Now what ?
Researchers at the University of Idaho ran an experiment on E. coli strains to see if they could ''evolve'' aerobic citrate utilization as Lenski's lab had finally achieved after 33,000 generations, which took 15 years. They showed that a mere 12 generations were needed to see the beginnings of citrate utilization and a mere 100 generations to see the refinement of it. Again, no new genes arose, only the duplication and rearrangement of existing genes.
And what happened to the fruit flies a while back all science was excited about ?
You and noble mouse clearly have not read the research. The researchers have observed reversions, insertions, deletions, substitutions, insertion sequence mutations, element insertions, and duplications such as the one you had mentioned. Much more than just that single duplication. All of which, fixated via natural selection.
So, back to noble mouses original statement.
"In other words, the mutation did not create new genetic information that was utilized"
In fact, many mutations, insertions, deletions, reversions, duplications, subtitutions and more, 40+ beneficial mutations, were observed to have fixated and were utilized, as the ecoli increased in fitness.
And the above referenced mutations, have created new genetic information that has been utilized.
And its still happening. And its still being observed.
Do you understand 4x4?
And, it is irrelevant whether these mutations occurred by 500 generations, 1000, 10,000, 20,000, 40,000, 60000 etc. It really doesn't matter when these mutations occurred, the fact is, they occurred. It was observed, and they have produced new DNA that did not historically exist, in combinations and orders that did not historically exist. And those mutations were fixated via natural selection, which resulted in increased fitness and alterations in phenotypic properties of the bacteria.
