A classic in design in nature:

Chromosomes are densely packed DNA. The two “sister chromatids” of a chromosome, having been accurately duplicated during prophase and secured by centromeres, are arranged with all the other chromosomes on the spindle axis in metaphase. Soon after they are winched apart in anaphase into daughter cells. This elaborate choreography takes place every time a cell divides. The cell cycle is fascinating to anyone who has witnessed it under a light microscope, as you can see here:

Remarkable movies made with super-resolution atomic force microscopy show the parts of cohesin undergoing conformational changes. These hand-over-hand motions operate in the dark without eyes, using ATP for energy. They get it right every time!

Silver Asiatic: I gave you this exact thing before about 6 months ago. You dropped the conversation and did not return. I apologise for that. I need to gain an idea of your understanding. Provide some framework on the question. I just want to know, based on your own understanding of the issues and evidence and data whether or not it's possible for the ID view to be shown to be incorrect. AND is it possible, based on your view and understanding, that the unguided view could be shown to be correct. I don't know why you're finding this so complicated. I'm asking for your own, personal opinion.JVL

Silver Asiatic: I asked you to frame the issue in the hopes that you’re not just asking loaded questions or gotchas. As easy as you think it might be to say if something is possible, would be as easy for you to say how probable it is. But the point is it's not my view or perception of the probabilities; I'm interested in your view of them. If you don’t want to help with probabilities in favor of something “simpler” then, yes, I think that’s a lot trickier. Apology accepted, although I don’t think you did it intentionally. I am interested in your own, personal view. If you don't want to offer it then fair enough.JVL

JVL do you think it’s possible that at some time your ID view might be shown to be incorrect?
Considering that a single cell is much more complex than anything humanity invented then Id view will be shown to be incorrect in the moment a car ,a computer ,etc. will emerge from laws of physics without human/intelligent intervention. Billions of years and no iphone found underground in a coal mining? Why?If there are real chances to appear multiplications of a living cells then a phone than can't multiply itself should have much more chances to emerge.

JVL - if you could assist with the probability measures, that would help. You've made a decision so I'd hope you could - the probability of ... The lucky chance that the universe exists with laws and constants as it is today The lucky chance that the earth emerged with conditions right for life The lucky chance that life emerged from non-living chemicals The lucky chance that cellular life emerged with cell-processing features The lucky chance that single cells multiplied and bonded for complex organisms The lucky chance that human beings evolved The lucky chance that rationality, consciousness and purpose evolved from unintelligent, irrational, blind nature Total those up - and then there's a probability for that. Maybe 1 in 1000 chances? Or one in a hundred billion? or much more than that? When you provide that, someone can say "yes, that's very probable" or not.Silver Asiatic

JVL, in principle possible, I also believe the second law of thermodynamics can be in principle refuted, but for very similar reasons, maximally unlikely. KF PS, that unguided blind chance and mechanical necessity could give rise to life and body plans up to ours is in the same boat as failure of the second law of thermodynamics. And, again, you were already advised on the problems of falsificationism above.kairosfocus

JVL, it was shown in 153 ff above that your redefinition in 150 of "history" and "records" to lend plausibility to the notion that there is observational warrant for claiming that FSCO/I came about by blind chance and/or mechanical necessity fails. You have never cogently answered that. Further to the matter, on OoL, you imply that highly complex code and algorithms [present in D/RNA] -- involving language and goal directed stepwise processes came about by blind forces in Darwin's warm pond or the like, along with the molecular nanotech machinery to effect same, involving metabolic pathways of astonishing complexity and a von Neumann kinematic self replication facility manifesting another order of complex system integration . You and all of us full well know on a world of experience and linked blind needle in haystack search challenge that complex language and goals are highly characteristic of intelligently directed configuration, but you have tried to evade the force by linguistic manipulation. Which, you obviously cannot defend as your switch to tangents shows. It is likely that your reactions and arguments show underlying ideological commitment to the institutionalised orthodoxy of the day, but that is visibly in unacknowledged crisis. Such adherence is not insane and is common but lacks rational support. As for evil, a fair self assessment and evaluation of our common condition will at once show that Solzhenitsyn was quite correct. That is, the line between good and evil first passes through the individual human heart. Further to all of this, evolutionary materialism and so its fellow traveller ideologies too, is manifestly self referential regarding our cognitive powers and incoherently undermines credibility of rational freedom -- e.g. no free will from Provine and Haldane's chemical vs rational soundness -- thus is incoherent and self defeating, self falsifying. It cannot justify its insistence on being a yardstick of scientific truth or knowledge, much less institutional domination. So, instead it would be advisable to address the gaps and revise your thinking to better accord with what we know on trillions of observed cases and search challenge analysis, FSCO/I is a strong, highly reliable sign of intelligently directed configuration as a pivotal causal factor. Fair comment, insistence on a failed paradigm in the face of cogent correction is a mark of ideological commitment, not of sound analysis. Flailing away on distractive, tangential, polarising gambits only further shows lack of weight on the merits. KFkairosfocus

