does the microbe resistance provide evidence of " evolution"?

Answer 1

I'm going to assume you mean antibiotic resistance. Consider this:

Penicillin was introduced in the 1940s

The first penicillin resistant bacteria was descirbed in 1943

Between 1979 and 1984 .02% of bacteria found in hospitals was antibiotic resistant

by 1994 6.6% of bacteria found in hospitals was antibiotic resistant.

Clearly antibiiotics act as a selection pressure. If any bacteria mutates to develop resistance to antibiotics, they have a clear selective advantage over other bacteria. Not surprisingly, after 50 years an increasing number of bacteria have evolved antibiotic resistance. Looks like pretty good evidence to me.

Answer 2

Microbe Resistance to antibiotics provides very good evidence of evolution.

Whereas most species take a long time to evolve, microbes can reproduce asexually and exponentially, so allowing a much quicker response to changes in the environment.

As the benefit of a resistance gene is so great (life for your offspring as opposed to death), the gene spreads easly and is easily detectable

Answer 3

Yes. The microbe changes its makeup to adapt to the presence of anti-microbials, and those that survive populate, giving evidence of evolution. However, note that this is evidence of micro-evolution and not of macroevolution.

Answer 4

This is an example of environmental pressure selecting for a particular genetic configuration within a species, and so is an example of microevolution. It is not, however, and example of such pressure resulting in the emergence of a new species (macroevolution).

Answer 5

It doesn't. I used to think that was a huge blow the creationist/intelligent design thought, but after taking advanced microbial control classes I learned that they have found drug resistant bacteria on Egyptian mummies. And trust me, the Egyptians didn't have Amoxicillin. Thanks.
