Penicillin resistance: acquisition of the B-lactamase.
fluoriqunone resistance: improvements in efflux pumps.
You are not even wrong. Which is hardly surprising, since you know nothing about biology.
For those watching the thread, notice the ridiculing nature of this reply (#313) to my last post. I have not included the entire post but you can go back and read it if you wish. Notice the lack of any coherent response. This is typical through out theads that challange evolution hypothesis. When there is no intelligent rebut, there is always redicule and personal attack.
The one misleading reply was the one above. Bacteria have many ways of acquiring defense from antibiotics. As with the B-lactamase it can be acquired from other bacterium that has been destroyed then can uptake the naked DNA leading to homologous transformation. This can lead to coding for altered Penicillin binding proteins, defeating the Penicillins b-lactams. Another route is by conjugation, transfer of resistance plasmids from one bacterium from another.
b-lactamase predates Penicillin. Along with horizontal gene transfer there is no proof of any new evolution in your example.

- "In the most primitive life forms such as bacteria it was impossible to demonstrate any kind of linear evolution. The genetic codes of related and unrelated species showed routine mixing together of genetic material- either as a result of virus activity or cross species breeding."