JVL, Instantly, you know, just from the calendar, the date of Christian founding and the founder of the faith defined by the gospel of the realm of God, the realm of truth lived by the right: Jesus of Nazareth, crucified c 30 AD at age 33, and risen with 500 witnesses, about two dozen of whom were prominent enough to be identifiable, especially his chief emissaries of the good news, the apostles. The same circle from which the foundational texts (apart from the Hebrew Scriptures Jesus fulfilled as Messiah, cf Isa 52:13 - 53:12 esp) known as the New Testament came. Islam, coming along 600 years later and asserting that Jesus was not crucified -- as well established a basic fact of history as one gets -- is simply not relevant. So, pretence not to know that Luther coming along 1500 years later as a Christian Theologian based on said scriptures and gospel message, cannot have been foundational, as well you knew all along. As for the sect you seem to suggest as though it were typical, that is what, late C20? And, an isolated sect of low repute by all accounts, for cause. Strawman based distractor no 1 fails. Next, we both know that what was shown in brief above was that the system of thought, evolutionary materialistic scientism, is hopelessly self referentially absurd. In brief, again, we cannot reduce our responsible rational freedom of mind to computation on a wetware substrate without undermining credibility of our reasoning. Haldane highlighted it c 1930 and Provine seemed to fail to see it twenty years ago, without real rational freedom, credibility of mind and its schemes disintegrates. Evolutionary materialism fails. In failing it is unsurprising to see that it has in it no world root is that can properly ground ought, an amorality that opens the door to that gross error of thought, nihilism. Plato knew better 2400 years ago. Finally, your weak turnabout projection also fails. For, as even your own attempts show, it is a regrettably typical pattern of objectors here at UD to use red herrings to go off on tangents: you are already switching from a subject you raised on alleged "history" of the prehistoric past of origins you tried to use to smuggle in the empirically unsupported notion that blind chance and mechanical necessity can and does create FSCO/I. In fact you had begged questions and fallaciously redefined history to lend unwarranted strength to your claims. You proceeded to toxically loaded strawmen and subtly ignited them to cloud, confuse, poison and polarise discussion. [What relevance is the claim of Islam to the fact that neither Luther nor an odd sect could be foundational to the Christian faith, and even that issue is tangential.] Of course, doubtless some ID adherents have behaved poorly and some will doubtless do so again. For, to struggle with evil is part of the human frame. But to try to divert a well founded observation made over more than a decade into a turnabout gambit is a fail. However, such distractions and evasions carry an implicit message: the objections are coming up short on the weight of merits. Otherwise, there would be triumphal, crushing arguments given by those who come here to object, not distractions and evasions. KFkairosfocus

Bornagain77 and Asauber can't quite seem to man-up and accept the fact that they consider anyone who thinks life arose on Earth via unguided processes is insane or evil in some way. But i think they've said as much without being explicit. To me that means their views are unscientific, they do not accept anyway their positions could be shown to be incorrect. This has nothing to do with any evidence I might present, this has to do with their ability to consider their views potentially incorrect. They don't think that is possible. So there is no point in talking about it.JVL

Very telling JVL, you can't be bothered to present any actual real-time empirical evidence for your extraordinary claims,, yet it is the evidence itself that, (if you had any), would stop me dead in my tracks from saying that it is an insane belief to believe that a series of 'selected accidents' can possibly create something as unfathomably complex as the brain or the eye.
The Human Brain Is ‘Beyond Belief’ by Jeffrey P. Tomkins, Ph.D. * – 2017 Excerpt: The human brain,, is an engineering marvel that evokes comments from researchers like “beyond anything they’d imagined, almost to the point of being beyond belief”1 and “a world we had never imagined.”2,,, https://www.icr.org/article/10186 The Human Eye, Like The Human Brain, Is A Wonder https://uncommondescent.com/evolution/from-philip-cunningham-the-human-eye-like-the-human-brain-is-a-wonder/
I don't care if you talk to me or not JVL. I just know, barring any compelling real-time empirical evidence to the contrary, that I am not going to stop saying that unguided Darwinian evolution is a completely absurd, even insane, belief for you JVL, a supposedly sane and rational person, to hold.bornagain77

Bornagain77: I consider your ‘anti-rational’ Darwinian worldview to be completely insane (Haldane, Lewis, Egnor), and I hold that you have, at least, the minimal amount of sanity required to recognize that it is a insane worldview. So, there is no reason you and I should continue to attempt to have any kind of conversation. So I can ignore your comments from no on? JVL, you keep dancing around the fact that you have presented no real-time empirical evidence to support your ‘extraordinary’ claim that unguided processes can create something as complex as the brain. That wasn't the immediate topic. You should try harder to pay attention.JVL
