@disgruntledgamer
First of all I want to apologize, that I implied that you were a troll. I assumed that since this topic is normally troll-bait, but you seem to take the matter quite seriously.

Actually it is. I'm not going to repost the evidence you can just look back what I and other people have shown, but I suspect no matter how much evidence proof or facts I give you won't chage your mind as you seem to have made it up before getting to the starting gate.
Once again, I know the evidence. I might not be as educated in this matter as I want to be, but I wrote what I wrote on the basis of the facts I know, the evidence I know about evolution and natural selection. I don't think, that we should abolish the theory of evolution and believe that god did it. That would be very cheap from a scientific perspective. But on the other hand it is very dangerous to defend a theory in a way you do. It stifles scientific advancement as much as the silly right wing extremist christians you have over there in the USA.

- snip - something about the difference between modification and mutation
LoL I love how you give an example of evolution and than call it Modification without actually explaining what you consider to be modification on a molecular level. Also you're wrong Substitution, Addition and Deletion mutation can cause new information and can cause things like fur color change, the pocket mouse is a good example. Your attempt to redefine evolution and give it a new name is laughable.

Maybe we are not on common ground with the terminology. I am not a native speaker (as you might have guessed from my english ;-) ) and technical terms are exspecially hard in this regard. What I mean by "modification" is the recombination of genetic material on a molecular level, when the ovum and the sperm cell are created. As far as I recollect, the two genetic sets of the mother and the father are combined from the haploid chromosome sets in the ovum and the sperm cell to create the normal diploid chromosome set. Additionally, single allels from both haploid sets are exchanged betwen the chromosomes, creating new configurations of the given genes.
Like this, the given information is recombined in a new context, creating new characteristics of a given trait. Again (as far as I know) these are the mechanisms on which breeding is based, therefore the reference to Gregor Mendel. But (also again afaik), we cannot breed new species, since this would require mutation and creation of completely new genetic material.

-snip- trying to make a vain point about the theory of evolution beeing not as solid as it seems (may have picked a better example)
You obviously didn't watch the video I provided on my first post as it answers your issues completely, and it is a stronger theory than gravity whatever you want to admit it or not. The reasons have already been explain on the first couple of pages.
Again, how can you say that? What "theory of gravity" are we talking about? The Newton model works quite well, as it is descriptive, not a theory, but law. If you mean the theory "why and how is there gravity", you are right, we are far from understanding this; But this is not quite a point for the solidity of the theory of evolution, it's liek saying "this is not as bad as that". It could still be pretty bad.
What I wanted to show with my example is, that for example the "hard fossil evidence" is not as hard as often quoted. There are holes, big holes, and anyone who claims otherwise is ignoring the facts.

-snip- about information in the DNA and repair mechanisms
Reading the first couple pages of a wikipedia pages does not make you an expert. Yes we have mechanisms like Polymerase that repair DNA but it's not full proof. And when these fail it can result in a beneficial, silent or harmful mutations.
A good example of this is Nylon-eating bacteria, Which resulted from a frame-shift mutation which added information. Now since Nylon wasn't invented until 1935......... You get the picture, we have also duplicated this process in the lab in other bacteria such as Pseudomonas aeruginosa which got to evolve to break down Nylon. However Pseudomonas aeruginosa did not use the same enzyme as Flavobacterium strain.
My knowledge about the repair mechanisms results from reading books about the topic and my biology course in ... highschool? College? Whats the equivalent to the german "Oberstufe" (year 11 to 13)? I quoted the wikipedia page to show, that I have a point, like you quote quite a lot YouTube Videos to show, that you have a point.
Your example of the nylon eating bacteria is a very good example of a beneficial mutation. Another often quoted example is sickle cell anemia in parts of africa with a high risk of malaria, since the anemia increases the resistance to the sickness. I would like to have a source of the nylon eating beeing a mutation and not a recombination of given genetic material (I want to have to source to read it, not to prove you wrong, this is interesting new information for me). Nylon is, after all, a hydrocarbon and therefor not unsimilar to the normal diet of bacteria.

