<<<<<<Does an Armless Fossil Shed Light on How Animals Like Snakes Lost Their Limbs?

I’ve used many words to describe evolution over the years, but I think I might have a new one which describes a recent fossil find: “disarming.” This pair of fossils (one of an adult specimen and one of a juvenile) of Nagini mazonense, a small snake-like animal (technically a molgophid recumbirostran) that supposedly lived about 308 million years ago, was discovered in the Francis Creek Shale of Illinois. The adult fossil specimen measures about 4 inches long (10 cm), and although it has reduced hind limbs, it has no pelvic girdle to support those limbs or front limbs. The more complete juvenile is around 2 inches (5 cm) long and also has no front limbs or pelvic girdle.
Now, the research journal that covered the fossil find constantly attributes this loss of genetic information as “evolution.” They point out that this fossil closely resembles how snakes and caecilians (legless amphibians) exhibit progressively reduced limbs before complete loss in their “evolutionary histories.” But today, there are living reptiles that have no arms but reduced hindlimbs (Pygopodidae—“armless” geckos and Chamaesaura—“grass lizards”). Maybe they just haven’t “evolved” enough yet!
The researchers described the proposed mechanisms behind limb loss in Nagini:
Although the mechanisms of limb reduction in many tetrapod lineages remain incompletely understood, it appears that limb reduction and loss can be accomplished by failures or disruptions to normal development during any of the three phases of limb development, resulting in a vast array of variation in limb-reduced phenotypes. Late phase disruptions to growth plate development, particularly the rate of longitudinal growth or timing of growth plate closure, are most common and typically lead to conditions where the majority of limb elements are retained but are reduced in overall size. Disruptions in limb morphogenesis and patterning during the limb bud phase will often result in loss of distinct limb modules, commonly the loss of entire digits but also the loss of other distal (but not proximal) elements, including carpals and/or tarsals. Failure in the earliest phase establishing the limb field is relatively rare but is the mechanism identified as resulting in the loss of the pectoral limb and girdle and associated musculature in caecilians and snakes and we suggest that this is the mechanism involved in forelimb loss in Nagini as well based on similarities in the pattern of limb loss (that is, complete lack of proximal appendicular elements and absence of a forelimb rudiment).
In other words, these are mutations in the developing reptile’s genes which disrupt its ability to grow limbs. (It is worth noting here that there is some debate among evolutionary biologists who differ on whether these recumbirostrans are reptiles or amphibians). This is a result of the curse (Genesis 3), not an evolutionary advancement. Or it may be that God designed these types of reptiles (or amphibians) as limbless or with reduced limbs originally (as part of the creeping things of Genesis 1:25).
Now to be sure, even in a cursed world, God allows some animals to adapt to their environment. And for burrowing or tree-dwelling animals, which many of the “legless lizards” are, not having limbs is not a detriment to their survival but may actually aid the animal.
Now to be sure, even in a cursed world, God allows some animals to adapt to their environment.
In any event, this is not molecules-to-man evolution but potentially a developmental mutation and the loss of information. Ironically, though, the researchers placed Nagini in a phylogenetic tree where both its ancestors and descendants are four-limbed recumbirostrans. How does this show an evolutionary developmental process in lizards or amphibians? It’s not just inconsistent: it’s totally disarming to their “story.”>>>>>>
Ok, got another one for ya.
The LCMS rejects evolution. So how to explain all the things that indicate evolution happens?
Be nice.Again, yet again, still one more time..... YES, the prevailing opinion in the LCMS is that the common understanding of the theory of Evolution conflicts with the Bible and thus is rejected. BUT (and here's the point that seems to thus far alludes you, my esteemed brother), this is not dogma, it is not binding doctrine. Nowhere do the Lutheran Confessions say a word about this. You will likely not be excommunicated from an LCMS member congregation if you personally agree with an understanding of the theory (although I suspect your pastor will disagree with you). Not every belief of LCMS persons is dogma. If you were Confirmed in the LCMS, you were asked if you agreed with Luther's Small Catechism (not any explanation of it but the actual Confession which is maybe 6 pages long), not if you reject some understanding of evolution or believe abortion is wrong or any other view common in the LCMS.

What do you think about what’s said in the article I posted above?What things are there that indicate evolution happens?
AFAIK every piece of evidence (data) out there can be used to explain things in a creation model vs evolution model. So the data is relatively meaningless, except that it does seem to fit very well with the creation model.
What do you think about what’s said in the article I posted above?
My Catholic Bible mentions something about the possibility of us coming from other life forms In the front commentary.I think it never mentions The Lutheran Church - Missouri Synod. Nor indicate that members of congregations that belong to the LCMS are bound to reject any science theory.

What do you think, Lamb?
Oh, I don’t either. I’m just looking for a permanent church home, which I may already have. I just worry that I don’t belong there if creationism is wrong.I don't think believing in Evolution or not should sway us as to whether we have faith in Jesus Christ.
Ken's article makes sense. The example of the tiny snake-like animal would not show anything evolving, but rather devolving in a loss of limbs. Generally, evolutionists will take an example of natural selection and say it is evidence of evolution, but it is not. Natural selection is just changes using existing genetic material, nothing new is created.What do you think about what’s said in the article I posted above?

More important is whether a person is a Bible-believer.Oh, I don’t either. I’m just looking for a permanent church home, which I may already have. I just worry that I don’t belong there if creationism is wrong.
And a devastating impact on human relations, society, politics, etc.
- “In an evolutionary mindset, sin doesn't exist. And if sin doesn't exist, if it can be explained away in the naturalism of the theory of Evolution, it has a devastating impact on the Gospel of Jesus Christ.”
If Evolution is Right, Can Anything Be Wrong?Atheistic evolutionists express moral outrage against murder and rape, but if evolution is true, how can there be moral outrage since it was killing and rape that got us where we are today as a species? Animals kill and rape every day. Why are killing and rape OK for animals but not for humans, who are only supposedly highly evolved animals? If evolution is true, at death we are nothing more than dust in the wind and in life we are nothing more than a bag of meat and bones.
My Catholic Bible mentions something about the possibility of us coming from other life forms In the front commentary.
True. It’s a NAB and not at all related to Lutheran teaching. However, now you see where I’m coming from, what with a Catholic background, still occasionally reading my old Bible. Though I only read it when I feel the pull to go back to the RCC.It seems likely that your Catholic Bible is not a part of the Lutheran Confessions, nor an official publication of The Lutheran Church - Missouri Synod. What it "says' and what the LCMS mandates of every member of every one of its parishes seem like two different things.

Quite a smart one too, I'm pickin'.I’m a woman.
Yes, the true church is all believers worldwide, no matter what denomination they are in. I don't think you can find a denomination you will agree with 100%, so you have to find one that is close and go with it.Quite a smart one too, I'm pickin'.
The main thing is belonging to the Body of Christ.
Eph 4:4-6 There is one body and one Spirit, just as you were called in one hope of your calling; (5) one Lord, one faith, one baptism; (6) one God and Father of all, who is above all, and through all, and in you all.
Heb 12:22-24 But you have come to:
- Mount Zion and to the city of the living God,
- the heavenly Jerusalem,
- to an innumerable company of angels, (23)
- to the general assembly and ekklesia of the firstborn who are registered in heaven,
- to God the Judge of all, to the spirits of just men made perfect, (24)
- to Jesus the Mediator of the new covenant, and to the blood of sprinkling that speaks better things than that of Abel.
