Claudina of the precambrian for example, would is an early annelid bilaterian, transitional precursors to metazoan bilaterians today. They also are of the earliest shelled organisms we know of with evidence of predation, backing the evolutionary arms race explanation for why the ediacaran and Cambrian explosions occurred (along with climate related changes such as the rifting of rodinia and end of snowball earth).
Claudina as an Early Annelid Bilaterian?
You claim that Claudina (likely referring to Cloudina) is an early annelid bilaterian (a segmented worm-like animal with bilateral symmetry) and a precursor to more complex Cambrian animals.
-Cloudina is not an annelid bilaterian; it is classified as a small, tube-dwelling organism from the Ediacaran period.
-It lacks clear evidence of complex body structures like a digestive system, segmentation, or limbs—features seen in Cambrian bilaterians.
-Some researchers suggest Cloudina may be related to early cnidarians (corals and jellyfish) rather than bilaterians.
-If Cloudina was a true precursor to Cambrian bilaterians, we should expect to see intermediate forms between Cloudina and Cambrian phyla, but these are absent.
Cloudina does not demonstrate a clear evolutionary link to Cambrian bilaterians, making it a weak example of a transitional fossil.
Evolutionary Arms Race & Predation Evidence
You argue that predation (seen in Cloudina) led to an "evolutionary arms race," pushing rapid evolution during the Cambrian Explosion.
-While some Cloudina fossils show tiny boreholes (suggested as evidence of predation), this does not explain why so many completely new body plans appeared so suddenly.
-Predation could explain why organisms developed shells or defenses, but it does not create entirely new phyla (e.g., arthropods, mollusks, chordates).
-The major challenge for Darwinian evolution is not just explaining adaptation (defensive shells), but the origin of complex body plans and genetic information. (Irreducible complexity which I will get to in my next post)
-If an arms race drove rapid evolution, we should see a gradual buildup of complexity in the fossil record before the Cambrian. Instead, we see an abrupt appearance.
Predation does not explain how entirely new animal phyla appeared with no clear evolutionary ancestors.
Climate Change (Rodinia Rift & Snowball Earth)
You are arguing that geological events (the breakup of Rodinia and the end of "Snowball Earth") triggered evolution.
-While environmental changes can create new ecological niches, they do not directly explain the appearance of new genetic information or body plans.
-Simply having a good environment does not automatically produce new functional genes, proteins, and organs.
-If climate shifts caused the Cambrian Explosion, why didn’t similar environmental changes in other periods cause equally explosive biological diversification?
Environmental changes might create opportunities for life to expand, but they do not explain the sudden, coordinated emergence of complex animal phyla.
The real issue is not whether evolution occurred at all but whether it can adequately explain the sudden emergence of complex body plans.
The Cambrian Explosion is a challenge for gradual evolution because:
1. New phyla appear suddenly with no clear ancestors in the fossil record.
2. Genetic information required for new body plans must come from somewhere, and random mutation + natural selection has not been shown to create such complexity so quickly.
3. Transitional fossils leading to Cambrian phyla are missing, making the "step-by-step" evolutionary process unclear.
The Cambrian Explosion presents a major challenge for evolutionary theory. While Cloudina and predation do not explain the rapid, coordinated appearance of entirely new animal body plans. The sudden emergence of these complex organisms suggests that standard evolutionary mechanisms (mutation and selection) are insufficient to account for the diversity seen in the Cambrian period.
or example, let's look at elephants of the fossil record
I'd defer to examples like the one given above that descent with modification simply makes more since than like a punctual creationism (if that's even what anyone would call it).
neither do I believe that God created every living species.
I see elephants mating with elephants to make elephants. There was no change from elephant to another animal. We do see changes in the shape, colour and size. But that is simply natural selection and adaptation.
God originally created animals with a rich variety of genetic information, allowing for the diversity of species and breeds we see today. This idea is sometimes called "created kinds" (baraminology) and suggests that God made original "kinds" of animals with the built-in potential to adapt and diversify over time.
You may ask how this would work genetically?
