precursors, but that existing organisms change their nature (break free from their constraints), whereas others remain as they were. This is a perfectly conventional view of evolution! Common descent does not preclude jumps (hence punctuated equilibrium, and the proposal that innovations must work at once if they are to survive). It merely tells us that all living organisms descended from earlier living organisms. The fact that we have not discovered the mechanism does not invalidate the theory, or lend tangible support to theism. We have all seen life descending from earlier life. Has anyone seen life that did not descend from earlier life?-DAVID: Please read this current review of the 'gaps' and 'jumps' problem. The conventional view of evolution is that no gradualism is ever found! The assumption that life descends from earlier life is what Tony is questioning. We know we get life only from life. There is gradual complexity as we dig though the layers from older to newer. We may have inferred too much from that appearance.-http://www.uncommondescent.com/intelligent-design/gradualism-the-darwinist-article-of-f...-These quotes are from folks who have accepted Darwin evolution as approaching the truth.-This is a depressing response. We have long, long, long ago agreed that gradualism is out. You have reproduced my post - "Common descent does not preclude jumps (hence punctuated equilibrium, and the proposal that innovations must work at once if they are to survive)" ... and then ignored it. Please stop flogging this dead horse.-Tony also quoted the first article, but missed out the paragraph which says that some groups stay as they are, whereas others innovate. That article does not support separate creation. The new article also debunks gradualism, as well as other aspects of Darwin's theory that we have long, long, long ago agreed are deficient, such as random mutations. If "we get life only from life", the new species can only be the result of innovations from within existing species. Whether this is as a result of inventive interaction among existing communities of intelligent cells in response to environmental changes, or divine intervention (your God dabbling with existing organisms), makes no difference to the keystone of evolutionary theory, which is that all forms of life are descended from earlier forms.

Look at the Cambrian layers, including the new one which is 100,000 years older than the earlier discoveries. Even if you doubt aging techniques, new species appear in an order from ancient single forms to the more complex.

This frightens Dawkins who must have gradual:-"Evolution is very possibly not, in actual fact, always gradual. But it must be gradual when it is being used to explain the coming into existence of complicated, apparently designed objects, like eyes. For if it is not gradual in these cases, it ceases to have any explanatory power at all. Without gradualness in these cases, we are back to miracle, which is simply a synonym for the total absence of explanation." Dawkins, R. (1995) River Out of Eden, Basic Books, New York, p. 83.-And the Cambrian denies:-"Many of the fossils at the new site are better preserved than their quarry counterparts, the researchers report. The new fossils reveal the internal organs of several different arthropods, the most common type of animal in both the new and old Burgess Shale locations. Retinas, corneas, neural tissue, guts and even a possible heart and liver were found." (my bold)-http://www.scientificamerican.com/article/mother-lode-of-fossils-discovered-in-canada/

In an environment where the choice is present, individuals tend to stick to those most similar to themselves, which does not preclude them from mixing if the choice is removed.

This has nothing to do with creationism, though I do not deny it lends credence to it. This is about what we have OBSERVED versus what we SPECULATE about.

This is a partial reply to Tony, but I haven't had time to dig into the sites he has offered me to study. Tony is teaching me. I've raised the issue of subduction zones and this article discusses them in detail with the point I make that layers are compared all over the world to arrive at present theory. The end of the article also throws in some hopeful garbage about origin of life which seems to be obligatory:-http://news.sciencemag.org/earth/2014/02/dawn-plate-tectonics-"The team realized not only do both rocks carry the same geochemical signature, but in comparing the Mariana and the Nuvvuagittuq, they also discovered the rocks and the geochemistry of both sequences change in the exact same way, they report in the current issue of Geology. This finding bolstered the theory that the Nuvvuagittuq sequence is an ancient subduction zone. "Seeing the evolving chemical signature," Turner says, "was much more robust than just saying there is or isn't niobium.'"