-snip- about the possibilities of "good" and "bad" mutations
This is a classical definition of a Straw-Man. You built up this made up flawed position and than attempted to tear it down. An argument I might add that isn't even your own as I've seen this example used and debunked before. Sorry but it's not going to work mutations aren't tornado's running through a junk yard and evolution isn't random. You completely ignored natural selection either because you don't understand it or you purposely ignored it.
Evolution is like trying to pick a sequence of lets say 9 numbers. Picking all 9 numbers in the first shot is highly unlikely, but natural selection allows you to save the numbers you get right. Try it it doesn't take that long.
I am sorry, that you don't like my example ;-) I think, you quite misunderstood. The point I wanted to make is, that harmful mutations are much more likely than useful mutations. So even if you get an organism with a useful mutation, it is very likely be destroyed by a harmful one.
I do understand natural selection, and in my book, it is indeed random. But maybe we are again mixing up terms. The mechanisms, by which one trait survives and the other not are non-random. They base on pure logic. If one individual is faster than another one of its species, it can outrun predators and is more likely to reproduce. But the creation of new traits by mutation are in fact completely random. Which brings us back to the tornado. To create a completely new trait, that is visible, beneficial and therefore relevant for the process of natural selection, is highly unlikely. Were are not talking about taking a 9 digit number, the numbers are a little bit higher (not the bullshit in the video, which makes the fun of creationists they deserve, but still very unlikely). And unlike your statement there is a high possibility of reversing the process, like the loss of an accumulated silent mutation due to the death of the carrier or the destruction of the mutation by a "bad" mutation.

We don't even have to go as far as looking as the chemistry of large molecules, amino acids in particular, to support my point.
I'm pretty sure your point would just be another copy and pasted Straw-Man wall of text, so I might as well debunk it now and save you the time, it's a combination of chemical reactions and thermodynamics.
I am sorry, but your video does nothing to disprove my point. I am talking about a book about macro molecule chemistry; unfortunately it is written in german, therefore not easy to find digital quotes ("Das Molekül und das Leben" if you want to look it up). Its about several properties of amino acids and large hydrocarbons, which make it near impossible for most of the processes required in the process of the elongation of DNA (which has, afaik, still to be proven today, but please give me the information you have (!= YouTube videos), if I am wrong).

I will not start a debate about the spontaneous ermegence of life, since this thread only discusses evolution, but this would also an interesting topic to further develop my thesis.
I'm sure your YEC school will be proud, but in reality.
I will ignore your obvious provocation (most of all for the reason, that you are assuming to much) and post some questions about the video. One of the presented facts stumped me. Is it possible for RNA to spontaneously reproduce itself? As far as I know, does any kind of RNA or DNA need outher mechanisms to duplicate and transcribe. Also concerning the mentioned experiment, as far as I know were some amino acids created in the process of the experiment, but not the necessary four Guanin, Thymin, Adnin and Cytosin. I'd like a better source here... There are other flaws in the presented theories. As the narrator explains, the theories are still in its infancy, but on the same breath calls anyone an idiot, who thinks otherwise? Not quite scientific thinking in my book.

TL;DR:
What I want to say is, that you have to be careful, what you call a "fact". You have to check everything you are given as a fact today, because there are to many people trying to enforce their own agenda.
I don't want you to run into the curches, I want you to run to your books (or even wikipedia might be a good start). Check your facts, check the people that are giving them to you and start thinking for yourselves. Please please please, for the sake of humanity...
I am very careful what I call facts and I do check them, the fact you don't like that they're facts is irrelevant. Your misconception and disinformation isn't changing that they're facts. I've debunked your copy and pasted creationist mombo jumob before and will continue to do so. Also I rarely use wikipedia I prefer to use more credible sources.
I don't know, why you think, that your mix of youtube videos, condescending behaviour and sarcasm would disprove any of the points I have made. My knowledge is, as I said, from what I learned at school and what I gathered from various book sources of biology, chemistry, informatics, physics and a good portion of common sense. I always try to be open minded and include any valid argument in the range of possibilities. If you start to exclude some theories in favor of another, you stop to think scientifically. Thats all I want to say. I know the climate you are coming from. There are many idiots out there who claim stupid things. I thought that I am not one of them. I am not trying to prove God or any illogical thing like that, only show that the theory of evolution in its current state is not as solid as some people want it to be.
There has much work to be done. On the other hand, people that are just saying "god did it" are not scientific either. If that was the answer to anything, we could stop and try to understand our amazing universe.
The believe in god and scientific research are no antagonists. It only gets bad, if you try to disprove one with another, since this does not make sense either way.
So, please, could we come back to a scientific discourse, ignore the extremists and try to find the truth?
