You don't need to increase complexity for evolution.
Although at some point evolution theory does demand it, since everything evolved from a single cell. At present there is no mechanism to describe this magical increase in complexity (first you will have to observe this phenomenon, which at present has not been observed), or maybe i haven't searched hard enough... Would be nice to observe it though.

This is still evolution, they do not have to become eukaryotic or archeobacterial to evolve.
Although it looks like everything is becoming dysfunctional due to mutation, unless that dysfunctionality lends it a survival edge.

Pharyngeal arches are considered remnents of gills as they are the basis of gills in fish.
Don't know how you got to that one. Pharyngeal arches in fish lead to gills, Pharyngeal arches in human embryos lead to the thymus, parathyroids, and the middle ear canals. Exactly how are they related?

The appendage was located under and behind the last sacral vertebra suggesting a true vestigial tail with a delayed process of regression.
This so-called "human tail vestigial" is actually a dorsal cutaneous appendage as a result of defects of closure of one or more vertebral arches, which may be associated with malformations of the spinal cord, nerve roots, congenital fibrous bands, lipomas, and congenital cysts. It is a defect in development, not a return to our "ancestral form", and is a marker for spinal dysraphism.
Donovan DJ, Pedersen RC. Human tail with noncontiguous intraspinal lipoma and spinal cord tethering: case report and embryologic discussion. Pediatr Neurosurg. 2005 Jan-Feb;41(1):35-40.
The so-called "tail" during development actually has a function. During development, the spine is at first longer than the body because the muscles and limbs do not develop until they are stimulated by the spinal nerved. So the spine must grow and mature enough that it can send out the proper signals for muscles, limbs, and internal organs to begin their growth. For this reason, the spine at first is bigger than the limbs, but later the arms and legs become largest. It is therfore not a useless "vestigial tail".

Anything to say on the webbed feet and hands we have during development?
Since all animals with hands and feet have those during development, why would it be vestigial? Hox genes (unique to each animal) control the breakdown of these structures by inducing apoptosis.

Yes but you can not survive with no Kidneys, you can survive with out an appendix,
You survive without a stomach as well...
QUOTE
Your arguement for the nose does not stand at all.
Why not? Should we go through the exercise of why the stomach is vestigial as well?

The appendix is still believed to be associated with the cecum however.
Even though it is a separate structure. Guess the appendix is as much associated with the cecum as the small intestine is.

What about body hair and male nipples?
Exactly how does evolution explain male mammal nipples? According to evolutionary theory, the male/female differentiation evolved much earlier than mammals are supposed to have evolved from reptiles. That is, there were allegedly already males and females long before females evolved breast-feeding. Incidently, male nipples have a function during development. Mammalian embryos contain characteristics of both sexes at first, because they all have basically the same genetic information, and this information is expressed as efficiently as possible as the embryo develops. For example, in all human embryos, at first both the müllerian duct system (female) and the wolffian duct system (male) develop, because both sexes have the genetic information for these structures (a features creationists term "design economy" and "efficient embryological development"). The subsequent differences are the result of designed chemical signals that control the expression of the information. E.g., a gene set usually found on the Y chromosome controls the levels of testosterone and dihydroxytestosterone (DHT) secretion. Above a certain level, these hormones suppress the development of the müllerian duct system and promote the wolffian duct system, so the embryo takes on masculine characteristics. Below a certain hormone level, the opposite happens, and the embryo takes on female characteristics. Male nipples respond to these higher levels of androgens. Nipples aren't evidence for evolution (how does evolution explain it?) and not evidence against creation.
According to evolution theory, human hair is useless and humans won't have hair in a few generations as it is vestigial and useless.
However:
Human body hair, which covers almost the entire body, has a functional advantage over other mammal hair in that it has a high degree of touch perception, which occurs when a hair is moved or bent.
Hair on top of your head covers the spot where about 40% of heat dissipates. Fine body hair also plays an important role by extending the boundary layer, preventing excessive skin loss.
When you perspire, or sweat, the hairs grasp the sweat and keep it near you. This will keep your body cooled.

It may degredate out of a cell in our atmosphere, however the current atmosphere is extremely different to that of the atmosphere over 3 billion years ago, so you can not compare. In the cell it does replicate its self however.
There is no consensus on what the atmosphere was like 3 billion years ago. Some say oxidized form, some say reduced form. DNA does not replicate by itself... You are right, it does replicate itself through a very complex mechanism that does need RNA, DNA, proteins and a temperature and pH regulated environment.

Ah, the RNA world hypothesis, very interesting. The best hypothesis so far but with enormous, near impossible, hurdles to overcome. Do hope they come to a conclusion sooner rather than later.

Changing of pre-existing genetic information? Mendelian genetics?

But it has to be presumed to have started somewhere would it not? This has some basis behind it, we know such conditions exist and the is life that can survive such conditions.
So what are you thoughts on the origin of life? Where did it come from?
Life must be there to survive such conditions. Which conditions are you referring to?
My thoughts on the origins of life:
Science tries to explain origin of life in a naturalistic manner, but can't at the moment (abiogenesis), although it is believed that the fossil record points out that it is a given, which is not scientific.
Creationism explains life as the result of purposeful design created by a creator. Non-naturalistic, although as indirect evidence they will point to the genetics as a code and that all codes requires a creator, as well as as irreducible complexity. Some creationists believe that the fossil record also prove creationism, and that it is just a matter of interpreting the evidence in the "correct" manner.
Both belong to the realms of philosophy at the moment in my opinion.
For the moment i like science.