I could list study after study after study that demonstrates my point, but you seem rather determined not to see it, which is, ironically, actually my point. Scientist are so hung up on their theories that they can not see the forest for the trees. All of the data staring them in the face that tells them that they are wrong and they ignore it or discard it because it doesn't fit their precious theories. -I think the fact that I am a biblical theist tends to lead to the assumption that every argument I make has to do with creationism or religion. The truth is. This is just bad science. Its no different than the religious fundamentalism of the YEC. Do I think we have the age of the Earth right? No, but it doesn't really make a difference to me either way. It could be a little older, or a lot younger, who knows. The one thing I do know for certain is that the theory of evolution has poisoned the scientific well, and every discipline that has drunk deeply from that well has become sick and twisted, discarding their reason and ethics in favor of dedication to an ideal.

I don't care either tht the age of the Earth is 4.5 or 4.7 years old. I don't think the average scientist is as twisted as you imply. But in theoretical science string theory is swallowing a huge number of careers, and they are fighting tooth and nail to save it and their livelihoods, and that is intellectually dishonest On another tack, you are absolutely correct about theoretical evolutionary theories and Darwinist type scientists. Just like the stringy folks.

There are a couple of different ways that scientist get twisted, and not all of them are intentional. Either:-A) Their entire life they have been told something is true, regardless of evidence, and so they believe it whole-heartedly, regardless of evidence. This in turn shapes their perspective on what they see and choose not to see. -B) The are afraid of being ex-communicated from the academic world, loosing their careers that they have worked hard for. -C) They have invested so much of their life and research into an idea that they are loathe to let it go. -D) They have some sort of personal antagonistic bias against religion (i.e. Dawkins)-A & C to me are the least offensive of the four, and the two that I would consider not necessarily the fault of the individual, per se.

I was in medicine for 41 years, and I gave some to thought to our discussion before you presented this comment. To do the best for my patients I had to accept the basic tenets of the medical science of the pathophysiology of humans. Obviously I developed my own thoughts as I developed experience, that is, I started as A and then modified. This is the reason I approach physcial sciences as I do. I was trained to trust science and understood it could be modified. Science combined with the art of practicing it. -Your analysis of scientists is right on. A's don't learn to think. B's are the Darwinists, and I've actually been approached by a Darwin research doctoral candidate who was hiding his theism, and secretely wanted some references from me! C's are the stringy ones and they are trapped. And D's misuse science because of their agenda.

I hope that gives some context to my arguments here. Science, even evolution, is not particularly contrary to my faith, so I have no reason to be antagonistic to it on those grounds. Rather, I am just tired of seeing bad science. I'm tired of them taking speculation as scientific fact. I'm tired of them ignoring evidence that doesn't fit their theories. I've come across numerous instances where this has happened at the expense of their peers, reaching out and crushing their careers to save their theories.

Perhaps that is why the sciences are populated with so many atheists; no basis in ethical living. And you are describing deliberate incompetent thought. Medicine is somewhat different, at least at the practice level: folks might have a good background of training but can't think their way out of a paper bag. I know of one instance when the professors spotted that in one of the fellows in my internship group. They talked him into going into research instead of practice, and he made a wonderful research scientist. Considering how this country has changed, I doubt that can be done now. I am thinking of the grade creep, every one is marvelous fallacy, no competition environment caused by all the liberals who run establishment education. I suspect that you and I are very similar in our philosophy of life.

Education no long teaches how to think, but rather what to think. So many of the students I have been in classes with over the last few years are what I would consider borderline mentally handicapped (trying to be a little PC here) for their age. Unfortunately, I doubt that many of them even recognize the ethical implications of their actions. The world philosophy at this point is 'fake it til you make it' and 'get everything you can no matter the cost'. -The unfortunate side-effect is that the people moving into the research positions are coming up with that attitude, and it is ruining what should be an objective field.