1. Front-Loaded Genetic Diversity
-The first animals (like the original "dog kind" or "cat kind") were created with all the necessary genes for future variations.
-This means they had genes for different colors, sizes, fur lengths, and other traits already inside them.
-Over time, different combinations of these genes were passed down, leading to the many breeds and species we see today.
2. Microevolution, Not Macroevolution
-New Earth Creationists accept microevolution (small changes within a kind) but reject macroevolution (one kind turning into a completely different kind).
-Example: All dogs (wolves, foxes, Great Danes, and Chihuahuas) came from the same created "dog kind," but a dog never became a cat or a horse.
3. Natural Selection & Adaptation
-As animals spread into different environments, certain traits became more common.
-Example: Wolves in colder climates developed thicker fur because those with genes for thick fur survived better and passed on those genes.
4. Selective Breeding Accelerates Change
-Humans have used artificial selection (breeding) to bring out specific traits, like making sheep with more wool or dogs with certain temperaments.
-This process works because the genes were already there—they were just "sorted" into different combinations.
God designed animals with a built-in ability to produce variety within their kind. This explains why we see so many different breeds today, but always within the same basic type of animal. So, this is why we see elephants become elephants in your diagram.
And yes, I'll reiterate relation to YEC views, because the concept of "kinds" doesn't even make sense in an OEC view.
Correct. An OEC struggles with it as they do not believe what the Bible says. They try to explain it away as though it is silly or just poetic.
Genesis 1:11-12 (ESV)
"And God said, 'Let the earth sprout vegetation, plants yielding seed, and fruit trees bearing fruit in which is their seed,
each according to its kind, on the earth.' And it was so. The earth brought forth vegetation, plants yielding seed
according to their own kinds, and trees bearing fruit in which is their seed, each
according to its kind. And God saw that it was good."
Genesis 1:21 (ESV)
"So God created the great sea creatures and every living creature that moves, with which the waters swarm, according to their kinds, and every winged bird
according to its kind. And God saw that it was good."
Genesis 1:24-25 (ESV)
"And God said, 'Let the earth bring forth living creatures
according to their kinds—livestock and creeping things and beasts of the earth
according to their kinds.' And it was so. And God made the beasts of the earth
according to their kinds and the livestock
according to their kinds, and everything that creeps on the ground
according to its kind. And God saw that it was good."
The idea of the fossil record or the rock record being a product of a global flood also runs in contradiction with old Earth creationism.
That is because the Bible, God's word, is not your authority. Evolution is.
And if you agree that evolution is true to some extent
Microevolution, Not Macroevolution
-New Earth Creationists accept microevolution (small changes within a kind) but reject macroevolution (one kind turning into a completely different kind).
-Example: All dogs (wolves, foxes, Great Danes, and Chihuahuas) came from the same created "dog kind," but a dog never became a cat or a horse.
It's usually the fundamentalist types who have little to no tolerance for different interpretations, anoint themselves the apostate the police, and go around accusing and condemning everyone who dares disagree with them.
I would not have posted
Romans 1:20-24 if you had not asked me, "Where did you get the belief that evolution is a salvation make or break point? I don't remember any scripture saying that. Did you just make it up?"
I was just wanting a friendly conversation, but then you asked me for a verse and so I gave it. If you do not like the answer, then do not ask the question.
But if you are feeling condemned or guilty, then maybe there is a reason. A person does not need to feel guilty if they are innocent.
The example "above" shows the same kind... Elephant, and does not in any way describe the theory of evolution, by common descent.
What you are trying to explain is the difference between Microevolution and Macroevolution
New Earth Creationists accept microevolution. So small changes within a kind. Elephants becoming elephants that may look slightly different, but they are still an elephant. Like in the diagram shown above by Job. But we reject macroevolution. That is one kind turning into a completely different kind. So, fish turning into cats. LOL. That is Darwinian Evolution. (Sorry, couldn't help but giggle at that)
-Example of microevolution: All dogs (wolves, foxes, Great Danes, and Chihuahuas) came from the same created "dog kind," but a dog never became a cat or a horse.
