Webb25 sep. 2024 · These so-called ‘protocells’ are the precursors to modern living cells, formed by prebiotically plausible molecules that self-assemble or aggregate into vesicles. Previous studies have identified fatty acids as likely molecules to model protocells because they are prebiotically plausible and can theoretically support a protocell life cycle. WebbSelf-assembly of cell membranes that encapsulated the polymers into populations of protocells were essential to the development of life forms in the prebiotic Earth. The primitive cell membranes enclosed the life-building molecules, defined the boundaries from environments, and enhanced chemical reactions inside protocells.

A protocell (or protobiont) is a self-organized, endogenously ordered, spherical collection of lipids proposed as a stepping-stone toward the origin of life. A central question in evolution is how simple protocells first arose and how they could differ in reproductive output, thus enabling the accumulation of novel biological …
