Webb模板:Evolutionary biology. 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 …

WebbPrebiological coevolution of reproducers and replicators: a conceptual scenario and model framework. Protocells with (blue) and without (yellow) GE compete for common resources (black circles). The double outline denotes the lipid bilayer membrane of the protocells. The GE in the protocells are either autonomous (purple) or nonautonomous (green). Webb- Fossil remains and sedimentary rock provide evidence to evolution because the under levels of fossils are very dissimilar to the upper levels of fossils. This shows that over time species have adapted and evolved.

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.
