Phosphorus identified as the missing link in evolution of animals

Science relies on concrete evidence with tests that can be duplicated by critics.

kinda like that global warming thing?

Bananas have appeal.

Bananas have appeal.

Thanks a bunch for that.

Okay, You have proven you have no idea what a theory is and how science works, good show. Poor creationists, not scientists or experts, but pretend to be. Yeah, those 100,000+ peer reviewed paper published since 1973 supporting the theory of evolution, compared to 0 from all of the creation ‘scientists’ young earth creationists, old earth creationists, and IDers put together.... I’ll wait here while you to start refuting them, and expose this big 150 year old conspiracy. Hope you don’t mind if I don’t hold my breath.

> Science relies on concrete evidence

All I saw in that article was conjecture about what the evidence means.

The origin of life is not repeatable, neither is the emergence of a bat from a shrew.

And imagine the irony of the announcement that, after millions of man-hours of investigation and experimentation, by thousands of scientists in laboratories all over the world, using billions of dollars worth of the latest state-of-the-art laboratory equipment, a primitive life form has been created, proving once and for all, no intelligence is necessary to create life.

[plain talk]

Yep. Evolutionist slugs will just graze somewhere else and hope for continued funding.

I’ve been plaintain puns all over FR all night.

A little help here. If the oldest KNOWN age of the ocean floor is ~180 MILLION YEARS OLD, how does one find 750 MYO sediment??? Go slow, I'm a layman.

[bray]

Same exact argument that was made about Climate Change. I used to believe in evolution but just didn’t have the faith to believe in rocks. After 150 yrs you would think somebody would find one transtitionary fossil?

Initially there is theorized to be one continent named Pangea:

Sea floor spreading began about 175 million years ago:

Hmmm..."

I think you meant "zzzzzzzzzzzzzzz", JD ;~)

Sea floor spreading began about 175 million years ago:

Understood, and that was my point. So where would we go to find OLDER ocean sediment, say, 750 million years old? Maybe I'm missing something here.

[epithermal]

OK, I see what you are asking. 750 million puts you in the Precambrian, where you do still find basins with sediment that formed on Pangea. One I am a little familiar with is the Belt group of sediments in Idaho and Montana. For a description of them you can start reading here if you want:

Well OK, big ((DUH)) on my part. Going back to the article it mentions their working with “banded iron” formations(high and dry ROCKS) that were seafloor a long time ago in an ocean far far away — or something... ;^)

[epithermal]

This isn’t the type of stuff anyone really needs to worry about, unless you are looking for mineral deposits! Here is some info on banded iron formations:

http://en.wikipedia.org/wiki/Banded_iron_formation

I tried to find out which banded iron formation the authors studied, but the article is a pay per view and all I found was an abstract here that doesn’t say:

http://www.nature.com/nature/journal/v467/n7319/full/nature09485.html

But, I was looking at the web site of one of the authors and I think they were studying samples of the Dales Gorge banded iron formation in Australia, from which they mine a lot of iron ore. If you go to this page and read the section he has on banded iron, he has some references on the Dales Gorge:

There is a link to an article on this page that has a description of the Dales Gorge banded iron formation:

Pecoits, E., Gingras, M.K., Kappler, A., Posth, N.R., Barley, M.A., and Konhauser, K.O., 2009. Petrography and trace element geochemistry of Dales Gorge banded iron formation: Paragenetic sequence, source and implications for palaeo-ocean chemistry. Precambrian Research, 172:163-187.

Thanks for the additional links and info.

That right there is the crux. After following some of your links and others I've come to the unscientific conclusion that this much ado about nothing.

...last glacier to encircle Earth receded, leaving behind glacial debris containing phosphorus that washed into the oceans...

Well, while you don't hold your breath, you might try to speculate where exactly the glaciers obtained all the phosphorus that eventually washed into the oceans. Was it miracled into them?
