If the research is correct and microbes are truly the most vital aspect for survival in this planet, there is one organism that is getting little attention. Maybe sponges that live in the deep depths of the ocean could be one of the most vital aspects for earth to aid living organisms. Fort each living organism there is a huge consumptions of oxygen happening, "If you want to be like us and have a brain, that's quite oxygen-demanding." Dr. Lenton the founder of this research, proposed the idea that when earth was formed, oxygen levels were too low to hold life. Yet when researchers found fossils that went back billions of years back, with them they found sponge fossils. As science has proved that there is evolution happening all around us, these organisms were one of the few to evolve with little oxygen available. This organism showed that it has evolved to become one of the creators of the oxygen levels that is now presently known. Yet being able to note, if they were able to find this organism that lived long before earth to withhold life, there is little to argue that maybe there were more small organisms like this one that helped, yet there are so out of the norm that they have not been discovered yet. As Dr. Lenton and his colleagues continued in this research, they tested to see how low of oxygen levels can they continue their regular routine. They lowered the oxygen level almost 4% lower than todays level of oxygen. To be realistic, that is very little oxygen comparing it to the present.
Continuing with the research they came about with the idea that billion years ago life wasn't able to evolve with little oxygen, these organisms, "acted as seawater filters." They would use up organic matter while also shooting out important nutrients that would sink to lower levels of the ocean for organisms to grow. The fact that most of the bacteria used photosynthesis to grow, sponges love eating bacteria so this means less oxygen going up to the surface. This was one of the harmful ideas known from sponges, yet they were the creators of being able to have, "an oxygen rich ocean" This allowed for many organisms living in the sea to evolve and produce sufficient oxygen to carry life. The problem with this is the fact that this research is open to so many paths to take, there is no clear idea and it can create so many theories and hypothesis which will lead to so many different conclusions. This will leave with the audience unclear and it will be hard to decide if all of these ideas are true or all just made up. One of the greatest articles I have read and is one that i will be following quite frequently but it will be hard to decide which path to choose or to really in fact believe every single one.Pictures URL: http://static01.nyt.com/images/2014/03/18/science/18zimmer/18zimmer-master1050.jpg
