Life may have begun in similar regions. 13.10 - The abiotic synthesis of small organic molecules would have ben a first step in the origin of life.

Formation of Protocells Key stop in the origin of life would have been the isolation of collection of organic molecules within a membrane-enclose compartment. Laboratory experiments demonstrate that small membrane-enclosed sacs or vesicles form when lipids are mixed with water. When researchers add to the pic
