>without reading the rest of your post, I would counter this by saying that dramatic changes to a stable genome will only occur under evolutionary pressure.

I don't think you properly interpreted the experiment. Allelle frequencies vary, and saying something in the environment is causing genetic pattern changes is literally Lamarckism, but the main point of the experiment was to demonstrate how mutations in the genome will lead to changes as this is the primary vehicle for Darwinian evolution. 'Pressures' are irrelevant; fitness is everything. If a certain strain has an advantage over the other then it will proliferate while the other is outcompeted. In a cell culture, these organisms are naturally existing in a closed ecosystem with finite resources, hence why the experiment has run continuously rather than being interrupted or done in repeated intervals. What was found is that genes shuffle, shift, activate, and deactivate; however, one gene won't suddenly change into another or create more brand-new genes from scratch. Manipulating the ecosystem doesn't suddenly start seeing species increase in complexity, and this experiment proves that time alone isn't enough for random gene mutation to lead to macroevolution/speciation.

Yes and eventually the genome that adapts to that specific environment emerges and mutations are no longer as beneficial and don't propagate which results in a stable species. 

It's a static environment, why would change occur?

Forgot to include (you) in the other post, but like I said there, neutral mutations that are outside the bounds of selective pressure should still accumulate in the genome of the Bacteria regardless of whether the ecosystem is dynamic or static. After thousands of generations their overall genome has hardly been altered, which is something that should be impossible or highly improbable if random mutation is truly the vehicle for evolution. Instead what we see is that species utilize epigenetics and certain recessives to shuffle traits within a population to maximise population health; however, we aren't seeing new genes get created or increase in complexity. That was the whole meat of the experiment.

You make a good point with the absence of neutral mutations, but I think there are too many variables to draw conclusions from it. For instance, mutations are rare, and a neutral one in a system without pressure will *barely* propagate. So your sample is more likely to get bacteria with unchanged genomes.

It's like one person having a neutral mutation and having one kid with a person, thousands of generations later that neutral mutations will be in like .000000000001% of the total 20billion population, or whatever it is in the future, so detecting it in a random sample would be nearly impossible.

I'm gonna bring in another example to clear this up if that's okay. If we go with the official record for the divergence of the tribes Pan and Homo that led to modern Chimps and Humans respectively then we'd go back 9 million years. Assuming a generous 20 year generation time that would yeild ~450,000 generations from then to the current point; however, between Chimps and Humans there are about 40 million unique allelle differences (in both coding and non-coding portions) within the DNA. Spliting that in half to 20 million for each tribe would mean that there would need to be ~44 gene mutations per generation to get from an ape ancestor to a bipedal AMH. That's beyond preposterous, even taking into account that we likely have a much greater share of those 40 million mutations that separate us from Chimps. That's a combination of all three mutation types that are present in us but not in Chimps. This level of divergence is impossible under the current darwinist model, hence why I brought up the E. coli experiments as a more grounded reference. Regardless of rate of mutation, it would have to be breakneck in order to even get a transformation as basic as one ape turning into another, let alone a fish becoming an amphibian.

are you actually retarded?

There are 40millions different nucleotides between humans and chimps, but we have fucking 3 billions pairs of nucleotides. so expecting a change off 44 nucleotide mutations per generation (44/3000000000), a change of 0.000002% between generations, is more than reasonable. the difference we can find between individuals can even reach up to 0.1%...
