WebCan a replicase be found in the vast sequence space by random drift? We partially answer this question through a proof-of-concept study of the times of occurrence (hitting times) of some critical events in the origins of life for low-dimensional RNA sequences using a mathematical model and stochastic simulation studies from Python software. We …
WebThis approach to fitness can lead us into the tautology trap: fitness defined by those that survive better (post hoc), but the change may not have been due to natural selection (e.g. drift). With true Darwinian fitnesses we would be able to predict which genotype would survive better (fitness values assigned to genotype "before" generation ...