I'm tired of them ignoring evidence that doesn't fit their theories...-DAVID: You are describing incompetent, immoral people. Perhaps that is why the sciences are populated with so many atheists; no basis in ethical living.-Much as I sympathize with the attack on bad science, this correspondence is now bordering on the fundamentalism you both deplore in people like Dawkins. The claim that atheists have no basis in ethical living is almost libellous. We needn't go into the basis of ethics here (I will later if you want me to), but it will suffice to say that I've never heard of Dawkins exhorting his followers to go out and kill those who do not share his disbelief. I don't think either of you would want all religions to be tarnished by the actions of the fundamentalists, and although unquestionably there are bad scientists who deliberately ignore or suppress evidence that goes against their theories, they are no different from theists who have continued to do the same throughout history. -You have referred to Darwinism in this context. The agnostic Darwin was scrupulously fair in his assessment of the evidence, and agonized over some of his conclusions, but just like Dawkins and yourselves, he was convinced that his theory was right. However, just like Dawkins and yourselves, in order to embrace such convictions he had to brush aside those areas of his belief that were not based on available scientific evidence (and was honest enough to acknowledge it). That is the nature of all beliefs, because science itself is not equipped to cover every aspect of life and its history. At least agnostics do not have to resort to faith, but atheists and theists do, and that means ignoring the gaps in the scientific evidence. -Our hope is always that successive generations will put right the errors of their bad or mistaken predecessors. This is happening now with Darwin, but we can be quite certain that future generations will also find errors in the work of our current scientists, even the best of them. That is how science works and progresses. It is right to attack deliberate falsification, but scientists on both sides of the fence may also have sincere beliefs and disbeliefs that influence their judgement. That is why we have so many books that deal with the same evidence and come to different conclusions. The discussion on the reliability of scientific evidence is genuinely enlightening. I also share the fears David and Tony are expressing about current trends in the academic world, which of course denote a pendulum swing against the equally iniquitous bias when religion held the upper hand. (Tony complains that education no longer "teaches how to think, but rather what to think". Is it or was it ever any different in religious societies?) But the assumption that ethics are the province of the godly is a step too far for me, and it blinds us to the fact that all parties are equally guilty of ignoring evidence that doesn't fit their theories. That, I'm afraid, is common to beliefs in every walk of life.

Religious fundamentalism definitely leads some people to declare their religion is better than any other one, which ib turn has led to wars, bigotry, discrimnination, etc. I wonder how much fundamentalism exists in 'my science is better than your science' as shown in biased peer review. I don't know if it all seems worse now that society is more complex, more interdependent, more politically contrived (global warming) or is really that way.

I won't lay any numbers on that comment, though. I think a lot of the problem comes from institutionalism, whether it is religious, secular, or political. The entire concept of institutionalizing something is to create a 'common framework' or 'common set of beliefs', and there in lies the problem. Once you have a 'common' anything, it is very, very difficult to derail it, and this is particularly true when the object that needs to be derailed is a 'thought' or a pattern of thinking.- **Edit** This is particularly true when that pattern of thinking is supported by heavy investments in terms of time, money, or resources. Just look at how we cling to fossil fuels despite the abundance of 'free' energy.

That, I'm afraid, is common to beliefs in every walk of life.-I apologized for dashing off a reply to Tony that did not reflect my complete thoughts. Lets try again: Tony was describing unscrupulous scientists who were undercuttng rivals. This action has to be understood within the context of knowledge of scientific grants and what that means. Today to survive as an academic research scientist you must obtain grants for supplies, assistents, your salary, etc. To get grants, mainly from the government, you have to produce innovative ideas for research, produce interesting results, and lots of papers about those results. The mosst successful scientists develop a degree of fame. If you don't get a series of grants your career dies. -I have presented here much evidence of fraud in the science literature, problems with peer review, which is just some evidence of the tension involved.-With that background, let me add that over 90% of the American Acadamy of Science members are atheists by self-admission. In the soft sciences like medicine the rate is 60%. -Given the subset of characterists Tony was describing, the odds are overwhelming that 99% of this group are atheists.- On the other hand, I'm absolutely sure that 95% or more of atheists and agnostics are honorable folks. You are right to remonstrate me for a poorly thought out off-hand comment, but it reflects the anger I have, as Tony has also, about the people he was describing.

