It will eventually be possible to directly verify it when the technology is available. A number of hurdles are still in the way, but they could be jumped at any time. One main hurdle currently is the problem of deriving the protein shape produced by any given sequence of DNA.
Once such hurdles are overcome it will be possible to simulate the expression of genes on a computer. It will be possible for example to take a known gene and randomly alter it and see if that alteration is a valid gene. Imagine doing one million different alterations and counting how many of them produce valid genes, and then being able to determine how they differ. This will allow evolutionary pathways between different genes to be found, something that is currently outside the ability of technology and knowledge.
The long term goal would be to simulate the growth of entire organisms on a computer based on their DNA. The benefit of doing this on a computer rather than real life is that time is no longer a contraint. A fast enough computer could simulate one million generations of a population of bacteria in a matter of seconds for example.
That is a statement of faith in things hoped for but which are not seen, just as described by the Apostle Paul in the New Testiment.
It is OK to cover the gaps in our knowledge with statements of faith. I do it all the time.
Thanks for saying that it HASN'T been done.
This appears to be an admission that evolution is largely based on speculation.
You'd have to parameterize the daylights out of all the individual atomic and molecular interactions within the proteins in order to solve the energetics...and that would affect your accuracy...and that would affect the predicted structures.
Not just yet, IMHO.
