![]() My approach to science is the correct way because I question everything and don't accept a fossil record with like 4 fossils of monkeys saying I am a monkey

Please stop referring to me as an atheist as I am not. I have a personal moral code that is not based on some over told stories, but instead by life experience. | |||

If not we would still be keeping slaves, killing our children by stoning if they don't honor their parents, and stoning adulterers and homosexuals. Its unfortunate that there are people (e.g. Tea Party nutcases) who would actually go back to morality as set forth in the Bible, but those of us who have a well developed secular morality (eg atheists and religious people who choose to ignore most of the Bible) will not permit such backsliding. Religious morals is an oxymoron. Regards, Mg

![]() Additionally, we've identified the molecular solutions that microorganisms have developed to protect themselves against antibiotics. In some cases, general xenobiotic enzymes are mutated to accept these new molecules as substrates, allowing them to catalyze chemical reactions which inactivate the antibiotics by changing their molecular structures and interrupting their function as potent protein inhibitors. In other cases general efflux pumpes are mutated to remove the antibiotic from the cell, keeping it below the working concentration. In other cases, the protein targets of the antibiotics have mutated, and the antibiotic no longer properly inhibits them. In other cases, horizontal gene transfer appears to be the culprit. The vast majority of antibiotics are natural compounds or semi synthetic derivatives of natural compounds. The biosynthetic machinery of these compounds evolved as weapons factories in a molecular arms race between microbes competing for nutrients. The microbial host that produces the antibiotic has to have its own resistance mechanism, and the theft of the genetic code for this resistance (horizontal gene transfer) allows a previously susceptible organism to gain resistance.
All of these mechanisms are genetically encoded, and their appearance represents a chance in the genetic code which is subsequently heritable. That's fucking evolution. | ||

![]() Science hardly explains everything, but at least what it does explain is more or less indisputable (not talking about advanced physics, more like Newtonian).
