EVOLUTION: what about this

[The_Barbarian]

The bacteria who survived already had a tolerance to the toxin. How do we know? Because they were able to survive.

Nothing evolved, the parents had the ability already. Nothing new was passed on to their offspring.

No, that’s wrong. How do we know you’re wrong?

The Luria-Delbrück experiment (1943) (also called the Fluctuation Test) demonstrates that in bacteria, genetic mutations arise in the absence of selection, rather than being a response to selection. Therefore, Darwin’s theory of natural selection acting on random mutations applies to bacteria as well as to more complex organisms. Max Delbrück and Salvador Luria won the 1969 Nobel Prize in Physiology or Medicine in part for this work.

No, that’s incorrect. Evolution means change. In macro-forms, that means fish to man. Bacteria always remain bacteria.
