Embryonic and fossil evidence proves that the human middle ear evolved from the spiracle of fishes. However, the origin of the vertebrate spiracle has long been an unsolved mystery in vertebrate evolution.
It seems that evolutionists have a much softer definition of what amounts to proof than in other fields of science.
Many important structures of human beings can be traced back to our fish ancestors, such as our teeth, jaws, middle ears, etc. The main task of paleontologists is to find the important missing links in the evolutionary chain from fish to humans.
The spiracle is a small hole behind each eye that opens to the mouth in some fishes. In sharks and all rays, the spiracle is responsible for the intake of water into the buccal space before being expelled from the gills. The spiracle is often located towards the top of the animal allowing breathing even while the animal is mostly buried under sediment.

In the Polypterus, the most primitive, living bony fish, the spiracles are used to breathe air. However, fish spiracles were eventually replaced in most non-fish species as they evolved to breathe through their noses and mouths. In early tetrapods, the spiracle seems to have developed first into the Otic notch. Like the spiracle, it was used in respiration and was incapable of sensing sound. Later the spiracle evolved into the ear of modern tetrapods, eventually becoming the hearing canal used for transmitting sound to the brain via tiny inner ear bones. This function has remained throughout the evolution to humans.

So this amounts to “proof”. By such means of rationalization, the ability of the geocentric model of the solar system to make approximate predictions of the location of the planets would constitute proof of that plausible but completely incorrect model.
These people can’t be normal …. That is for sure …
This stuff is pretty basic comparative vertebrate anatomy taught in every biology department in the world. It’s also a classic example of creationists constantly trying to move the goal posts every time a gap is filled in identifying “missing links.” The more biology and paleontology progress on the fossil record, the more deficient it becomes for creationists. You can lead a horse to water………

Goal posts aren’t moving. I’m not convinced that fish gills decided – through blind, unguided chance – to evolve into anything, much less the human middle ear.
A smart programmer will reuse smart code.
But sometimes with some changes to fit the purpose.
“every time a gap is filled in”
The gap wasn’t filled in, there are more gaps now.

So, evidence for a common design is evidence for universal common descent?
I would love to see the evidence that blind and mindless processes produced the mechanisms required for the processes of developmental biology. That includes meiosis. Without that all evos have is to beg the question.
I have not seen any progress in the last 7 years. On the other had the ID guys continue to make progress with new molecular evidence. Comparing morphology means little until you can explain how the component is built at the cellular level. What is taught in the classroom is sometimes indoctrination not science.
“However, the creationist Dr. Jerry Bergman explains homologies and analogies this way.
The simplest and most obvious explanation for the fact that morphological similarities between bones, sensory organs, lungs, or gills exist among most higher animals is that the requirements of life are similar for similar living things, and some designs are preferred in constructing animals because these designs are superior to competing designs. (Jerry Bergman, “Does homology provide evidence of evolutionary naturalism?,” TJ 15:1, 2001, pp. 26–33, available online at http://www.answersingenesis.or.....aturalism/)

I’ve been wanting to read the book “Billions of Missing Links”. Just the supposed transitions from fish to humans … how many mutations and how many missing links? Millions?

as to pretty basic comparative anatomy:
Published June 2022 at Phys.org:
Fooled Darwinists … no way :)))) at least, this Darwinist is honest enough to admit it, and basically confirms a common design …

Convergent evolution is a form of special creationism. Each body plan and feature created separately by God.
