WebA starting point for a more realistic population model is the Yule process (α(i) = κ 2 i and β(i) = 0) also known as the pure birth process (Yule, 1925). The reasoning behind this model is as follows. Each member of the population will give “birth” to a new organism after an exponential time with rate κ 2 independent of every other member. WebJ.

WebBirth and death processes are an important class of Markov chains where there are only two transitions, \births" and \deaths". A process with no \deaths" is known as a pure-birth process, and one without \births" is called a pure-death process. Birth and death processes occur in biology, economics, demographics and queuing theory. 1 WebStochastic birth-death processes September 8, 2006 Here is the problem. Suppose we have a nite population of (for example) radioactive particles, with decay rate .

Web3.2The birth-death process model As we saw, the pure-birth model does not account for extinction. This assumption is fairly unrealistic for most phylogenetic datasets on a macroevolutionary time scale since the fos-sil record provides evidence of extinct lineages.
