ScienceDaily: Slowing Evolution to Stop Drug Resistance
For years, evolutionists have pointed to antibiotic resistance as proof of evolution in action. The argument often amounts to this (in simplified form): the fact that certain organisms grow resistant to certain antibiotics is evidence for the evolutionary idea that all animals must have descended from a single ancestor. Collapsing the argument does make it seem a bit silly, but thats our point.
We certainly dont want to belittle the very real threat of dangerous organisms becoming immune to the best drugs we now have (though the vast majority of microbes are actually important to life). But we cringe when media reports continue to dredge up the word evolution for something that is certainly not that. Add this to the personified nature of a supposedly non-intelligent process (e.g., evolution creates, progresses, etc.), and you have a news story...

I see. So the article says that evolution is not evolution, and the biggest fault of the researchers is calling evolution evolution.
But, as always, this depends on what is meant by evolution
When it proves inconvenient just change the definition. Typical i/d tactic when the facts do not support your position just change the facts.
Lets take a look at some of the facts.
1. Variations exist with in all populations.
2. Some of that variation is heritable
3. Base pair sequences are encoded in a set of self-replicating molecules that form templates for making proteins.
4. Combinations of genes that did not previously exist may arise via Crossing over During meiosis, which alters the sequence of base pair on a chromosome.
5. Copying errors (mutations) can also arise; because the self-replication process is of imperfect (although high) fidelity; these mutations also increase the range of combinations of alleles in a gene pool.
6. These recombinations and errors produce a tendency for successfully increasing genetic divergence radiating outward from the initial state of the population.
7. Some of the heritable variations have an influence on the number of offspring able to reproduce in turn, including traits that affect mating opportunities or survival prospects for either individuals or close relatives.
8. Characteristics which tend to increase the number of an organisms offspring that are able to reproduce in turn; tend to become more common over generations and diffuse through a population; those that tend to decrease such prospects tend to become rarer.
9. Unrepresentative samplings which alters the relative frequency of the various alleles can occur in populations for reasons other than survival / reproduction advantages, a process known as genetic drift.
10. Migration of individuals from one population to another can lead to changes in the relative frequencies of alleles in the recipient population.
11. Populations of a single species that live in different environments are exposed to different conditions that can favor different traits. These environmental differences can cause two populations to accumulate divergent suites of characteristics.
12. A new species develops (often initiated by temporary environmental factors such as a period of geographic isolation) when sub-population acquires characteristics, which promote or guarantee reproductive isolation from the alternative population, limiting the diffusion of variations thereafter.
13. The combination of these effects tends to increase diversity of initially similar life forms over time.
14. Over the time frame from the late Hadean to the present, this becomes sufficient to explain both the diversity within and similarities between the forms of life observed on earth, including both living forms directly observed in the present, and extinct form indirectly observed from the fossil record.
Thats what Evolution IS! If you have a problem with Evolution you have a problem with one or more of these fourteen points. Which one is it? Provide any evidence of any of the points that are incorrect.
While the origins of life are a question of interest to evolutionary biologist and frequently studied in conjunction with researchers from other fields such as geochemistry and organic chemistry, the core of evolutionary theory itself does not rest on a foundation that requires any knowledge about the origins of life on earth. It is primarily concerned with the change and diversification of life after the origins of the earliest living things although there is not yet a consensus as to how to distinguish living from non-living
Evolution does NOT indicate that all variations are explained this way; that there are no other mechanisms by which variations may arise, be passed, or become prevalent; or that there is no other way life diversifies. Any and all of these may be valid topics for conjecture but without evidence, they arent science.
Other peoples opinions presented in the form of quotes are not evidence against the theory of evolution. They are merely opinions, and all people have opinions, which turn out to be false. So lets stick to the facts.
Culling plants by a breeder to produce a population predominately of a certain characteristic could be compared to the culling effect of antibiotics on organisms.
Evolution? Evolving into what?
Thanks for the ping!
This is the only part worthy of comment. So, it's "evolution", just not "molecules-to-man evolution"?? Evolution is as evolution does, Forrest. If it is "heritable changes in the genome (by mutation and/or, as is the case with bacterial antibiotic resistance, plasmid exchange) that make the offspring more genetically fit in a specific environment".....it is "evolution."
