Abstract

fetched live from OpenAlex

Some of the most interesting open questions about the origins of life and molecular sciences center on chemical evolution and the spontaneous generation of complex and functional chemical species. The processes that generated the spectacular biopolymers that underlay biology demonstrate an untapped, by modern science, creative potential. We have established a robust, facile, and generally applicable platform for observing and analyzing chemical evolution using complex mixtures. While previous studies have characterized the formation of proto-polymers via chemical reactions, we systematically studied the process itself. We report empirical outcomes that were not foreseen or predicted. We have constructed an experimental platform to study the evolution of chemical systems that: (i) undergoes continuous recursive change with transitions to new chemical spaces while not converging throughout the course of the experiment, (ii) demonstrates chemical selection, during which combinatorial explosion is avoided, (iii) maintains synchronicity of molecular sub-populations, and (iv) harvests environmental energy that is stored in chemical energy. We have established some general guidelines for conducting chemical evolution. Our results suggest that chemical evolution can be adapted to produce a broad array of molecules with novel structures and functions.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
