Dcscccc, wonderful! Glad you are going to stick with scientific evidence from now on! BTW, it was you, my friend, who who brought-up theology in using âthe creation modelâ as the authority for your claims, where you said earlier:
ââŚyour best evidence for evolution its easily explain by the creation model without any need for evolutionâ
It doesnât get much more theological than that, albeit misguided theology, as we, including many noted Bible scholars, are now convinced. Since you first brought it upâŚalso, BTW, is your creation model the minority YEC model or a predominant old-earth creation (OEC) model? I know it wasnât a minority EC creation model. Or Iâll assume it is the âcreation modelâ Ken Ham referred to in his debate with Bill Nye. Theology is the crux of the matter in our discussions.
Iâm being facetious about your promise to stick to the scientific evidence, of course, because the only thing youâve established is that you have no intention of fully engaging with the evidence, other than to take pot-shots at it. If you really were engaging with it you could easily find these answers yourself with little trouble.
Please donât take that personally. Iâm sure youâre a wonderful person just trying to be faithful to our Intelligent Designer.
I get it. Believe me, I got it for 35 years. The gospel of Jesus makes so much sense of life that, if youâre convinced that evolution = atheism, evolution becomes UNTHINKABLE. And, of course, having outspoken media atheists, like Dawkins, capitalize on the FALSE âcreation or evolutionâ dichotomy only make you dig in your heels further. But, by buying-into that FALSE dichotomy of polar extremes, you make yourself the TOOL of the new atheists. They love to have Christians argue this way because it destroys the credibility of our witness for the gospel of Jesus. Even a 5th grader knows they are right about the evidence (just NOT their scientism and metaphysical conclusions about God).
I and other EC view folks are convinced that there are far better perspectives in the EC view if Christians would only engage with that instead making ad hoc anti-science barbs and lame arguments against modern science conclusions that have destroyed the credibility of our witness in the eyes of educated people. And the gospel of Jesus still makes the same sense of life.
If Biblical revelation was about revealing science in the Bible, rather than simply accommodating to an ancient understanding of such things, donât you think God would have explained that the moon goes around the sun and reflects the sunâs light instead of calling the moon one of the âtwo great lightsâ in Genesis 1:16? Bill Nye was booâd by Christians for saying that the moon reflects the sunâs light because God supposedly called the moon a âgreat lightâ, much to the delight of the atheists. Then again, why would God go into all that?
Or do you believe in the solid dome (firmament) that held back the Heavenly sea from the waters below? Thatâs what the Bible literally describes and what ancient Near East ANE evidence shows people back then believed, as well as Augustine, Luther, and Calvin. Whaaat? I know, crazy right? See what they really said about the firmament here in, Is Scientific Concordism Really a Feature of the Bible? taken from Lamoureuxâs college course with permission.
For example, St. Augustine in the âLiteral Meaning of Genesisâ, 415 AD, said:
âThey must certainly bear in mind that the term âfirmamentâ does not compel us to imagine a stationary heaven: we may understand this name as give to indicate not that it is motionless but that it is solid and that it constitutes a impassible boundary between the waters above and the waters below.â
The emphasis was in the original, BTW.
The YEC response that I actually heard just the other day directly from someone who is a Tour Guide at Hamâs Creation and Earth History Museum is that solid dome really was created there but it went away when the windows of Heaven opened up during Noahâs flood. If it supposedly went away, then why is the same Hebrew word for firmament still used in the Psalms, Ezekiel and the book of Daniel?
Honestly, why would God do anything but accommodate to their ancient science. It would have distracted and confused them from the main message that the sun and moon are not godâsâthat there is one God who created us, etc. HOW it happened is incidental to the WHY it happened and what it means to our relationship to God spiritual message. So, we separate and donât conflate the INCIDENTAL ancient âscienceâ from the revealed message, as Lamoureux teaches so well.
Lamoureux was a committed publishing YEC left his career as a doctor of dental surgery (DDS) to get a PhD in Biology on tooth evolution specifically to prove evolution wrong. It was proved right to him in the process. Then he went on to get an M.S. and PhD in theology.
Also note that your model does absolutely nothing to explain the HOW of Godâs essential design was accomplished. Did that design happen in an instant, a minute, a 24h day or through an epoch of time? You canât even begin to answer those questions without an alternative mechanism, which you have not proposed.
