evolution?

[MeAndYou]

First, I understand many people believe evolution has already been proven, and many people believe evolution is not possible. I'm not here to rant or start arguments.

There was an article published that spoke of research done with molecules to understand darwinian evolution.

In short the research was done on two separate"species" of molecule with 1 food source to compete for. The fittest survived while the other slowly died off. The same test was done except with 5 different types of food source. This time both molecules adapted to grow "fond" of 1 particular food source different from the other species of molecule, each evolving differently as a result.

That seems quite pretty on the surface but anyone who studied science past 12 should be able to point out molecules are not alive and therefor require food.
Simplifying things for people isn't always such a good idea. That said, if what you mean to say is that one species of bascteria had a mutation which allowed it to better survive than those which did not it'd be brilliant.
But honestly, if you get a human and a cow and feed each nothing but grass and the person dies, it doesn't prove anything which is essentially the same as putting two seperate strains in a single petri dish and noticing one thrives off a food source than another.


However, going back to the simplistic veiw, if you wish to point out evidence of evolution, you need look no futher than any dinosaur. When they roamed the earth, humans did not, Wooly Mamoths, Sabre Tooth Tigers which we admittedly shared a timeline with BUT it is evidence of how species die off or change into other species.
Elephants, Large cats, common ancestry.

Darwinian theory (fact now as far as most scientist are concerned) in microcosm; natural selection & random mutation! Interesting article.

Issaccs: What is life, if not a large sequence of replicating DNA molecules?.. This study used self-replicating RNA molecules, which are simplified versions of DNA molecules [and which are still used in some life forms]

These molecules:
Moved
Consumed fuel
Reproduced
Adapted
Responded to stimuli

Sounds pretty much life, to me.

The article was a very good read, and demonstrated some things very nicely [and accurately]

My issue is comparing RNA strands too say, Ammonia or water.
That said, RNA is used in human DNA and as I'm aware every other species on earth.

They're using RNA strands, not ammonia or water.

I do believe in evolution as being the one constant of the the universe and our creation.

To God, Billions of years can be just a few days to the All High & Mighty.
