First, METHANOGENS ARE NOT BACTERIA THEY'RE ARCHAE! Next, when oxygen increased because methanogens starved (because of the nickel famine) that was the age of dinosaurs with 33% of the atmosphere was oxygen. Today it's only 23% that's why dinosaurs can't survive today, there isn't enough oxygen to sustain life for them. Also if there was 33% oxygen today, bugs would be 10 times bigger. The nickel famine's source was the cooling of the mantle, causing less volcanic eruptions and less nickel out of the mantle.
We didn't understand a lot of this article, but all that we took off of it was that Methanogens were happy until 2.5 billion years ago, and that they create methane. We swear that we read the whole thing, but it was just VERY confusing.
BAD! Boring! So confusing! I couldn't understand this a bit! What do they mean like the water went down to like a nickel! This was so bad that I couldn't bare to read it anymore about half way. Please don't post anything like it again!
I'm serious, I don't know what they are talking about, I don't understand the nickel thing.
THis was really interesting to read about because i never knew that the cooling of the earth's mantle could have spiked/sparked such a change in the earth's organisms. I didn't know that the decrease of one element could be such a change in the entire history of the earth. I found out more on this subject at: http://esciencenews.com/articles/2009/04/08/a.new.link.between.nickel.methane.gas.and.evolution.complex.life.forms.earth .
Whaaaat? I understand that methanogens are archae like parsa said, but what I think the article says, (besides confusing stuff) is that the level of the mineral nickel in the air went down by a ton, and the methanogens were not O.K. with that.