An evolutionary creation (EC) model, on the other hand, explains how Godâs essential design could have been accomplished via evolutionary processes that were part of the nature God creation and that explains how âendless forms most beautifulâ have come into being. While it wasnât obvious to me as a typical creationist, one way that could have happened is in, âWhat if Evolution Mean High Intelligence and an Advance Civilization Were Inevitable?â.
Your creation model, on the other hand, argues against modern science conclusions and is, thus, an anti-science model.
Maybe you donât know that churches âcoming across as anti-scienceâ is the #3 reason youth leave the church today? See the 2011 Barna Group study and my about section for more cited stats, such as 45% of 18-22 year-olds leave Protestant churches, never to return.
The old Functional ERV Argument
Iâve heard youâre âfunctionalâ argument for years and it is not the least bit persuasive. I am glad you raised the typical creationist argument that [some] ERVs are functional as evidence for design. I was going to bring that up in my last post, but it was getting long and, well, I knew that would be your next argument.
Iâm sure by âfunctionalâ or not âneutralâ you donât mean a functional provirus but that the sequences from ERVs are involved in some functional role in the host genome, e.g., like synthesizing a sticky protein that mammals co-opted or exapted to evolve a placenta or being located in the genome in a position that affects gene regulation of some other gene product in a function-altering way.
Before I focus on the science, let me also point out that I agree with you that functionality (along with beauty and complexity) are ultimately pointers to a purposeful Designer of the universe. I take by faith that God created all of nature. I believe in an Intelligent Designer, just not ID theory. The nuances of that are described by Lamoureux here.
Your âFunctional ERVâ argument is not persuasive for at least the following reasons:
(1) No alternative mechanism has been proposed for how they were otherwise designed to be functional, i.e., other than through an evolutionary mechanism that can be explained.
Only an evolutionary model exists to explain the ERV data on the whole. To falsify, youâd need a substantiated working creationist model that is consistent with uncommon ancestry and incorporates the whole of ERV data. Iâll not respond to continued ad hoc arguments without such positive evidence.
(2) Functionality of some is exactly what weâd expect via an evolutionary mechanism out of hundreds of thousands of infections in our genome. Other HERV/ERV cause or predispose us to disease. Others are neutral.
In addition to deletions, point mutations, other insertions, and etc., HERV/ERV infections, as well as SINE and LINE transposable elements, are another source of genetic variation (the fuel of evolution, if you will) upon which natural selection (the driver) can act. This allows species to adapt over time to changing environments.
Evangelicals, and even YECs, DONâT have a problem with adaptation through mutation and natural selection. But, speciation, or what typical creationist call âmacroevolutionâ (where they draw the lineâor used to???) can then occur whenever enough mutations have accumulated within members of a species that have been geographically (or otherwise) separated for a long time, e.g., 150 thousand years, such that they can no longer mate and reproduce progeny that can, in turn, reproduce.
Even Ken Hamâs young-earth creationistâs (YEC) org, Answers-in-Genesis (AIG), doing a 180 on evolution, now saying millions of species âevolvedâ from just a few in 4,000 or so years since the Genesis flood. Whatâs up with that? Thatâs hyper-evolution or evolution-on-steroids. Ken Ham is more pro-evolution as Godâs creative tool than ID-Theory people. Really!?! That was my, âBig Surprise in Ken Ham vs Bill Nye Debate".
There is strong selective pressure for those infections that do produce a functionally beneficial effect. Those infections that produce a useful function are the most likely to favor survival and successful reproduction. But, youâd expect other infections to produce deleterious effects (e.g., predisposition to disease), but yet remain if they did not threaten life or the ability to find a mate and reproduce. Over time, youâd expect those producing deleterious results to simply be inactivated by point mutations or other mutations, resulting in a healthier organism that would be selected for preferentially. Those would then be neutralized (i.e., neutral), as we have every reason to expect that the overwhelming majority of ERVs are. Itâs not hard to understand.
And what we expect is what we find. Some have functional co-opted by the host, either affecting the regulation of existing gene products or existing genetic regulatory mechanisms or producing useful products that the host has adapted to use. But, these are the exception to the rule and not unexpected. The group of 4 reference you cited supports what I am saying.
You cited a reference that mentions ERVs involved in the placenta, just as Graeme Finlay covered in Part 2 of The Story in Our Genes. The ERVâs involvement in the development of the placenta in mammals is one of the most interesting stories of convergence in evolutionâit has happened repeatedly, each with different ERV infections wherein the sticky attachment protein of the virus was co-opted, as noted here where it starts âThe mammalian placenta is remarkably distinct between speciesâ. That they are âremarkably distinctâ is because the placenta evolved independently multiple times from the sticky protein of different ERV infections in one of the most remarkable examples of convergent evolution. See Retroviruses, the Placenta, and the Genomic Junk Drawer.
