Are scientists actually observing macroevolution in bacteria?

by Helen Fryman

Question: Are scientists actually observing macroevolution as it happens in bacteria?

Response: That depends on how "macroevolution" is defined. Scientists have seen bacteria exchange genetic material. They have seen bacteria become antibiotic resistant. They have seen bacteria become bigger from mutations. But have they ever seen bacteria become anything other than bacteria? No. Have they ever seen one type of bacteria, such as E.coli, become some other type of bacteria that is not (in this case) E.coli? No, they haven't. In fact, with over a hundred years of work with E.coli behind us, (at 20 minutes per generation time, that's over 2 1/5 MILLION generations of E.coli minimum that have been witnessed), and despite forcing or encouraging mutations, they still cannot get anything but E.coli. So it's your call. Is that macroevolution? By some evolutionists' standards it qualifies.
