Frozen scallops should be thawed in the refrigerator overnight. They can upgrade their insulation, seal leaky windows and doors, and add heat pumps or solar panels. This modern theory then suggests that life originated on Earth by means of a rather slow evolution of nonliving matter. Similar and, in some cases more extensive bans are happening around the world, from Norway to New York City. A third theory of lifes origin is known as chemical evolution.
