A University of Alberta geomicrobiologist and his PhD student are part of a research team that has identified phosphorus as the mystery ingredient that pushed oxygen levels in the oceans high enough to establish the first animals on Earth 750 million years ago.
By examining ancient-ocean sediments, Kurt Konhauser, student Stefan Lalonde and other colleagues discovered that as the last glacier to encircle Earth receded, leaving behind glacial debris containing phosphorus that washed into the oceans. Phosphorus is an essential nutrient that promoted the growth of cyanobacteria, or blue-green-algae, and its metabolic byproduct is oxygen. The new, higher oxygen levels in the ocean reached a threshold favourable for animals to evolve.
Konhauser's past research into ancient phosphorus levels in a unique suite of rocks called banded iron formations led him and his colleagues at the University of California Riverside to their current findings.
In 2007, Konhauser and his U of A team published research in the magazine Science that was contrary to the then-accepted theory that phosphorus was scarce throughout much of Earth's history, it was in fact plentiful.
"Now in 2010 we showed that phosphorus levels actually peaked between 750 and 635 million years ago at the very same time that oxygen levels increased, allowing complex life forms to emerge," says Lalonde. "That establishes our link between phosphorus and the evolution of animals."

So maybe what we were putting in was good for the fishies???

Nobody has explained how the volatile and extremely unstable element Oxygen was harnessed by life to do work. Either the molecules were intelligent, or they had intelligence guiding them.
Else the same chance processes that made oxygen work for life in one instance would destroy it in the next.
How many weeks before this theory is shot down? Poor evolutionists, nobody believes.

Whoops!!!!
Its “Snap Your Finger” time...
So, because science doesn’t have an answer for your question, then intelligent design must be true? You’re conclusion is worthless and have zero to add to the discussion. Argument from ignorance. Thanks for playing.

“Phosphorous levels peaked...”
Hmmmmm....
I wonder where it went since then.
Really.
I’m wonderin!
Oh man. Can I quit eating the bananas now...I thought they said potassium.
Eat glow worms?
Hmmm...
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.
So, because scientists invent answers for your questions about the distant past, without any hard evidence other than their prejudiced interpretations of data existing only in the present, then intelligent design must be false? Your conclusion is worthless and has zero to add to the discussion. Argument from Ignorance. Thanks for playing.
See? Works both ways.
the only thing you can say about evolution is evolutionists have the thinist skin ever evolved.
So evolution exists thanks to consensus between corrupt scientists. Same buch and tactic that brought us Global Scamming. Same peer review tactic too as your post so perfectly demonstrates.

Actually, one of the first mass extinctions was caused by oxygen. Oxygen is lethal to many microbes.
Man is ex-corpus and returning to the sea as mineral? Not that I don’t feel that way at times but I was hoping for some better future. ;-)
No, a shameless substitution of words doesn't.
Your way relies on testimony. Science relies on experiment with evidence. In yours, you have to wonder if testimony is given by a nut, a liar, or a non tangible spirit. There is no way to know for sure. Science relies on concrete evidence with tests that can be duplicated by critics. This is a big difference.
