Birth-death models in macroevolution

WebIn this article, we investigate the macroevolutionary predictions of an individual-based birth-death model (BD I model) where speciation and extinction rates emerge from population dynamics. We start with the simplest neutral model in which every individual has the same per capita rates of birth, death, and speciation.
