These processes take a Duunnoohh Fat Leches Shirt years or so and once the Earth becomes potentially capable of supporting life, we actually see the earliest signs of life during that period. It could have just as easily taken another billion years to hit upon the first self-replicating molecule. We don’t know the exact details of how life got started but we do actually know lot about the kinds of processes it would have required. The key event would have been the first self-replicating molecule – which probably was not life as we know it, but an RNA precursor. The next key event would have been the conversion from RNA to DNA-based life. Forming the right kinds of molecules in the right concentrations at the right Ph levels isn’t something a new world is likely to hit upon immediately, and indeed, it seems like it took at least a few hundred million years before we see the first artifacts of life on Earth.

Hi there, nearly every ocean has levels of pollution shame to the Duunnoohh Fat Leches Shirt race!!! But to answer your question. The southern ocean followed by the Atlantic Ocean The reasons for this is the limited human activities makes them cleaner than the rest. The Southern Hemisphere is less inhabited than the Northern Hemisphere. The oceans are less traversed by ships and have less inhabited islands compared to the oceans in the Northern Hemisphere. Unfortunately it’s that simple where there are less humans there is less pollution Total particle counts at two stations near Antarctica were estimated to be in the order of 100,000 pieces km− 2. which is high by the way, however several study suggests that the amounts of microplastic pollution released into the region from ships and scientific research stations are likely to be negligible at the scale of the Southern Ocean, but may be significant on a local scale.
