WebOct 11, 2024 · These birth-death-sampling (BDS) models which are the focus of33 the present contribution, are also widely utilized in macroevolution to infer speciation and extinction rates34 over time... 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.
Webdom walks (e.g., Cornette & Lieberman 2004)-as opposed to models with explicit births and deaths-are also models that have informed macroevolutionary thinking, although their mathematical structure differs from that of the models to be dis-cussed here.