ââRemarkably, exogenous retroviral envelope (env) genes therefore have been integrated independently and adapted for similar essential placental functions via a convergent evolution process. â
âSyncytins are envelope (env) genes captured from ancient retroviruses that âendogenizedââintegrated into the germ-line chromosomes of an ancestral hostâmillions of years ago and since then have been transmitted in a Mendelian fashion from one generation to the next (1, 2). Six syncytin genes have been identified so far in primates, muroids, leporids, and carnivores (Fig. P1). These genes were captured independently from unrelated retroviruses that endogenized in distinct mammalian lineages and have been co-opted for a role in the formation of the placenta via a process of convergent evolution. We recently demonstrated through genetically modified mice that these genes are required for placenta formation and embryonic survival (3), and we further proposed that this stochastic acquisition of genes may have been pivotal in establishing the remarkable variability of placental structures among mammals.â PNAS Plus: Captured retroviral envelope syncytin gene associated with the unique placental structure of higher ruminants - PMC
This is part of abundant evidence for convergence in evolution where the same features of life evolve independently in diverse organisms. Think how many animals can fly for example. Bees fly, birds fly, mammals (bats) fly, etc., and none has a common flying ancestor. Bats are called âbirdsâ (Deut 14:11-18) in the Bible, BTW. Thatâs just one of many examples that show the Bible wasnât talking in scientific terms the way we do now, i.e., it isnât a book of science.
See here and, for thousands of example of convergent evolution, see here.
Simon Conway Morris, who is NOT and ID theory advocate but is a Christian argues that the ubiquitous examples of convergence in evolution is evidence that there is far more predictability of coming-up with the features of life, including beings like us, than most scientists are willing to recognize. Oddly Richard Dawkins agrees. See âWhat if Evolution Mean High Intelligence and an Advance Civilization Were Inevitable?â, linked to above.
How ironic is it that the worldâs most notorious atheist, Richard Dawkins, makes it possible for me to be an intellectually fulfilled Christian?
(3) Other good resources refuting this the âFunctionalâ ERV argument are here, here and IDiots and ERVs and in Friendly Viruses: The Special Relationship between Endogenous Retroviruses and Their Host
In response to me saying, that molecular fossils can be used as molecular clocks to estimate to how long ago the infection occurred based on known average mutation rates, you say:
You argue âif neutralâ. But, you apparently missed that they controlled for neutral ERVsâthat was the a main point of the molecular clocks reference.
Further most are neutral. Most ERVs in humans lack functions, and hence have decayed since being inherited from a common ancestor with other primates. Those few that have not are believed to have a functional role. See Phylogenetic Analysis Reveals That ERVs âDie Youngâ but HERV-H Is Unusually Conserved.
Thatâs why they âDie Youngââthey tolerate extensive mutations because they are neutral and have no function. Of course, itâs possible that some ERVs taking up space where they inserted in the genome still up or down regulates the expression of some host gene(s) in a beneficial way. But, that wouldnât preclude the ERV sequence itself from mutating as it if was neutral.
See the amazing tree of ERV-Fc going back 50-60 million years in both primates and other mammals in this reference --A Family Tree of a Retrovirus Group: The genomes of nearly 30 mammals that exist today harbor traces of ERV-Fc, a group of viruses that existed between 15 and 30 million years ago.
The only way to reasonably explain the ERV data is with deep time and common descent through evolutionary processes, processes we, accordingly, expect were Godâs chosen tool to bring about His purposes.
You assert that man is closer to orangutans than chimps. While there is a report of a recent study purporting to show closer similarity in one part of the genome between orangutans and humans and orangutans males are attracted to human women, it is misleading to something like that when other experts in the field still think it is âwacky ideaâ.
Iâm not saying they arenât, but even if the recent phylogenetic trees made from ERVs arenât 100% accurate, especially among such closely related species, that doesnât change the fact that the ERV data is overwhelmingly convincing evidence for common descent. Rats and mice, BTW, have more genetic diversity between them than do humans, chimps, bonobos, gorillas and orangutans between each other.
In addition to Graeme Finlayâs materials cited before, this 2004 reference, which may be a bit dated in minor aspects, is a good intro to ERVs as fossils in our DNA for those who are interested in reading further.
