Protocells Reproduce Morphological And Chemical Signatures Of Early Microfossils
[biorxiv.org] Identification of early microfossils relies on morphological and chemical criteria assumed to be unique to life, but whether abiotic microstructures can satisfy these criteria has not been rigorously tested.

![Hypergraph percolation accelerates the emergence of large-scale biological organization. The growth of integrated organizational complexity is compared in systems governed by pairwise interactions and higher-order hypergraph interactions. Complexity is quantified as the percentage of elementary units incorporated into the largest connected organizational assembly as interaction density increases. The pairwise model exhibits a gradual increase in connectivity, whereas the hypergraph model displays a sharp transition associated with the formation of extensive higherorder connectivity. Inset A enlarges the transition region and shows the growth of the largest connected component as a function of interaction density. Therefore, higher-order interactions can generate abrupt increases in large-scale organization through hypergraph percolation dynamics. -- [q-bio.OT]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/07/From-simple-interactions.png?resize=1200%2C720&ssl=1)
