I will get to this once I get my Evolution vs. Natural Selection post finished.unriggable wrote: if humanity is a single species, why do we all look different? Why was I born without an appendix, and most of us were? Why am I 6'3" even though my dad is 6'2"? Why are our toes smaller and our brains bigger and our bodies taller than our ancestors?
I have plenty of info on how there is diversity among a single species. And it is not evolution.
But first back to the EVOLVING BACTERIA.

ISSUE: Do Bacteria Evolve Resistance To Antibiotics?
FACTS:
Germs over time have developed a resistance to antibiotics. For instance, penicillin is generally now less effective than before.

Creation Assumptions:
- Designed to Adapt Furthermore, it has been proven that resistance to many modern antibiotics was present decades before their discovery. In 1845, sailors on an ill-fated Arctic expedition were buried in the permafrost and remained deeply frozen until their bodies were exhumed in 1986. Preservation was so complete that six strains of nineteenth-century bacteria found dormant in the contents of the sailors' intestines were able to be revived! When tested, these bacteria were found to possess resistance to several modern-day antibiotics, including penicillin. Such traits were obviously present prior to penicillin's discovery, and thus could not be an evolutionary development.

-Designed to Adapt bacteria did not āmutateā after being exposed to antibiotics; the mutations conferring the resistance were present in the bacterial population even prior to the discovery or use of the antibiotics.

-No new information passed by reproduction In a given population of bacteria, many genes are present which express themselves in a variety of ways. In a natural environment, the genes (and traits) are freely mixed. When exposed to an antibiotic, most of the microbes die. But some, through a fortuitous genetic recombination, possess a resistance to the antibiotic. They are the only ones to reproduce, and their descendants inherit the same genetic resistance. Over time, virtually all possess this resistance. Thus the population has lost the ability to produce individuals with a sensitivity to the antibiotic. No new genetic information was produced; indeed, genetic information was lost.
Creation Conclusion:
-The suggestion that the development in bacteria of resistance to antibiotics as a result of genetic mutations or DNA transposition somehow āprovesā organic evolution is flawed. Macroevolution requires change across phylogenetic boundaries (I.E. crossing from one species to the next http://en.wikipedia.org/wiki/Phylogenetic) . In the case of antibiotic-resistant bacteria, that has not occurred. No new information was added. Hence NOT EVOLUTION!
