I recommend you read and heed:
http://www.answersingenesis.org/Home/Area/faq/dont_use.asp You're current argument is on that list with this comment:
‘There are no beneficial mutations.’ This is not true, since some changes do confer an advantage in some situations. Rather, we should say, ‘We have yet to find a mutation that increases genetic information, even in those rare instances where the mutation confers an advantage.’ For examples of information loss being advantageous, see Beetle Bloopers: defects can be an advantage sometimes, New eyes for blind cave fish? and Is antibiotic resistance really due to increase in information? Of course the "no new information" bit is bogus too but we can get to that later. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

You obviously did not read the article for content. Go back and try again. Look at who is posting that site. Do a little research.
There are instances where organisms have lost a trait and then evolved it again. If both are "losses of information" that is not possible. Being blind in an environment where there is no light means that the energy spent on developing and maintaining eyes can be used for something else, like smell, that can help find prey or evade predator. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

Then when you have finished reading the AiG page on what mistakes not to make, you can graduate to some science specific sites.
As regards information increase this oneApolipoprotein AI Mutations and Information It is long and rather technical and you can skip to the end conclusion, but the discussion does show that information must be increased by this mutation. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

which in turn is made dominant through natural selection (NS). Many, if not most, evolutionists believe that this is the way in which evolution operates. First off, genetic traits don't have to be dominant to affect a population. The sickle cell mutation is one that causes blood cells to be shaped like a sickle instead of the normal round shape. It is a recessive gene, so a person with one copy does not have the bent shaped blood cells. When a person has the gene from both parents, then the blood is affected and the result is lethal. Those with one copy have higher survival rates when subject to malaria as compared to people with no copies. Second, mutations are not "made dominant" as they occur on dominant and recessive genes alike and the {dominance \ recessive} character is not normally changed by the mutation. Third, most mutations are not immediately relevant to survival and many may be neutral to survival and thus unaffected by natural selection. Finally, this is such a poor statement of any of the principles of evolution that you will not find any evolutionists using it to describe the process of evolution and does not include other mechanisms by which species change over time. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I don't think that's what he meant (1) let him speak for himself instead of second guessing eh? (2) The word used was dominant, and that word has specific meaning in biology, especially when talking about inheretance of characteristics. Part of the problem with communication is the misuse of words. My point was that the phrase as written was not what a biologist would say. a trait is not "made dominant" rather a trait becomes more common through the process of natural selection. and it doesn't have to become the most common in a population either, it can remain in a varietal subset of the population that eventually accumulates with other changes to cause a speciation separation from the general population. All natural selection says about a mutation is that it survives while the surviving members possibly having an advantage or a disadvantage to future survival, but just as likely neutral initially. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

because we don't count all the non-viable fetuses that never make it why stop there? what about all the eggs that were not fertilized due to mutations possible to {sperm \ egg} so incompatable? we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I don't know how they evolve in insects Look for work done by Dr. James H. Marden and Stone Flies. I ran into this last year and found it interesting.

is one site, the one I remember had an animation that was well done. enjoy. we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

I think Dawkins talked about how many mutations in a set time were required ... might have been in Blind Watchmaker. Not many was his result (which of course is totally unbiased ... )

There are also arches formed by the 'non-arch' material falling away from the remaining arch by natural {weathering \ erosion} processes without the need of an intelligent scaffold entity, and not just solid arches but ones built of rubble where the bottom has been removed and the jumble above is interlocked ("bridged"). Such "natural" bridges sometimes allow people to be rescued from earthquakes.
They are also at a lower state of energy from before, so entrophy has increased even though a simple structure (wall) has become a more complex structure (bridge). we are limited in our ability to understand by our ability to understand RebelAAmerican.Zen[Deist

What has acted on the stone arch to make it assemble? Natural selection can not account for it, as natural selection can only take away thing. you tell me eh?
Notice the appearance of a bridge assembled from smaller stones ... the appearance of an intelligent scaffold architect?
Intelligent Design makes more sense to me, but that's for another thread. try: http://EvC Forum: Is ID properly pursued? -->EvC Forum: Is ID properly pursued? enjoy.
