real life , from yesterday saidQuote:Using the example of your body resisting a disease -- this is not evolution.
Oh but it is. Modifications start within the existing morphology and then are changed, bit by bit via selection. Sooner or later these changes are incorporated into a new type of organism that has no affinity (as in natural breeding) with the rootstock. Thisis almost the very statement that DArwin uses. I see that the newspaper cartoonists have hhad a good day quoting our president who, when he speaks of the "War on Avian Flu" he stumbles over the word "Mutation" so he doesnt imply evolution.
Opportunistic mutations within disease pathogens are a perfect example of the process of evolution. The virus or other pathogen (klike Rickettsia in Rocky Mtn fever) have evolved new "strategies " in order to infect more easily, develop a streamlined host sequence , or reducing lethality.
Englishmajor, you argue at the level of most Creationists in that
you imply that , once a mechanism is discovered, we should immediately try to duplicate it in the lab. The Miller and Urey experiment is routinely repeated by labs with increasingly more sophisticated analytical equipment and by adjusting conditions as they were in the early PreCambrian.
The only thing that has us unable to reproduce the creation of exact replicants is extreme ignorance of how. However, that doesnt mean that this ignorance hasnt spurred on research. 15 years ago, Creationists were arguing that no intermediate fossils exists and therefore evolution couldnt be modeled. Today, we have filled in most of the fossil gaps (in major phyla ), so the Creationist argument has been lost forever.
Weve already been able to create replicating molecules in the lab and discrete sections of nucleotide chains and even helices.
If you guys would only read the popularized (or professional) scientific literature rather than remaining obstinately ignorant by repeating the same lame statements which show a purposeful misunderstanding of what all these discoveries have proven, we would be much farther down the pike. But no, you wish to grab us and drag us back into the time when science had to hide and be approved by papal authority.
And , Id appreciate that you and your buddies would not try to legislate your fairy tales into the science curricula of our schools. If you guys wanna believe in evil spirits and magic floods and other preposterous moral tales, be my guest. Just please dont mess up our school systems any further.
