Sex born from hard rock and heavy metal
New Scientist ^ | 19 June 2012 | Will Ferguson

The origin of sexual reproduction was one of the most important events in the history of life—and it would not have been possible without granite. The igneous rock began forming in vast quantities around 2 billion years ago, bringing to the surface the metals that fuel complex life.

Life relies on a number of heavy metals to form proteins. Zinc, molybdenum and copper are particularly important for the eukaryotes—a group that includes animals, plants and fungi, all of which may reproduce sexually.

These complex organisms probably did not become widespread until the oceans became rich in the metals about 800 million years ago, but last year fossil evidence emerged showing that eukaryotes were living in freshwater lakes on land at least 1 billion years ago. So where did they get their heavy metal fix?

John Parnell at the University of Aberdeen, UK, and colleagues studied the rock record and say that an important event was the formation of an ancient supercontinent called Nuna, or Columbia, about 1.9 billion years ago, during the Palaeoproterozoic. …

When Nuna formed, large bodies of magma were injected into the continental crust where they cooled to form granite. This igneous rock is rich in metals including zinc, molybdenum and copper. Over time, natural erosion brought the granite to the surface where it, too, eroded, releasing the metals into the soil and water. Sedimentary records show that they were present in near-surface reservoirs and shallow bodies of water by 1 to 1.5 billion years ago, says Parnell.

"These metals were used by early cells to develop enzymes that enabled them to carry out a greater diversity of functions and begin to sexually reproduce," says Parnell. "They gave early life the added dimension of natural selection and variability." …

Actually, sex was invented by the Communists to corrupt young people.

That's why it took so long to catch on down South. Why, back in the day sex was unheard of down here! But I'm afraid things have changed. Now there are even a few rumors that it's reached as far as Natchez.

We're probably doomed.

The theory of evolution of the Coca Cola can.

Billions of years ago, a big bang produced a large rock. As the rock cooled, sweet brown liquid formed on its surface. As time passed, aluminum formed itself into a can, a lid, and a tab. Millions of years later, red and white paint fell from the sky, and formed itself into the words “Coca Cola 12 fluid ounces.”

Of course, my theory is an insult to your intellect, because you know that if the Coca Cola can is made, there must be a maker. If it is designed, there must be a designer. The alternative, that it happened by chance or accident, is to move into an intellectual free zone.

Now we know why rocks were so important to the Flintstones.

"Unanswered is the question of “How did it come to pass that a population of organisms generated dual mutations simultaneous in time and space to produce a ‘male’ component and a ‘female’ component, which attached to each other and produced a new ‘male’ organism and the same thing happened twice and somehow produced a new ‘female’ organism, which then ended up in the same place and time to start reproducing sexually?”"

They were omnisexual until a mutation resulted in a protien(hormone) that caused them to specialize. Testosterone is what causes the default female to become male.

It takes great faith and a huge commitment to irrationality to be an atheistic scientist. Don’t even get me started on the arbitrary nature of it all. Man goes to unbelievable lengths to deny God.

The God of the bible is way to perfect to create something so irrational and arbitrary.

I think it would suck to be as powerful as he is and too know everything that is going to happen before it does happen. That would suck even to God.

Maybe he wanted something to thrill him-give him a challenge so to speak? Maybe even he wanted to see what would happen if he did not get involved for s***s and giggles...and I am being serious here.

Impossible as to do so would violate his sovereign nature. He doesn’t need to be challenged to be happy. He is a blessed God (happy), fulfilled in Himself. He is not like us but in some ways we are like Him. A perfect God has no needs. He says in scripture, if I were hungry I wouldn’t tell you.

The real argument is not between those who believe the universe was created 6000 years ago and those who believe the universe was created 15 billion years ago.

The real argument is between those who believe the universe willed itself into existence from nothing, and those who believe it was created by God.

Which reminds me, I just bought a copy of Herman Melville’s MOBY DICK.

The real argument is between those that would bow the knee to King Jesus and those that refuse. I liked your summation though.

At least it wasn’t born from rap.

You sure are limiting God, aren’t you. Not to mention leaving no possibility for the existence of a devil who would lie about Him.
