Again, I have no problem believing that sex is an advantage. Your articles seem to focus on the benefits of sex and why sex evolved.To say that no beneficial mutations add genetic material is nonsense. Whoever told you that is ignorant or lying. Both insertions and duplications can be beneficial; and duplications are a major source for new genetic material. Read this:
evolutionpages.com/Streptomyces.htm
Also this:
evolutionpages.com/Mouse%20genome%20proteins.htm
particularly the section under ‘gene familes’
As for the evolution of sex, this will tell you something about it . You won’t be able to see the full articles unless you are a subscriber, but the abstracts are interesting:
nature.com/nrg/focus/evolsex/index.html
Here is asimilar review in Science with similar constraints to see the entire papers:
sciencemag.org/cgi/content/summary/281/5385/1979
Here is another paper:
pnas.org/cgi/content/full/98/24/13774
When you’ve finished reading and digesting this material would be a good time to come back.
I guess you know that some bacteria exchange genetic material and that they have ‘sexes’?
Of course there are a lot of hard scientific problems with the evolution of sex and there’s a lot we don’t know about it. But you are just making the old tired ‘Argument from Personal Incredulity’.

My problem stems from the impossibility of such a thing arising.
One of the biggest problems is that most websites say that it is because of conditions in the environment that something evolved. I.e massive pressure from predators cause an asexual cell to evolve into one which has sex in order to increase genetic variation and thus improve survival chances. This in itself is not the problem. It is the assumption that the mutation occurred because of the conditions that is.
Evolution is a chance theory. Nothing happens as a cause of something else. There are no tiny people controlling the genes. And the DNA does not react to the situation. A beneficial mutation may arise, but it does not come about because of the situation. It arises as an error which happens to be benefical because of the situation.
In Christ.
