A century-old model for life's origin gets significant substantiation

A 'walk' in composition space for a lipid world molecular assembly, shown in simplified 3 dimensions. A point on the line signifies a specific composition along the time axis, whereby the three coordinates are amounts of the three different molecule types. A composome (pink background) is a time interval when the composition stays almost unchanged, signifying compositional replication. Credit: Weizmann Institute of Science

In 1924, Russian biochemist Alexander Oparin claimed that life on Earth developed through gradual chemical changes of organic molecules, in the "primordial soup" which likely existed on Earth four billion years ago. In his view, the complex combination of lifeless molecules, joining forces within small oily droplets, could assume life faculties—self-replication, selection and evolution. These ideas were received with considerable doubt, still pertaining today.

This is how I understand it happened: from lipids.
