These processes take a SDSU Men’s Basketball National Championship Game Matchup Tee 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.

Best SDSU Men’s Basketball National Championship Game Matchup Tee shirt
There are large areas of the SDSU Men’s Basketball National Championship Game Matchup Tee shirt which are oligotrophic, meaning that they contain an insufficient amount of nutrients to sustain any significant biomass. The largest of these areas are at the center of the subtropical gyres, in the vicinity of 30-40° north and south latitude. This happens because around those latitudes the large scale wind patterns transition from Westerlies, blowing to the east, to Trade Winds, blowing to the west. To a first order approximation, this means that the large scale winds tend towards zero in this region. If you have studied the Mid-Atlantic trade routes between Africa and North America, you have likely heard of the Horse Latitudes where, due to low winds, ships would become adrift for extended periods of time, often forced to kill or eat their horses due to lack of supplies.
