The Proterozoic-a time just before\nthe evolution of complex life. That means that the building blocks of life formed\nin this eon. That means lower temperatures (Yup! It took this long for the\ntemperature to go down after the VOLCANO ERUPTIONS.), and OXYGEN. We will talk\nabout that later. First, the Snowball Earth hypothesis. It sounds lame but bear\nwith me. Basically, many scientists believe that about 650 million years ago,\nthere was this Cryogenian period, where snow and ice covered the Earth almost\nentirely, SEVERAL TIMES. It was basically the Ice Age, but better and less well\nknown. <\/p>\n\n\n\n
The Great Oxidation Event. The\nfirst introduction of oxygen into the atmosphere 2.5 BILLION years ago. All due\nto photosynthesis from \n \n \ncyanobacteria, little, marine, bacterial\nplants. Before this, any oxygen which happened upon Earth was dissolved into\niron or organic matter, but once they became saturated, oxygen eventually grew\nin number. Now, before oxygen, bacteria were anaerobic, meaning they lived\nwithout air. However, as they were not used to oxygen, it was toxic for them,\nand they got wiped out (Bit hard to avoid poison when it is literally\nEVERYWHERE, isn\u2019t it? Quarantined people cannot agree more!). Oxygen also\nreacted with methane and reduced its concentration, making the planet colder\nand triggering an Ice Age (again), called the Huronian, which lasted 300\nmillion years (Didn\u2019t tell you there were two, did I?).<\/p>\n\n\n\n
As for life, no more were there\nhard-shelled bacteria, but rather soft-bodied Protista, fungi, and many others.\nOne of the most important was Bangiomorpha pubescens<\/em>, a species of red\nalgae, which was the first plant to genetically reproduce, instead of making a\nclone of itself. It may still be alive. However, there were many creatures who\nonly lasted a few million years and died out later. Like the Charnia<\/em>, an\nanimal which resembled a fern, but lived deep in the ocean, well below the\nlevel of photosynthesis. It was the first animal to reproduce genetically.\nOthers existed, though most looked like rocks. All the animals in this eon\nstayed anchored in one place all their lives, except for the Nemiana Simplex<\/em>,\nan ancestor of the jellyfish who may have fed on algae. I guess I can pull a\nmoral from this: Do not stay rooted in one place or do the same thing over and\nover; or else you\u2019ll die out. (Not the cheeriest moral.).<\/p>\n\n\n\n Shaurya Prasad (Grade 7 )
