The code allowing certain variations under certain circumstance which ALWAYS seems very limited is hardly a proof of evolution.

& it happened in 11 days (<800 generations). What new functions could be developed in 4 billion years?

How do you develop complex new set of codes gradually since we don't witness them continuously AT ALL in real life?

When resources are more scarce selection pressure weeds out the less fit ones. Really cool relationship btw community diversity & speed of evolution to a new environment.

These are very controlled & optimized conditions. Without competition from other species (only between slightly different strains) the bacteria can run free.

Slowly evolving multiple antibiotic resistances & becoming a real problem for hospitals. It sounds like you want an example of a new animal that has like some new arm or something.

Well its most easy to see evolution in bacteria because there are so many of them & they have short generation times. Eg Methicillin-resistant Staphylococcus aureus.

What you call evolution of bacteria I call it adaptation of limited parameters.

umm.... ok.

Second eg mutations in a second copy of a gene happens more quickly bc organism is not relying on the gene to perform its original function.

(Eg when oxygen could be used as an electron acceptor). All of a sudden the organisms have all the energy they could want. Under these conditions, the number of mutants increases.

In nature everything is under constant pressure to survive, leaving little room for this “experimentation” between strains. Room is given when there are large shifts.
