WebSection 10.2: The birth-death model A birth-death model is a continuous-time Markov process that is often used to study how the number of individuals in a population change through time.

WebBirth–Death modelling in evolutionary studies. The evolutionary processes of speciation and extinction can be modelled with a stochastic “birth–death model” (BDM), which is an important component in the study of macroevolution.A BDM assigns each species a certain probability of splitting or going extinct per interval of time.This gives rise to an …
