No clearly it does not bother me that my answer does not fit what you are looking for...
Simply put
IT IS STILL BACTERIA!!!
And I repeat to you what I said before.
Only a fool would think it would be anything other than a bacteria after a few days of expressing error prone DNA polymerase.
Now where does is “store” these mutations?
I really want to know just how wacky your model of living things are.
Do they carry around previous mutations in a tote bag?
