Royall's suggestion entails that the probabilistic process just described has the consequence that Present 5 0 provides strong evidence favoring Past 5 0 over Past 5 1, since the likelihood The second property we stipulate is sometimes referred to, in the timehomogeneous, finite-state setting, as the Markov chain's being "regular"; we How much information does that observation provide about the state of the population at some earlier time? case, the present state of the population provides information about its past Comparing Rij values for five processes, assuming infinite temporal separation of Past from Present and zero mutation. concerning the population's past state if trait A evolved because of natural selection. Frequency-dependent selection for the majority trait is better than drift in terms of how much information the present state of a lineage provides about its past. ./cache/work_vknqfhzydfgclg7xv5i4j4stra.pdf ./txt/work_vknqfhzydfgclg7xv5i4j4stra.txt
