More Strong Evidence for Evolution: Anatomical Vestiges

Taxonomy26 · May 26, 2016

Another Evidence of Evolution.
Part of the overwhelming body of such.
As with DNA, life can traced to a continuum, with many creatures, including us, having anatomical vestiges of our evolutionary ancestors.
An immaculate 'creation' event wouldn't leave useless organs/etc.

Prediction 2.1: Anatomical vestiges

Some of the most renowned Evidence for evolution are the various nonfunctional or rudimentary vestigial characters, both anatomical and molecular, that are found throughout biology. A vestige is defined, independently of evolutionary theory, as a reduced and rudimentary structure compared to the same complex structure in other organisms. Vestigial characters, if functional, perform relatively simple, minor, or inessential functions using structures that were clearly designed for other complex purposes. Though many vestigial organs have no function, complete non-functionality is not a requirement for vestigiality...
[.......]
Geoffroy was at a loss for why exactly nature "always leaves vestiges of an organ", yet he could not deny his empirical observations. Ten years later, Jean-Baptiste Lamarck (1744-1829) identified several vestigial structures in his Zoological Philosophy.
[.......] these "Hypocritical" structures profess something that they do Not do—they clearly appear designed for a certain function which they do Not perform. However, Common Descent provides a scientific explanation for these peculiar structures. Existing species have different structures and perform different functions. If all living organisms descended from a common ancestor, then both functions and structures necessarily have been gained and lost in each lineage during macroevolutionary history. Therefore, from Common Descent and the constraint of gradualism, we predict that many organisms should retain vestigial structures as structural remnants of lost functions. Note that the exact evolutionary mechanism which created a vestigial structure is irrelevant as long as the mechanism is a gradual one.

Confirmation:
There are Many examples of rudimentary and Nonfunctional vestigial characters carried by organisms, and these can very often be explained in terms of evolutionary histories. For example, from independent phylogenetic evidence, snakes are known to be the descendants of four-legged reptiles. Most Pythons (which are legless snakes) carry Vestigial Pelvises hidden beneath their skin.. The Vestigial pelvis in Pythons is Not attached to vertebrae (as is the normal case in most vertebrates), and it simply floats in the abdominal cavity. Some lizards carry rudimentary, Vestigial Legs underneath their skin, undetectable from the outside...
Many cave dwelling animals, such as the fish Astyanax mexicanus (the Mexican tetra) and the salamander species Typhlotriton spelaeus and Proteus anguinus, are blind yet have rudimentary, Vestigial eyes....
[.......]
The ancestors of Humans are known to have been Herbivorous, and molar teeth are required for chewing and grinding plant material. Over 90% of all adult humans develop third molars (otherwise known as Wisdom Teeth).
Usually these teeth never erupt from the gums, and in one Third of all individuals they are Malformed and Impacted. These Useless teeth can cause significant pain, increased risk for injury, and may result in illness and even death.

Another Vestige of our Herbivorous ancestry is the vermiform appendix. While this intestinal structure may retain a function of some sort, perhaps in the development of the immune system, it is a rudimentary version of the much larger caecum that is essential for digestion of plants in other mammals..."

Yet another human Vestigial structure is the Coccyx, the four fused caudal vertebrae found at the base of the spine, exactly where most mammals and many other primates have external Tails protruding from the back. Humans and other apes are some of the only vertebrates that lack an external tail as an adult. The coccyx is a developmental Remnant of the embryonic tail that forms in humans and then is degraded and eaten by our immune system ... Our internal tail is Unnecessary for sitting, walking, and elimination (all of which are functions attributed to the coccyx by many anti-evolutionists). The caudal vertebrae of the coccyx can cause extreme and unnecessary chronic pain in some unfortunate people, a condition called coccydynia. The entire coccyx can be surgically removed without any ill effects (besides surgical complications)...

It's rather old news.
If I understand correctly (and I hope I do) vestiges were invented by God just for fun. To have a good laugh at expense of dumb evolutionary scientists. It's tough to survive eternity without a good laugh.

Obviously Not to the people it's aimed at

Yes, similar to the extensive Fossil Record.
It gods attempt to test their faith by planting overwhelming evidence only a true/blind believer can ignore.

One interesting anatomical vestige deals withe the recurrent (inferior) laryngeal nerve.

This nerve is traced back of early fish, where it went from the brain, passed some blood vessels near the heart and then to the gills. In fish, this is a short path. When amphibians and reptiles evolved from early fish, the nerve remained and added function for controlling breathing, swallowing and the larynx. Mammals inherited it even later. With the development of necks, the nerve continued to go down the neck, around the same blood vessels near the heart and back up the neck to the larynx. In the giraffe, the nerve is about 15 feet long, when the direct route (brain stem to larynx) is a few inches.
