The article that I reviewed was called "When oxygen disappeared, early marine animals really started evolving" by Lucas Joel. The title of the article grabbed my attention right away simply because I was curious to know how lack of oxygen can help marine animals evolve. The article discussed how scientist discovered that the deeper into the ocean they went in the more they saw many creatures that had different characteristics and that seemed to have evolved. They noticed that the deeper into the ocean and the less oxygen, the more the sea creatures seem to have evolved. They came to the conclusion that sea animals tend to evolve with the less exposure to oxygen and the changes to the oxygen exposure has a major impact in their development and evolution.