DAVID: Darwin theory obviously does not tell us how evolution causes speciation, but it must have happened.-TONY: This is the difference between certainty and speculation. You say "it must have happened". I say, show me. While that may seem like an unfair challenge, that is the exact same challenge I am faced with when I express my faith in God. I am told to prove that he exists. In fact, this is the same hang up DHW has with believing in something without evidence of it that is tangible. -For the record, I am NOT saying you are wrong, only that we all must adhere to the same standards. If theist must 'prove' god exists, then evolutionist must 'prove' speciation can, and has, occurred to a degree significant enough to explain the diversity we see today, within the proposed timeline for the history of the earth. I don't care much for double standards.-We are back to epistemology. On an absolute level, we know nothing ... which is tantamount to saying that we do not have "proof" or "definitive evidence" for any of our beliefs. If we did, they would be knowledge (absolute), not beliefs (relative). The most we can hope for is a general, intersubjective consensus among those who are aware of the subject. This reduces our "knowledge" to degrees of consensus. I suspect that you, David and I would agree that the Earth goes round the sun, and is round(ish), so we might refer to these as facts or "knowledge". David and I agree that 1) no-one has ever observed any form of life that did not descend from an earlier form, and 2) there is plenty of scientific evidence that a vast variety of complex animal life came about later than simple, unicellular forms of life; therefore, putting 1) and 2) together, we and many others believe that more complex forms of life evolved from earlier, simpler forms. One must always bear in mind that science is not the only means of acquiring "knowledge", but many of us are loath to disregard science if there is a general consensus among scientists. You are right, though: it's still belief and not knowledge, because there is no definitive evidence. And so we should really preface all our remarks by saying "I believe", or "in my opinion". However, I think even you would find it odd to say each time that in your opinion the Earth is round(ish) (although a Flat-Earther will disagree). Similarly, a scientist like David would not naturally say that in his opinion, diverse forms of life evolved from earlier forms, since he and so many other scientists see it as a "given". On the other hand, he recognizes the lack of general consensus concerning the existence of God, and so it would not seem odd to say that in his opinion God exists. It all depends then on the degree of consensus as to how we phrase our beliefs. "Double standards"? I'd say that is a little unfair. It's an epistemological problem rather than an ethical one.-****-David's response - much more succinct than mine! - centres on "starting point decisions". Once again it comes down to the epistemological level on which you wish to discuss these subjects.

DAVID: I understand your point of view and objections. However the findings described in the article are open to other interpretations if you let the "whiff of teleology" enter your thinking. -I'm afraid that is like saying that the authors' description of a higgledy-piggledy lack of direction can also be interpreted as planned directionality if you allow yourself to think of it as planned directionality.-dhw: How about evolution as one vast experiment, setting up the mechanisms to see where they would lead? At least that would explain the higgledy-piggledy nature of life's history. You could even surmise that after a few billion years, your God sort of hit on the idea of an organism with an extra degree of consciousness ... a wonderful new dimension for his experiment. DAVID: If you look at the thousands of examples of convergence in Simon Conway Morris' book it really seems to fit your suggestion.-Thank you.-DAVID: Life keeps adding complexity and seems to go off in every direction at once, but it did arrive at us folks, and that is stong evidence that that end is what was intended.-It is evidence of nothing at all except the fact that evolution arrived at us folks. It also arrived at millions of other species, and has presumably not yet finished its course. DAVID: Bacteria are the most successful set of organisms around, lasting 3.5 billion years and with the greatest biomass on Earth. there was no urgent reason for them to attempt complexity, but it was successfully attempted. And this is where I ask the 'why' question, and answer, life had a built-in mechanism to do this as evidenced by convergence. This is SCM's point of view. It is evidence from inference.-For evolutionists there clearly has to be a mechanism that caused single celled life to evolve into multicellularity and eventually into us. That was the basis of our whole discussion on "the intelligent cell", which whether invented by God or not explains both convergence and higgledy-piggledy. Convergence (e.g. your six different types of eye) describes the versatility of the mechanism but, if anything, argues against your specific purpose. (Why six types, when humans only need one?)-DAVID: Life is tough and won't be killed off, and keeps progressing. So I reject your opinion. The article does support my point of view and scm's.-No-one would deny that life is tough and won't be killed off (although the article emphasizes that it appears to regress and to progress higgledy-piggledy). That is the whole basis of the evolutionary theory: organisms adapt and innovate in order to cope with their environment. However, I still can't find any passages in the article that support your anthropocentric teleology.
